山蚂蝗慢生根瘤菌的遗传多样性及系统发育

Objective]Genetic diversity and phylogeny of bradyrhizobial strains associated with Desmodium spp.in subtropic and temperate regions of China were analyzed.Methods] We studied 29 desmodia isolates from different regions with BOX-PCR fingerprinting and multilocus sequence analysis(nifH,nodC and recA gene) to describe the genotypic characteristics and phylogenetic relationships.Results] We achieved 25 genotypes with BOX-PCR genomic fingerprinting analysis,indicating that the tested strains had a great dive...
