Mutants do not show sensitivity to colchicine, griseofulvin or vinblastine.
Homozygous larvae show a significantly higher sensitivity to analgin, amidopirine and antipirine compared to heterozygotes. The relative sensitivity of the homozygotes increases as the concentration of analgin, amidopirine or antipirine is increased.
Early and late larvae show extremely high sensitivity to the lethal action of methyl methanesulfonate and UV light. The rate of excision of UV-induced pyrimidine dimers is significantly lower than wild-type in primary embryonic cell cultures. These cells show a 4-5 fold decrease in UV-specific endonuclease activity.
Larvae are supersensitive to methyl methanesulfonate.
