AI Article Synopsis
- The study analyzed the presence of specific fragments (rhcRST and rhcJ-C1) in the type III secretion system (T3SS) gene cluster of peanut-nodulating bradyrhizobia from Guangdong Province, China using PCR sequencing.
- About one-third of the bradyrhizobial strains were found to contain the T3SS, which varied among different genomic species.
- The research defined multiple T3SS groups linked to different symbiotic gene types and suggested that there has been horizontal gene transfer between species in the Bradyrhizobium genus.
Article 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.
