It must be in the euchromatin, distant from replication origins, and not transcribed (no genes, no ncRNA). It's probably the most boring part of the genome. It would be an added bonus if anyone has designed ChIP primers for it. Any suggestions? I will summarize and post. Thanks! Susan F.

I started with the single deleted mutant strains and mated them. After mating them I sporulated the mated cells, then I repeatedly streaked the diploid cells on selective plates to get haploids. Finally the cells grown on selective plates were streaked on phloxin B plates,which showed light pink colonies. And at the same time I did flow cytometry analysis with these double deleted mutant cells along with a different haploid strain as control. The mutant cell showed the same DNA content as the haploid cells. Is this process enough for checking haploid cells? Or can you suggest any other confirmatory experiment to check haploid cells?

Here are our recent results from a timecourse of incubation. Next week, I am having students look at whether the carrier DNA matters, whether the heat shock matters, whether the DMSO matters, and whether the DMSO should be added at the same time as the PEG rather than right before the heat shock. I welcome all guesses as to whether or not each of these changes will increase the number of transformants, decrease the number, or have no effect. Time course Number of colonies 30 min 28 60 min 84 120 min 100 180 min 140 240 min 524 (wow-is this reproducible?) 21 hours 10 24 hours 26 76 hours 24 Charlie Hoffman hoffmacs at bc.edu "I'd rather be fission" From klara at mail.nih.gov Thu Feb 2 16:19:32 2012 From: klara at mail.nih.gov (Amar) Date: Thu, 2 Feb 2012 11:19:32 -0500 Subject: [Pombelist] Haploids In-Reply-To: References: Message-ID: It is a trivial problem to deal with. Just dissect a few tetrads, grow segregants, check their markers. You will get your double mutant. If you don't get it, may be double mutant is dead. It will help to know if your deletions are tagged with drug markers. The way you are going about is indirect, problematic. How can you sporulate the mated guys, then keep streaking to select diploids. This is what S. cerevisiae people do, them get frustrated to conclude pombe is difficult organism and quit working on it. I know it as I have been a cereviisae person for years; see for example my short (7 pages) attached humorous memoir on budding yeast mating type studies. Just a thought. I hope my suggestion helps.

Many ts strains in pombe appear to grow enough that you see a colony, but all the cells have died (which you cannot see unless the phloxine B is there).

To screen the library and be confident you can or cannot clone the gene of interest (ie not there, toxic etc) you will have to screen about 100,000 colonies. I found that between 1 and 2000 colonies per plate was perfectly acceptable, so you can use 50-100 plates before you give up. Allow colonies to grow up for 4-7 days, then replica plate from this (1000 ish colonies per plate - see above) onto two YE (non selective) plates with phloxin. Incubate 1 plate at the permissive (27oC) temperature and 1 plate at the restrictive temperature (36oC) for 12-24 hours. Scan the restrictive (36oC) plate for the least red/pink colonies (i.e. those that grow best amongst their friends on the same plate). Compare the same colony on the 27oC plate. A successful complementation should be less obviously "better growing" compared to their friends (ie the surrounding colonies on the 27oC plate) than is obvious on the 36oC plate. Pick these colonies and streak to single cells on fresh YE (non selective)plates. Grow at the permissive temp (27oC) for 4-7 days until you have lots of individual colonies. Now replica these plates to two new plates: 1 YE+ phloxin to be incubated at the restrictive temperature (36oC) and the second, a minimal - ura plate, to be incubated at the permissive temperature (27oC). If you have a completing clone, the original plate should have had a mix of two types of colony: Type 1: plasmid containing. I.e. these show growth on minus ura plate at 27oC and less red on the YE+Ploxin plate at the restrictive temperature (36oC). Type 2. Plasmid is lost. I.e. these show no growth on Min -ura at 27oC and are very red on the YE phloxin at 36oC). If you have an integration, or a plasmid that doesn't complement, this will be obvious because you will not have the two types as above. Do NOT, whatever anybody advises you, waste time by trying to clone by directly transforming the library and plating on selective plates and then incubating these at 36oC. While this can work if you are lucky, but my experience is that, for greater than 50% of things I have tried, this does not work, for a variety of reasons. Since doing it properly involves only a few extra plates and a few extra days, you risk wasting much more time than you can potentially save by being "lucky" Finally, we have cloned over 30 genes from this library. I think in only one case did we have problems due to the gene not being there. This was a gene that was greater than 7kb in size.

My conditions for protein blotting are: 10mM CAPS pH10 (you need 11), 10% methanol, transfer: 100-150mA overnight in the cold room, with constant stirring. I think you may safely extend your transfer time. To improve the overall efficiency, I soak the gel?for 30 min?in the transfer buffer prior to transfer - to remove any SDS that might interfere with binding of proteins to the membrane. Good luck!

We are interested in how motor proteins and microtubules self-organize to generate large-scale structures and movements in the cell. The main projects in the lab focus on the mechanism of nuclear oscillations that help chromosome pairing in meiosis, the mechanisms of kinetochore capture and spindle assembly, as well as on segregation of damaged proteins in dividing cells. Our approach is live cell imaging of microtubules and motors at the single-molecule level in fission yeast and mammalian cells, in combination with genetic and biophysical manipulations, e.g., laser ablation. We aim at quantitative descriptions and development of simple theoretical models that help us understand the self-organization processes in the cell. We are seeking a highly motivated candidate for joining our interdisciplinary and international team. The applicant should have: - a PhD in Molecular Biology, Biochemistry or Physics, and less than 3 years of relevant postdoctoral experience - at least one publication in a peer-reviewed journal - expertise in: molecular genetics and biochemistry (for biologists), or statistical physics, nonlinear dynamics, and simulations (for physicists). Please send your application as a single PDF document containing a concise summary of previous work and research interests, a Curriculum Vitae, a publication list, and contact information of 2-3 potential referees to Iva Tolic-Norrelykke at tolic at mpi-cbg.de.

If so, what concentration and method of treatment was ideal?

We are using cerevisiae protocol that used to work nicely with budding yeast but the same protocol doesn't seem to work in fission yeast. We either not getting a signal at all or getting too high background, we suspect that it may have something to do with the efficiency of spheroplasting. We would really appreciate any advice on this and if you guys have a written protocol to share that would be very helpful! Thanks very much!

To screen the library and be confident you can or cannot clone the gene of interest (ie not there, toxic etc) you will have to screen about 100,000 colonies. I found that between 1 and 2000 colonies per plate was perfectly acceptable, so you can use 50-100 plates before you give up. Allow colonies to grow up for 4-7 days, then replica plate from this (1000 ish colonies per plate - see above) onto two YE (non selective) plates with phloxin. Incubate 1 plate at the permissive (27oC) temperature and 1 plate at the restrictive temperature (36oC) for 12-24 hours. Scan the restrictive (36oC) plate for the least red/pink colonies (i.e. those that grow best amongst their friends on the same plate). Compare the same colony on the 27oC plate. A successful complementation should be less obviously "better growing" compared to their friends (ie the surrounding colonies on the 27oC plate) than is obvious on the 36oC plate. Pick these colonies and streak to single cells on fresh YE (non selective)plates. Grow at the permissive temp (27oC) for 4-7 days until you have lots of individual colonies. Now replica these plates to two new plates: 1 YE+ phloxin to be incubated at the restrictive temperature (36oC) and the second, a minimal - ura plate, to be incubated at the permissive temperature (27oC). If you have a completing clone, the original plate should have had a mix of two types of colony: Type 1: plasmid containing. I.e. these show growth on minus ura plate at 27oC and less red on the YE+Ploxin plate at the restrictive temperature (36oC). Type 2. Plasmid is lost. I.e. these show no growth on Min -ura at 27oC and are very red on the YE phloxin at 36oC). If you have an integration, or a plasmid that doesn't complement, this will be obvious because you will not have the two types as above. Do NOT, whatever anybody advises you, waste time by trying to clone by directly transforming the library and plating on selective plates and then incubating these at 36oC. While this can work if you are lucky, but my experience is that, for greater than 50% of things I have tried, this does not work, for a variety of reasons. Since doing it properly involves only a few extra plates and a few extra days, you risk wasting much more time than you can potentially save by being "lucky" Finally, we have cloned over 30 genes from this library. I think in only one case did we have problems due to the gene not being there. This was a gene that was greater than 7kb in size.

Carr; URA-selection based). I would be grateful for any suggestions. For example, after transformation with the library the appearing colonies are all different sizes, later it is very difficult to select a "better growing" one on the high temperature plates. Any suggestion to circumvent this? One other problem is that often a colony would grow better just because of a plasmid containing a genomic piece with a metabolic enzyme. Could one reduce this background? Also what should I expect, how many colonies is it reasonable to screen? Any help would be greatly appreciated!

I recently tried EMM+G418 to make sure if it works or not. I compared my strains on EMM only and EMM+G418.?Unfortunately G418?didn't work at all on EMM for my strains. The reason?may be?that the amonium chloride in EMM media is competing with the drug so you need to substitute amonium with something else. This is also well explained in Dr. Forsburg's PombeNet page (http://www-bcf.usc.edu/~forsburg/drugs.html). PMG media is suggested instead of EMM for G418. ? PMG recipe: http://www-bcf.usc.edu/~forsburg/media.html#PMG ? I haven't tried yet but in your case you may have a problem with ura- strains?because it is also added as a bonus on PombeNet page where they say Ura- cells grow more similarly to Ura+ cells on PMG. It may work if you plate your cells first on YES+G418 and then replicate them on EMM-ura. ? Best Regards, ?

The standard salt solution added to minimal media does contain Na2SO4 at 14.1mM final concentration which would only increase to ~15mM, so shouldn't be a huge change in the anion concentration. Looking forward to hearing of your sage insights!

I started with the single deleted mutant strains and mated them. After mating them I sporulated the mated cells, then I repeatedly streaked the diploid cells on selective plates to get haploids. Finally the cells grown on selective plates were streaked on phloxin B plates,which showed light pink colonies. And at the same time I did flow cytometry analysis with these double deleted mutant cells along with a different haploid strain as control.

Here are our recent results from a timecourse of incubation. Next week, I am having students look at whether the carrier DNA matters, whether the heat shock matters, whether the DMSO matters, and whether the DMSO should be added at the same time as the PEG rather than right before the heat shock. I welcome all guesses as to whether or not each of these changes will increase the number of transformants, decrease the number, or have no effect.

Just dissect a few tetrads, grow segregants, check their markers. You will get your double mutant. If you don't get it, may be double mutant is dead. It will help to know if your deletions are tagged with drug markers. The way you are going about is indirect, problematic. How can you sporulate the mated guys, then keep streaking to select diploids. This is what S. cerevisiae people do, them get frustrated to conclude pombe is difficult organism and quit working on it. I know it as I have been a cereviisae person for years; see for example my short (7 pages) attached humorous memoir on budding yeast mating type studies. Just a thought. I hope my suggestion helps.

To screen the library and be confident you can or cannot clone the gene of interest (ie not there, toxic etc) you will have to screen about 100,000 colonies. I found that between 1 and 2000 colonies per plate was perfectly acceptable, so you can use 50-100 plates before you give up. Allow colonies to grow up for 4-7 days, then replica plate from this (1000 ish colonies per plate - see above) onto two YE (non selective) plates with phloxin. Incubate 1 plate at the permissive (27oC) temperature and 1 plate at the restrictive temperature (36oC) for 12-24 hours. Scan the restrictive (36oC) plate for the least red/pink colonies (i.e. those that grow best amongst their friends on the same plate). Compare the same colony on the 27oC plate. A successful complementation should be less obviously "better growing" compared to their friends (ie the surrounding colonies on the 27oC plate) than is obvious on the 36oC plate. Pick these colonies and streak to single cells on fresh YE (non selective)plates. Grow at the permissive temp (27oC) for 4-7 days until you have lots of individual colonies. Now replica these plates to two new plates: 1 YE+ phloxin to be incubated at the restrictive temperature (36oC) and the second, a minimal - ura plate, to be incubated at the permissive temperature (27oC). If you have a completing clone, the original plate should have had a mix of two types of colony: Type 1: plasmid containing. I.e. these show growth on minus ura plate at 27oC and less red on the YE+Ploxin plate at the restrictive temperature (36oC). Type 2. Plasmid is lost. I.e. these show no growth on Min -ura at 27oC and are very red on the YE phloxin at 36oC). If you have an integration, or a plasmid that doesn't complement, this will be obvious because you will not have the two types as above. Do NOT, whatever anybody advises you, waste time by trying to clone by directly transforming the library and plating on selective plates and then incubating these at 36oC. While this can work if you are lucky, but my experience is that, for greater than 50% of things I have tried, this does not work, for a variety of reasons. Since doing it properly involves only a few extra plates and a few extra days, you risk wasting much more time than you can potentially save by being "lucky" Finally, we have cloned over 30 genes from this library. I think in only one case did we have problems due to the gene not being there. This was a gene that was greater than 7kb in size.

My conditions for protein blotting are: 10mM CAPS pH10 (you need 11), 10% methanol, transfer: 100-150mA overnight in the cold room, with constant stirring. I think you may safely extend your transfer time. To improve the overall efficiency, I soak the gel?for 30 min?in the transfer buffer prior to transfer - to remove any SDS that might interfere with binding of proteins to the membrane. Good luck!

We are interested in how motor proteins and microtubules self-organize to generate large-scale structures and movements in the cell. The main projects in the lab focus on the mechanism of nuclear oscillations that help chromosome pairing in meiosis, the mechanisms of kinetochore capture and spindle assembly, as well as on segregation of damaged proteins in dividing cells. Our approach is live cell imaging of microtubules and motors at the single-molecule level in fission yeast and mammalian cells, in combination with genetic and biophysical manipulations, e.g., laser ablation. We aim at quantitative descriptions and development of simple theoretical models that help us understand the self-organization processes in the cell. We are seeking a highly motivated candidate for joining our interdisciplinary and international team. The applicant should have: - a PhD in Molecular Biology, Biochemistry or Physics, and less than 3 years of relevant postdoctoral experience - at least one publication in a peer-reviewed journal - expertise in: molecular genetics and biochemistry (for biologists), or statistical physics, nonlinear dynamics, and simulations (for physicists). Please send your application as a single PDF document containing a concise summary of previous work and research interests, a Curriculum Vitae, a publication list, and contact information of 2-3 potential referees to Iva Tolic-Norrelykke at tolic at mpi-cbg.de.

To screen the library and be confident you can or cannot clone the gene of interest (ie not there, toxic etc) you will have to screen about 100,000 colonies. I found that between 1 and 2000 colonies per plate was perfectly acceptable, so you can use 50-100 plates before you give up. Allow colonies to grow up for 4-7 days, then replica plate from this (1000 ish colonies per plate - see above) onto two YE (non selective) plates with phloxin. Incubate 1 plate at the permissive (27oC) temperature and 1 plate at the restrictive temperature (36oC) for 12-24 hours. Scan the restrictive (36oC) plate for the least red/pink colonies (i.e. those that grow best amongst their friends on the same plate). Compare the same colony on the 27oC plate. A successful complementation should be less obviously "better growing" compared to their friends (ie the surrounding colonies on the 27oC plate) than is obvious on the 36oC plate. Pick these colonies and streak to single cells on fresh YE (non selective)plates. Grow at the permissive temp (27oC) for 4-7 days until you have lots of individual colonies. Now replica these plates to two new plates: 1 YE+ phloxin to be incubated at the restrictive temperature (36oC) and the second, a minimal - ura plate, to be incubated at the permissive temperature (27oC). If you have a completing clone, the original plate should have had a mix of two types of colony: Type 1: plasmid containing. I.e. these show growth on minus ura plate at 27oC and less red on the YE+Ploxin plate at the restrictive temperature (36oC). Type 2. Plasmid is lost. I.e. these show no growth on Min -ura at 27oC and are very red on the YE phloxin at 36oC). If you have an integration, or a plasmid that doesn't complement, this will be obvious because you will not have the two types as above. Do NOT, whatever anybody advises you, waste time by trying to clone by directly transforming the library and plating on selective plates and then incubating these at 36oC. While this can work if you are lucky, but my experience is that, for greater than 50% of things I have tried, this does not work, for a variety of reasons. Since doing it properly involves only a few extra plates and a few extra days, you risk wasting much more time than you can potentially save by being "lucky" Finally, we have cloned over 30 genes from this library. I think in only one case did we have problems due to the gene not being there. This was a gene that was greater than 7kb in size.

Carr; URA-selection based). I would be grateful for any suggestions. For example, after transformation with the library the appearing colonies are all different sizes, later it is very difficult to select a "better growing" one on the high temperature plates. Any suggestion to circumvent this? One other problem is that often a colony would grow better just because of a plasmid containing a genomic piece with a metabolic enzyme. Could one reduce this background? Also what should I expect, how many colonies is it reasonable to screen? Any help would be greatly appreciated!

I recently tried EMM+G418 to make sure if it works or not. I compared my strains on EMM only and EMM+G418.?Unfortunately G418?didn't work at all on EMM for my strains. The reason?may be?that the amonium chloride in EMM media is competing with the drug so you need to substitute amonium with something else. This is also well explained in Dr. Forsburg's PombeNet page (http://www-bcf.usc.edu/~forsburg/drugs.html). PMG media is suggested instead of EMM for G418. ? PMG recipe: http://www-bcf.usc.edu/~forsburg/media.html#PMG ? I haven't tried yet but in your case you may have a problem with ura- strains?because it is also added as a bonus on PombeNet page where they say Ura- cells grow more similarly to Ura+ cells on PMG. It may work if you plate your cells first on YES+G418 and then replicate them on EMM-ura. ? Best Regards, ?

The standard salt solution added to minimal media does contain Na2SO4 at 14.1mM final concentration which would only increase to ~15mM, so shouldn't be a huge change in the anion concentration.

Actually we have tagged our gene of interest with GFP using Bahler?s method with G418 selection. The tag tends to be lost when culture is grown mitotically or during meiosis if crossed with another untagged strain in absence of the drug. Surprisingly even when crossed with another tagged strain in presence of G418 no viable spores appear on G418 plates during tetrad dissection. Can anyone suggest us a solution?

This map contains ~1.6 million measured interactions and covers more than 60% of the non-essential genes from virtually all major biological processes. We trust it will be a valuable resource for the S. pombe community. To make our data easily accessible to other researchers, we have created a supporting website at http://interactome-cmp.ucsf.edu/pombe2012/modules/ In addition to tools for searching for individual interactions, this site contains lists of functional modules identified from the data - groups of genes which exhibit highly similar genetic interaction profiles, indicating that they belong to common complexes or pathways. We foresee these functional module definitions being extremely useful for the functional annotation of uncharacterized genes, 320 of which are contained in our dataset. The associated paper "Hierarchical Modularity and the Evolution of Genetic Interactomes across Species" is available in Molecular Cell ( http://www.cell.com/molecular-cell/fulltext/S1097-2765(12)00444-3).

The site has been updated with an assortment of new features, datatypes, and bug fixes. More recent data, reflecting additions and changes through March 20, 2012, are now available on gene pages and in search results. The updated site features a Gene List Search that provides behavior equivalent to GeneDB's List Download. You can now type or paste lists into the Gene Systematic IDs and Gene Names filters, and use the Query History to combine a gene list search with other search options. For convenience, there is a direct link to a search page pre-configured to accept a list of systematic IDs available in the Find menu, on the Find page, and here: http://www.pombase.org/spombe/query/builder?filter=12 The Advanced Search also now offers: - options to search GO, FYPO, and other ontologies by term name or ID; - autocomplete for ontology term name search; - ability to search for genes in a region, such as centromeres or telomeres; - improved organization of filter selections. We have also fixed a Sequence Download error reported by some users, so that the "CDS", CDS + UTRs", and "CDS + UTRs + Introns" options now retrieve the correct sequences. In addition, numerous minor improvements have been made. Please send any questions or comments on the PomBase web site to us at .

I have been trying to do FISH using the protocol from the Nurse Lab Handbook. This protocol probably originated from JCS paper by Uzawa & Yanagida 1992. I am trying to detect a repeat sequence of 18bp (200-1000 copies per cell) using a Cy3-labeled oligo. So far I have not obtained specific signals, only diffusive fluorescence in the cells. I controlled for fixation and spheroblasting using immunofluorscence, and it seems that these procedures were fine. The thing I am concerned about is the efficiency of cell denaturation and hybridization condition, where I do not have a good control. Any tips will be deeply appreciated!

After successfully transforming the pON177, I got high concentration of sporulation and conducted the tetrad dissection on YES+G418 plate. I streaked the visible colonies on new EMM plate. However, I happened to notice the haploid h+ strain began to mate with each other. Did anyone encounter this problem before when dealing with pON177 plasmid? Is the mating caused by pON177 and how can I get rid of it? Also, did anyone have the sequence map of pON177 plasmid and can kindly provide it to me? Another problem I have is if there exists a plasmid that has the same function as pON177 (Mat1-M gene) but has a different auxotrophic marker.

Is it that you do not get asci or that the spores are inviable or something else? We cross a lot of strains that are difficult to cross, mostly due to nutrient sensing problems. While we used to use diploid selection with ade6-M210 and ade6-M216 alleles, we no longer do that. Here is our current method that works extremely well for us. 1. Make sure the two strains are freshly growing. 2. Mix 1-2 colonies worth of cells together in a small spot on an EMM plate that supports growth of both strains and let them grow together overnight. 3. Transfer the entire spot to an MEA plate at 30?C (first thing in the morning; our MEA contains 0.4% glucose because many of our strains lack fructose-1,6-bisphosphatase activity. I do not know if this may also help by providing energy for meiosis.). 4. Dissect on YES plates after 24 hours. Good luck.

Yes, you are right, our protocol is useful for looking at chromatin, but we do not isolate nuclei as such. I am sorry for the confusion. The reason for this confusion on my part is actually an interesting technical detail. We do a lot of nuclei isolation for chromatin analysis in S. cerevisiae (classical spheroplasting with zymolyase and then osmotic shock and centrifugation through Ficoll). At first we tried this for S. pombe, too. However, this way we observed a lot of DNA cleavage by endogenous nucleases. So we changed the protocol to spheroplasting/detergent, but in analogy to our S. cerevisiae work we keep saying in lab jargon that we do "nuclei preparation". Sorry about that. The spheroplasting/detergent protocol that we published gives much less endogenous cleavage. We are not sure why but guess that this protocol is less disruptive to some other compartment (lysosome, vacuole?) which may contain this endogenous nuclease. Any more specific answers are welcome.

And our protocol does not require the use of Zymolyase or other lytic enzyme. However, because our protocol employs a rather large commercial mortar grinder (Retsch RM100 or RM200), it is not suitable for nuclear isolation from small numbers of cells. In that case, if chromatin (rather than nuclei) will be sufficient, then the protocol published by Philipp would be best. I am currently working on editing instructional movies prepared by Bob Givens (who developed the nuclear isolation technique in my lab). These movies will show in detail all steps of our nuclear isolation procedure (and also of our high-molecular-weight DNA isolation procedure). As soon as my editing is complete and I have posted the movies to the Internet, I'll send another message to PombeList announcing that fact.

In two cycles of 2min each with 2min pause and we found quite efficient nuclei (85%) in solution as seen from DAPI staining. Since we are planning to isolate nuclei in large scale this method we have found far more efficient than Zymolase treatment. We have tried with 5g of frozen but this machine can be use to grind from 100mg to 40gm of cells depending on the size vials.

This all worked fine. Next, I transformed the exon containing the mutation into these strains and selected on 5FOA and used PCR to a) verify the intact locus and b) validate that URA4 was gone. This too worked fine. My next step is where things went awry: I PCRd up a fragment containing the intron-exon junctions at either end of the exon I had replaced to verify that a) recombination didn't screw things up and b) to verify the mutations within the exon by sequencing. Everything was clean except that the gene is wild type in all cases. I sequenced 3-4 clones of each of 3 mutations and in all cases I got back wild type. Is sister chromatid repair that good or is there something I'm missing? Any assistance would be greatly appreciated. Thanks!

You may need to first make sure that the homologous integration of the mutant allele is happening at a higher frequency than gene conversion of the disrupted allele to the wild type. How much homology did you have to either side of the mutation? What transformation protocol did you use?

This type of event can obscure finding what you want. One way we have gotten around this is in S. cerevisiae is to put a resistance marker, such as G418, next door to the URA3 insert. Transformants that have integrated the construct will be 5FOA resistant and still G418 resistant, whereas the mitotic recombinants will be G418 sensitive.

The suppressor transformed strains were starved of nitrogen (EMM-NH4Cl), but the FACS profile shows 15% of cells arrested in G1. The plasmid carries a uracil marker, so I thought may be the nitrogen from uracil may hinder the arrest. I would be pleased if you could clarify some of my doubts. 1. Is the experimental approach discussed above can be done at all, because I didnt find evidences of articles discussing the FACS profile of a strain that has been transformed with an ectopic plamsid in s.pombe.(pardon me if didnt give a proper serach) 2. I thought of alternative strategy where by my deletion strain has cdc25-22 background, but Im starting to worry whether transformation of this temerature sensitive strain works at all with lithium acetate protocol(growing @ 320C ) Even if plasmid can be transformed by electroporation, Whether arrest at higher temperature and release at lower temperature affect the plasmid expression in strains.

Alternatively, if you don't want to use mutant background, you might consider lactose-gradient synchronization . It is not as good as cdc25, but it is way better than nitrogen starvation.

It seems to me that all you did was to starve your cells for nitrogen and then look at the DNA distribution after awhile. And you were surprised that only 15% of the cells had a 1C DNA content. It appears to me that you did not use nitrogen starvation as a method to synchronize the cells, but I am not sure.

I intended to make a heterozygous sporulating diploid as a way to monitor chromosome loss upon the breakdown of the diploid. Using ade6 complementing alleles, the phloxin test for distinguishing diploids from haploids, I selected single colonies, resuspended at a low concentration and plated non-selectively (with the intent of replica plating for markers). However, after plating on low adenine plates, most colonies remained white and under a microscope all colonies (both white and pinks?!) remain diploid [longer, straighter asci and some have more than 4 spores]. Even after several days on EMM without selection. I will do the iodine stain test to confirm lack of sporulation. I have not tinkered with any mating or sporulation genes in these strains, and the mating type locus in parent cells is wild-type (one h+, one h-), so I assumed that the diploid would break down immediately. The haploid mutant parent strain is viable, though they do grow poorly. Does lack of sporulation in this context suggest that our mutation, though not absolutely necessary for viability, enhances viability? Will they break down eventually and/or is there a way to speed breakdown up, perhaps with glusulase? Please advise if there are other "standard" things that we should be doing that I am not aware of, primary literature that I should be reading, and/or suggestions for follow-up experiments.

It's essential to use YES as much as possible and confrim as you go along. Having a wild type cross alongside your mutant may help. "Breakdown" only occurs once they have sporulated. If what you have is just unsporulated diploids, glusalase will simply kill them.

Harris) Date: Fri, 9 Nov 2012 14:09:05 +0000 (GMT) Subject: [Pombelist] New data and new features on PomBase web site Message-ID: Dear pombe researchers, We are pleased to announce that we have updated both data and web site features for PomBase. Most importantly, we have added new data types, and upgraded the gene pages to display them. We have also added more annotations of existing data types. The new annotations include the first contributions to come in via the new community curation system, and we thank the researchers who are participating in the initial phase of community curation. New annotation types: - Phenotype annotations now use the Fission Yeast Phenotype Ontology (FYPO), and include allele details and experimental conditions. With FYPO, more detailed phenotypes can be described, and links between terms for related phenotypes support improved phenotype searches. - Many GO annotations now include "annotation extensions" that provide additional specificity. For example, extensions may capture the substrate of a catalytic activity, the cell cycle phase during which a function or process occurs, or any of several other types of supporting information for the annotation. For more information about annotation extensions, please see the news item on the PomBase web site (http://www.pombase.org/news/new-data-and-new-features-pombase-web-site). You can see these new data types on many gene pages, such as cdc2 (http://www.pombase.org/spombe/result/SPBC11B10.09) or pka1 (http://www.pombase.org/spombe/result/SPBC106.10). Additional new PomBase web site features include colour highlighting for retrieved sequences, transcript source data, and version data. A more extensive list of web site features is available in the news item (http://www.pombase.org/news/new-data-and-new-features-pombase-web-site).

S.pombe rhp6 is the homologue of S. cerevisiae RAD6 but the original S. pombe rad6 is the homologue of S. cerevesiae RAD18 and the name was changed to rhp18 to clarify that. Similarly S. pombe rad18 was renamed smc6 to avoid confusion. (The S. cerevisiae homologue was originally called rhc18 but strangely that name didn't catch on) The original mutants are deposited at the NCYC so by simplifying the names further you run the risk of newcomers to the field working on the wrong mutant. So while it would be much easier if everything was renamed it only really works when there is not already a history.

Comprehensive manual curation of the S. pombe literature is a primary goal of the PomBase project, and among the most important activities of the curation staff. Increasing numbers of new publications, and a large backlog of older papers, however, mean that complete literature curation will require input from the research community to supplement the efforts of dedicated professional curators. We have developed an online curation tool that provides an intuitive interface to annotate Gene Ontology details, single gene phenotypes, protein modifications and interactions. Multi-gene phenotype curation (e.g. double mutants) will soon be included as well. Participating in community curation is the fastest way to make your latest papers visible in PomBase, as the curators must now focus their efforts on curating older publications. Annotations made in the community curation system will also be rapidly disseminated to other databases (e.g. GenBank/ENA/DDBJ, UniProt, BioGRID and GO). We also invite you to evaluate existing annotations and create new annotations for partially curated publications (for example, many papers have no phenotype curation). If you would like to participate, please contact us via helpdesk at pombase.org, providing the PubMed ID of the publication(s) you would like to curate or update. We will send you a link and specific instructions. Finally, many thanks to our beta testers, who have successfully curated papers in the new system: Dominique Helmlinger (SAGA and tra1), Paul Russell (cnt5), Lynda Groocock (hrq1, Boddy lab), Juan Jaun Li (mcb1, Nurse lab), James Moseley (pil1), Martin Prevorovsk? (cbf11 & 12, Folk lab), Ursula Fleig (sos7), Sophie Martin (sec3), Peter Espenshade (nro1, ofd1), Juan Mata, Fransisco Navarro (wee1 and other wee, Nurse lab), Jacky Hayles, and especially Ryoko Mandeville (Nurse lab), for tackling a block of older papers from the Nurse lab.

We usually only include about 45 nt in the oligo for targeting when we are using a plasmid rather than targeting to the chromosome. The ura5 gene can also be used with 5FOA to find inserts to the plasmid. We have already done this a couple of times with no problems. Once you have replaced two ORFs with the ones you want, you can integrate this plasmid to either the ars1 locus or the lys7 locus on chromosome 1. Let me know if you would like this plasmid along with a strain carrying mutations in ura5, lys7, and leu1.

Many SGD tools and resources will be unavailable from Tuesday afternoon, November 27th, until Thursday, November 29th because we will be moving our entire computing operation to a newly opened data center on Stanford campus. This new data center will provides a very robust environment including a more secure facility, a faster network, and a backup generator in the event of a power failure. There is also plenty of room for expansion. All of these features were missing from our current computing facility. During the downtime you will be able to search the main SGD database at . However, many tools and pages, including the following, will be unavailable: Pathway Tools, YeastMine, Downloads/FTP, SPELL, GBrowse, Textpresso, and the wiki. We apologize for the inconvenience and thank you for your patience and understanding as we make this major improvement at SGD to enhance our service to research for the future.

The spot assay suggested by Professor Hoffman is a smart way to assess the mutants sensitivity to drug treatment. While I also want to check the cell viability treated by HU for different time period. For that aim, I hope to do exactly the same experiment as Professor Forsburg did in the Figure 1G in your recently published nice paper in Mol Cell Biol (Sabatinos SA et al, 2012). So could I have the detailed protocol that you did this experiment? Besides, I am worried that if I did not do it well for the NO HU control experiment in the similar way, my viability assay would be less convincing. Thanks in advance.

Thus, even though your method does not directly measure dividing cells, as long as the instrument, or your technique, is consistent with a high degree of reproducibility, you will get the same growth rate, regardless of what instrument/method you use. Each method has its inherited errors but these will be evened out over the course of a growth curve experiment. Thus the cheapest and fastest way of doing this is to use an instrument that measure the presence of "particles" in solution at a wave length of 600 nm, which is essential white visible light. A good old spectrophotometer can be used for this, obviously. We have found this portable single wavelength device for $700 USD (called Ultraspec 10, see attached) that does nothing but measure cell density. It is easy and simply to use and can be moved around from bench to bench. With all optical based measurement, the instrument shows the best linearity between OD of 0.1-0.6 or so so it is important to dilute the cell to be within this range to get an accurate measurement. Measuring cell density and colony number by plating are two slightly different experiments, although if one were to focus only on the "growth rate," the two methods should still yield the same results. In particular, the colony formation assay directly measure the number of cells that can form colonies, while the optical density method measures the balance between growth and death/dormancy. To properly plate the cell, one thing that we find it important is to make sure that the cells are evenly dispersed, as much as possible by vortexing vigorously, and EGTA/EDTA can be added to help, provided that they do not affect the growth of your cells. We also typically plate the cells in quadruplicate to better control variation. -- Best, Eric Chang N1130 (inside N1130)/x83519 From: , Babis > Date: Tuesday, December 18, 2012 7:44 AM To: Tomas Pluskal >, "pombelist at sanger.ac.uk" > Subject: Re: [Pombelist] Measuring cell concentration in liquid cultures Hi Tomas We use a Z1 coulter particle counter from Beckman Coulter. 20 ul of culture diluted in 10 or 20 ml of isotone buffer is a usual practice.

Actually, they are quite different experiments. We have plenty of mutants that will continue to "grow" (increase OD) for a few hours, but are essentially dying and unable to form colonies. If we are treating with a drug like HU that induces elongation, or a cdc mutant, the increase in OD may be reflecting increasing cell size and NOT increasing cell number. Or, cells may be dividing (increasing OD and cell number) but not be capable of forming colonies. If we do a viability assay, we always count them with a hemocytometer, never via OD.

In a balanced, steady-state culture I would not care to measure the number of particles (cells) per ml or the number of colony-forming units, but rather measure the rise in optical density. Up to an OD of about 0.3 (600 nm light) the rise in OD should be strictly exponential, as are the other parameters. At higher ODs the cells start sense nutrient changes and change morphology and metabolism, so the different parameters behave differently. If you wish to monitor your parameter under changing conditions, the picture is different. Then you need to measure exactly the parameter that you are looking for, whether it is cell size or viability or number of particles or a combination of different parameters. You can be sure that one parameter does not necessarily follow another. A simple example would be to shift a cdcts to the restrictive temperature, in which case you might see nothing on the OD curve, but cell size and number of particles and number of viable cells will dramatically increase/decline. Your original question was to measure the number of cells per ml. To do that you absolutely need a "particle counter" and you have got some suggestions. Make sure that you can detect your particles/cells separately from background noise in your system. The Coulter counters - or a similar orifice-based principle - usually work very well. You should also be aware that if you have a flow cytometer available, they might do the trick. Just check that the pump is stable enough for your measurements, i.e. do repeated experiments in the beginning.

Thus, even though your method does not directly measure dividing cells, as long as the instrument, or your technique, is consistent with a high degree of reproducibility, you will get the same growth rate, regardless of what instrument/method you use. Each method has its inherited errors but these will be evened out over the course of a growth curve experiment. Thus the cheapest and fastest way of doing this is to use an instrument that measure the presence of "particles" in solution at a wave length of 600 nm, which is essential white visible light. A good old spectrophotometer can be used for this, obviously. We have found this portable single wavelength device for $700 USD (called Ultraspec 10, see attached) that does nothing but measure cell density. It is easy and simply to use and can be moved around from bench to bench. With all optical based measurement, the instrument shows the best linearity between OD of 0.1-0.6 or so so it is important to dilute the cell to be within this range to get an accurate measurement. Measuring cell density and colony number by plating are two slightly different experiments, although if one were to focus only on the "growth rate," the two methods should still yield the same results. In particular, the colony formation assay directly measure the number of cells that can form colonies, while the optical density method measures the balance between growth and death/dormancy. To properly plate the cell, one thing that we find it important is to make sure that the cells are evenly dispersed, as much as possible by vortexing vigorously, and EGTA/EDTA can be added to help, provided that they do not affect the growth of your cells. We also typically plate the cells in quadruplicate to better control variation. -- Best, Eric Chang N1130 (inside N1130)/x83519 From: , Babis Date: Tuesday, December 18, 2012 7:44 AM To: Tomas Pluskal , "pombelist at sanger.ac.uk" Subject: Re: [Pombelist] Measuring cell concentration in liquid cultures Hi Tomas We use a Z1 coulter particle counter from Beckman Coulter. 20 ul of culture diluted in 10 or 20 ml of isotone buffer is a usual practice. The time required per sample is around 10 s but it requires flushing the system so probably timing could be same as in your case. No clogging.

In our lab we use the Sysmex CDA-500, a rather old machine that I believe is not produced anymore. We usually dilute 10 or 100 ul of cell culture into 10 ml of saline buffer, sonicate for 10 s and measure on the Sysmex. The measurement takes about 15 s, therefore the complete procedure takes about 30 s for one sample, if everything goes well. But the machine often gets clogged and requires cleaning. I would appreciate to hear about your experience using other machines, particularly if anyone knows a good cell counter especially suitable for pombe cultures in terms of reliability and high throughput.
