Isolation and characterization of an olfactory mutant in Drosophila with a chemically specific defect.

RESUMO
A Drosophila mutant was isolated and shown to exhibit defective response to the chemical odorant benzaldehyde in two distinctly different behavioral assays. The defect exhibited chemical specificity: response to three other chemicals was normal. The mutant also showed abnormalities in pigmentation and fertility. Genetic mapping and complementation analysis provide evidence that the olfactory, pigmentation, and fertility defects arise as a result of a lesion at the pentagon locus. The specificity of the olfactory defect suggests the possibility that the mutation may define a molecule required in reception, transduction, or processing of a specific subset of chemical information in the olfactory system.
