Mutagenic effects of sodium azide in Drosophila melanogaster

Abstract The mutagenic effects of sodium azide (NaN 3 ) were studied at low pH in male Drosophila melanogaster using the sex-linked recessive-lethal test. No significant increase in the mutation frequency was observed after abdominal injection of azide solutions buffered at either pH 3.8 or 4.6. However, a weak mutagenic effect was noticed in the flies fed for 3 days on 0.1 mM azide (pH 4.6) solution.
