All of the Azorhizobium, Bradyrhizobium, and Rhizobium genes known to be involved in the development of nitrogen-fixing legume root nodules are genes that code for proteins. Here we report the first exception to this rule: the sra gene; it was discovered during the genetic analysis of a Bradyrhizobium japonicum Tn5 mutant (strain 259) which had a severe deficiency in colonizing soybean nodules. A DNA region as small as 0.56 kb cloned from the parental wild type restored a wild-type phenotype in ...[more]
