The following information was provided by Alan Michelson (National Heart, Lung and Blood Institute) and Talila Volk (Weizmann Institute). Alan Michelson made a UAS construct of taxi/Delilah (FBgn0263118) and shared his stocks with Talila Volk. Consequently, P{UAS-dei.M} (FBtp0021478) and P{UAS-dei.V}(FBtp0065563) are actually the same construct. The entries should be merged under P{UAS-dei.M}. -- Kevin Cook, Ph.D. Bloomington Drosophila Stock Center http://flystocks.bio.indiana.edu
