Subject: Irick and Cherbas Ly region complementation groups From: Kevin Cook, Bloomington Drosophila Stock Center Subject: Ly region complementation groups of Holly Irick and Peter Cherbas A screen for EMS-induced mutations that fail to complement Df(3L)BK10 was made by Holly Irick in Peter Cherbas' lab in 1988. The Df(3L)BK10 chromosome was marked with Ly1 (=Df(3L)Ly); consequently, two lethal complementation groups were defined in the 70A region which Irick and Cherbas called Ly-1 and Ly-2. Alleles include: Complementation group Allele Ly-1 E1 E2 E53 E54 E58 E64 E69 Ly-2 E70 All mutations were induced in a red1 e1 chromosome.
