The ability of L-cysteine to inhibit azide-metabolite synthesis and mutagenicity is investigated in Salmonella typhimurium TA1530 and cys E6 strains. L-cysteine specifically inhibits the synthesis of the mutagenic azide metabolite as other compounds

To utilize and exploit pollen for in situ mutagen monitoring, screening and toxicology, the range of genetic traits in pollen must be identified and analyzed. Traits that can be considered include ornamentation, shape and form, male sterility viabili

A scheme that employs a cation-exchange column and high-pressure liquid chromatography (HPLC) is devised to isolate and process large quantities of azide metabolite produced by S. typhimurium TA1530 strain. The mutagenic metabolite adheres strongly t

The ability of Arabidopsis, Drosophila and Neurospora to convert azide to its mutagenic metabolite was investigated. Cultures of these organisms all contained significant levels of O-acetylserine sulfhydrylase activity. Extracts from each organism pr
