ABSTRACT
The distribution of rhcRST and rhcJ-C1 fragments located in different loci of the type III secretion system (T3SS) gene cluster in the peanut-nodulating bradyrhizobia isolated from Guangdong Province, China was investigated by PCR-based sequencing. T3SS was detected in approximately one-third of the peanut bradyrhizobial strains and the T3SS-harboring strains belonging to different Bradyrhizobium genomic species. Diverse T3SS groups corresponding to different symbiotic gene types were defined among the 23 T3SS-harboring strains. The same or similar T3SS genes were detected in different genospecies, indicating that interspecies horizontal transfer of symbiotic genes had occurred in the Bradyrhizobium genus.
