mus306D1 mutants have a similar frequency of single-strand annealing repair (SSA) compared to controls in a P{wIw.FRT} hemizygous assay to study DNA double-stranded break repair when assayed at 32oC, but show a reduced SSA frequency compared to controls when assayed at 38oC.
Excision repair capacity and post-replication repair capacity are normal.
A partial deficiency in the excision repair of pyrimidine dimers originally observed in this mutant is now attributed to the presence of a secondary phr mutation, phrmus306-D1.
Larval survival is sensitive to methyl methanesulfonate.
Flies are not sensitive to X rays.
Larval survival sensitive to exposure to methyl methanesulfonate. Displays hypermutability to alkylating agents; defective both in alkylation and UV excision repair pathways.
Homozygotes fertile. Partially excision repair deficient.
Sensitive to 0.075% methyl methanesulfonate. Not sensitive to 0.008% HN2.
mus306D1/mus306D1 has no effect on the frequency of X-Y chromosome nondisjunction seen in Df(1)X-1-53B males.
