traG Gene Is Conserved across Mesorhizobium spp. Able to Nodulate the Same Host Plant and Expressed in Response to Root Exudates

Genomic context analysis of T4SS, T3SS and symbiosis genes in the symbiotic islands/regions of the genomes of several mesorhizobia strains. This analysis includes the genomes of symbionts of three different host plants, namely Cicer arietinum, Biserrula pelecinus, and different Lotus species. The tra/trb and virB/virD4 complexes identified in the mesorhizobia strains and studied in this work present similarities with the T4SSe-like and T4SSb/c-like of Ensifer strains, according to [21]. Slash sign (/) indicates a random genetic distance.
