摘要： Kudzu (Pueraria lobata) is an important medicinal plant, which can associate with rhizobia for nitrogen fixation. The mutualistic symbiosis between rhizobium and kudzu is not well understood, but it is necessary to fully utilize kudzu. Nodules and rhizosphere soils collected from 16 sampling sites were characterized based on phylogenetic analyses of the rpoB gene; 16S rRNA gene; the housekeeping genes SMc00019, truA, and thrA; and the symbiotic genes nodA and nifH. The relationships between biogeographic pattern, nitrogenase activity, and environmental factors were studied. Results indicated that a clear biogeographic pattern of rhizobial communities in the kudzu rhizosphere existed in southern China; latitude and soil pH were found to be the most important factors affecting the biogeographic pattern. Bradyrhizobium diazoefficiens and Bradyrhizobium erythrophlei were the dominant species in kudzu rhizosphere. The symbiotic rhizobia in kudzu nodules mainly belonged to B. lablabi, B. elkanii, B. pachyrhizi, and B. japonicum. Nitrogenase activities in the nodules of kudzu in the Jiangxi sampling region were significantly higher than those in the Guangxi and Hunan sampling regions, and they were significantly negatively correlated to pH and exchangeable Ca. These results constitute the first report of the existence of symbiotic genes in kudzu bradyrhizobia, which are similar to those in B. elkanii and B. pachyrhizi. Our findings could improve the understanding of kudzu-rhizobium symbiosis and could advance the application of rhizobial inoculation in medicinal legumes in terms of increasing the content of active ingredients.
