Mutagenicity of a bipyridylium herbicide in an N2-fixing cyanobacterium Nostoc muscorum
Abstract The herbicide diquat (1,1′-ethylene-2,2′-bipyridylium ion) is toxic and lytic to Nostoc muscorum. A reverse mutation (from het − nif − auxotrophy to het + nif + prototrophy), a forward mutation (for streptomycin [St]-resistance), and an auxotrophic mutation (carbon-auxotrophy through methylamine [MA]-resistance) have been obtained with a dose of diquat permitting about 20% or 50% survival. Similar mutation frequencies were obtained through induction with MNGG (N-methyl-N′-nitro-N-nitrosoguanidine).
