TL;DR: The nitrosoamides tested had a much higher mutagenic efficiency than X-rays, i.e. at the same level of induced mutations they caused less sterility, and the nitrosoureas tested were active, whereas only methyl and ethyl derivatives of nitrosogunidines were.
Abstract: The mutagenic activities of five 1-alkyl-1-nitrosoureas and six 1-alkyl-3-nitro-1-nitrosoguanidines were tested and compared on Arabidopsis thaliana . All the nitrosoureas tested were active, whereas only methyl and ethyl derivatives of nitrosogunidines were. There was a tendency for the mutagenic effectiveness to decrease with increasing number of C-atoms in the alkl group. The nitrosoamides tested had a much higher mutagenic efficiency than X-rays, i.e. at the same level of induced mutations they caused less sterility. The possible reasons for the activity of nitrosoguanidines in Arabidopsis and their lack of mutagenic activity in barley are briefly discussed.
