title: Genetic mapping of leucine and isoleucine-valine loci in Rhizobium japonicum.
abstract: Leucine and isoleucine-valine loci have been mapped in Rhizobium japonicum. Transformation analysis suggests a common pathway for isoleucine-valine biosynthesis. Three-point reciprocal crosses indicated that all the leucine loci are not genetically linked.
