Seven rhizobia and five non-rhizobia rhizobacteria strains were used to determine how plant-microbe interactions affect the competition between invasive Lespedeza cuneata and its native relative, Lespedeza virginica. Different rhizobia strains showed different impacts on the competition between L. cuneata and L. virginica. A relatively fast-growing Mesorhizobium strain and one of the Rhizobium strains showed low nodulation rate and no significant effect on the two plant species. All three Bradyrhizobium strains and two of the Rhizobium strains showed positive effects on the growth of L. cuneata, but they do not have the effect on the growth of L. virginica, so I conclude that invasive L. cuneata benefited more from the plant-rhizobacteria symbiosis relationship. This result emphasizes the influence of belowground interactions on the aboveground community. The finding that rhizobacteria mutualism can support the invasion of L. cuneata provides another perspective to invasion studies of L. cuneata.
