Subject: Help FlyBase - P1749 Dear Dr. Volk, I am a curator of FlyBase working at the Cambridge, England, site with Prof. M. Ashburner. FlyBase minimally curates information from the ADRC abstract book and we pay particular attention to new genes/alleles etc that are described. Your abstract (17B) discusses a new gene, P1749. We have noticed that P1749 is the Bloomington stock number for l(3)10567 (at cytological location 64F). Is this the line you used or is P1749 something completely different? If it is something different could you please tell me more. HELP!! Eleanor Whitfield FlyBase Dear Eleanor, Yes P1749 is the P element from the Spardling collection l(3)10567 which is mapped to 64F. We confirmed this localization by chromosomal in situ with rescued genomic DNA. Best regards, Talila.
