Subject: FlyBase query Dear Dr. Orr-Weaver, I am curating your paper for FlyBase: Lee et al., 2001, Genetics 158(4): 1545--1556 In the last paragraph of the Results you say that 'APC5' does not affect png. You reference Spradling et al., 1999, Genetics 153(1): 135--177 for APC5. However, I can't find APC5 in that paper and we have no record of an 'APC5' in FlyBase. Could you tell me which P-element 'ACP5' corresponds to so I can work out which gene it is, thanks, Gillian \-------------------------------------------------------------- Gillian Millburn. FlyBase (Cambridge), \-------------------------------------------------------------- Subject: FlyBase curation query Dear Gillian, I'm a postdoc in Terry Orr-Weaver's lab, and she asked me to respond to your question about our recent Genetics paper. I obtained the information about APC5 from a poster at the 2001 Annual Drosophila Research Conference in Washington, D.C.: Poster \#145A Mutations in ida cause aneuploidy and defects in late cell cycle events. A.M. Bentley, B.C. Williams, M.L. Goldberg, A.J. Andres. The name 'ida' is short for 'imaginal discs arrested.' The P line that I used was l(3)63FbB4. (I obtained the name of the P line from the poster.) The Bloomington stock# is 5167. I just looked up that stock# on the Bloomington page to double-check my facts, and it is now listed as idaB4. The 2001 fly meeting abstract book lists 'ida' in the index, but not APC5, so it could have been easily missed. I hope that clarifies things. Let me know if you need more information. Sincerely, La
