摘要: Abstract This study determined the extent of horizontal gene transfer among rhizobial genera in Core Cape Subregion (CCR) South Africa and reconstructed ancestral symbionts legumes. Phylogenies two chromosomal genes (16S rRNA recA) one nodulation (nodA) rhizobia, isolated from diverse legumes CCR, were using Bayesian Maximum Likelihood techniques. A cophylogenetic analysis was used to test for congruence between nodA phylogenies. Five rhizobia (Bradyrhizobium, Burkholderia, Mesorhizobium, Rhizobium Sinorhizobium) studied. phylogeny matK rbcL DNA sequences it reconstruct their methods. The mostly incongruent with that nodA, indicating potential inheritance latter. Mesorhizobium had different evolutionary histories counterparts other parts globe. Burkholderia as CCR Evidence co-diversification observed this highlights a role legume-rhizobia interaction high diversity CCR. Finally, availability compatible competitive ability are discussed possible drivers lack shared Fynbos biome Kwongan Australia.
