Chromosomal gene controlling symbiotic nitrogen fixation in Rhizobium meliloti L5-30.
Auxotrophic Rhizobium meliloti strain RM 246 carries two independent mutations: in the biosynthesis of cysteine (cys) and symbiotic nitrogen fixation process (fix). These two mutations were mapped by transduction between his-240 and ade-4 markers. Cotransduction frequencies show the following order of genes: his-240 fix-1 cys-246 ade-4.
