PublicationArticle Histidine sensitive variant of the blue-green alga Nostoc muscorum: Response to corepressors of histidine biosynthesis(Springer-Verlag, 1979) Pramod K. YadavaA model has been proposed to account for growth inhibition by L-histidine in a variant strain of Nostoc muscorum. This strain has been characterized for its response to 3-amino-1,2,4-triazole and 1,2,4-triazole-3-alanine known to act as false corepressors of the histidine biosynthesis genes. The histidine sensitive strain retained its sensitivity to triazole alanine while the inhibitory effects of aminotriazole were much reduced indicating a change in regulation of his genes. The probable interactions between nif and his genes in cyanobacteria (blue-green algae) have been discussed. © 1979 Springer-Verlag.
