Dear Dr Wismar, I am currently curating your paper for FlyBase: Wismar et al., 2000, Dev. Biol. 226(1): 1--17 Does the EMS allele wocrdg the same allele as the single EMS allele mentioned in your abstract from 13th EDRC meeting in Crete? Wismar et al., 1993, Europ. Dros. Res. Conf. 13: Poster I6 Best wishes, Chihiro \--------- Subject: woc allele Dear Chihiro, The allel woc rgl is not the same as the one in the abstract of 1993 which was found in a P-element mutagenesis (not EMS allele as you wrote) but does not contain a P-lac W insertion. This allel is now called woc st1 as mentioned in materials and methods. Sincerely Jasmine \--------- Subject: Re: woc allele Dear Jasmine, Thanks for your reply. So if I understand you correctly, the wocst1 allele is one of the nine woc alleles found 'during an 'enhancer trap' mutagenesis' as mentioned in the 1993 abstract. Is this right? In the next sentence 'One is EMS induced', suggests that you also had at that time another single EMS induced woc allele. Does this still exist? Have you given it a name? The reason I ask is that in looking through our current records, up until your recent paper, we only had one woc allele recorded \- woc1. It seems that this was created by us in 1993, based on the statement that describes a single unnamed allele i.e. 'One is EMS induced'. The name was given arbitrarily by us at the time (we no longer name unnamed alleles in this way), I would like to change it to a name assigned by you. Do you have one I can used? Thanks Chihiro \------- Subject: Re: woc allele Dear Chihiro, I know it is confusing with the woc alleles. We have one EMS induced allel called woc rgl (Dev. Bio. 226, 2000) this was the one mentioned as 'one is EMS induced' in 1993. All the phenotype described in this abstract deals about the sterile alleles thus I thought you have been talking about these alleles in your letter. Sorry for this . The nine alleles from the enhancer trap mutagenesis seem to be just one allele as all the PlacW insertions have been at different places on the third chromosome. Separating the mutation (not yet identified on sequence level) from the PlacW insertions by crossing over all the 'alleles' show the same phenotype and have white eyes. Thus we suppose that the nine alleles are just one allele which we called woc st1, but this has to be confirmed by sequence analysis (on the way). I hope that now the situation is clear otherwise ask again. Sincerely Jasmine
