pubmed-article:6318104 | pubmed:abstractText | Diethyldithiocarbamate and carbon monoxide markedly inhibited the frequency of embryonic and chlorophyll mutations induced by the metabolism-requiring mutagen dimethylnitrosamine in the higher plant Arabidopsis thaliana. In contrast, the monoamine oxidase substrates, tryptamine, benzylamine and 2-phenylethylamine, had no such effect. The mutagenicity of a direct-acting mutagen, N-methyl-N-nitrosourea, was not altered by these inhibitors or substrates. | lld:pubmed |
