We identify three SDEs that inhibiting host defence from Candidatus Liberibacter asiaticus psy62, which is an important supplement to the pathogenesis of HLB. Candidatus Liberibacter asiaticus (CLas) is the main pathogen of citrus Huanglongbing (HLB). 38 new possible sec-dependent effectors (SDEs) of CLas psy62 were predicted by updated predictor SignalP 5.

Here we used transposon (Tn) mutagenesis with the aim to identify genetic elements required for EPS biosynthesis in USDA110.

- 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.
