SUMMARY: Five loci have been identified in Mutants at these loci were chlorate resistant and able to utilize nitrate. The locus was closely linked to, and may be allelic with, , a regulatory gene controlling induction of the nitrate reductase pathway. The locus was linked to, but distinct from, the gene coding for a molybdenum-containing cofactor. The and loci were unlinked to any known gene affecting nitrate reduction. The locus was clearly linked to the gene coding for the nitrate reductase enzyme. Mutants of and had low but detectable levels of nitrate reductase activity; these mutations may be leaky alleles of nitrate reduction genes. mutants had normal nitrate reductase activity, and may be altered in nitrate uptake.
