The Rhizosphere Microbiome of Provides Insight Into Adaptation and Invasion.

is a noxious invasive plant causing enormous economic losses and ecological damage. Soil microbiome plays an important role in the invasion process of , while little is known about its rhizosphere microbiome composition and function. In this study, we identified the distinct rhizosphere microbial communities of , by comparing them with those of two coexisting native plants ( and ) and the bulk soils, using metagenomics data from field sampling and pot experiment. As a result, the enrichment of phosphorus-solubilizing bacteria and was consistent with the increased soil available phosphorus in rhizosphere. Furthermore, the pathogens of and and pathogenic genes of type III secretion system (T3SS) were observed to be less abundant in rhizosphere, which might be attributed to the enrichment of biocontrol bacteria , , and and polyketide synthase (PKS) genes involved in synthesizing antibiotics and polyketides to inhibit pathogens. These findings collectively suggested that the enrichment of microbes involved in nutrient acquisition and pathogen suppression in the rhizosphere of largely enhances its adaptation and invasion to various environments.
