Subject: Re: abstract from 33rd ann Dros Res conference, 1992 Dear Dr Green, I apologise for getting back to you at such a later date but curation of the 33rd ADRC abstract book has brought me back to the original abstract I queried you about and I have remembered a question I should have asked the first time round. Our policy, now, is never to curate the posters from which an abstract is based. This is because the information from the poster is never published as the poster itself, but as a subsequent publication which will get curated by FlyBase and therefore be entered into the database. Before this descision was made Prof. M. Ashburner made a practice of recording gene names from each poster to which the abstract could be referenced. Consequently we now have your reference: \*x FBrf0055320 == Green et al., 1992, A. Conf. Dros. Res. 33: 48 against a series of genes and alleles and I have no way of knowing by which means they arrived there. These genes and alleles have very little information except what was possibly stated on your poster. I realise this was a while ago but have you published anymore information about the following genes so they can be correctly referenced and be more fully curated? \*a fas \*A fasG5 \*x FBrf0055320 == Green et al., 1992, A. Conf. Dros. Res. 33: 48 \*a old \*e optic lobe defective \*b 2-56 \*c 42E3--43C3 \*x FBrf0055320 == Green et al., 1992, A. Conf. Dros. Res. 33: 48 \*a shg \*A shgG137 \*x FBrf0055320 == Green et al., 1992, A. Conf. Dros. Res. 33: 48 Any help would be greatly appreciated, Happy holidays Eleanor Whitfield, on behalf of FlyBase. Your information concerning the enhancer trap was marvellous, Thanks again. Subject: Re: abstract from 33rd ann Dros Res conference, 1992 HAPPY NEW YEAR, ELEANOR! I was celebrating my recent defense, and I have been on vacation, so I just got your e-mail. Sorry about the delay. Here is the scoop on the genes you asked me about. optic lobe defective: we were calling the P-element tagged sine oculis locus optic lobe defective, because we hadn't realized that the locus was actually sine oculis, yet. In a later poster (34th, I think) the locus had been renamed and called absent minded (ami)(this reflected a collaboration which had been started and we took over the name the other group had for it). We changed the locus name to sine oculis as soon as we figured it out. fas: faint sausage. This gene is being cloned and sequenced in our lab and a paper will be submitted probably by August of 1995. Subsequent queries should be made to arne lekven .. since he is the one who is cloning it. I believe he has published one other abstract, but no other papers utilizing this mutant. shg: shotgun. This gene is also being cloned and sequenced in our lab. There has been one further Dros Conf poster, by Tepass, I think. Anyway, you should make inquiries to Ulli Tepass .. since he is the person who will eventually clone this gene. Both fas and shg were isolated by Nusslein-Volhard,Weischaus, etc in THE BIG F2 screen. I am sorry I could not be more helpful on these two loci. Ulli and Arne will probably be better able to fill you in. Have a nice day, Patti
