Abstract

Several chlorate-resistant mutants of were isolated and analysed; all were affected in nitrate assimilation. Nine loci were recognized by complementation analysis and these appear to be equivalent to the (nitrate reductase structural gene), (control locus) and seven loci (responsible for the biosynthesis of a cofactor for nitrate reductase) of . The organization of the nitrate assimilation genes appears to be similar in both organisms, even to the extent of having contiguous genes coding for the nitrate and nitrite reductase enzymes.
