摘要： Mikania micranthais a noxious invasive plant causing enormous economic losses and ecological damage. Soil microbiome plays an important role in the invasion process ofM. micrantha, while little is known about its rhizosphere microbiome composition and function. In this study, we identified the distinct rhizosphere microbial communities ofM. micrantha, by comparing them with those of two coexisting native plants (Polygonum chinenseandPaederia scandens) and the bulk soils, using metagenomics data from field sampling and pot experiment. As a result, the enrichment of phosphorus-solubilizing bacteriaPseudomonasandEnterobacterwas consistent with the increased soil available phosphorus inM. micrantharhizosphere. Furthermore, the pathogens ofFusarium oxysporumandRalstonia solanacearumand pathogenic genes of type III secretion system (T3SS) were observed to be less abundant inM. micrantharhizosphere, which might be attributed to the enrichment of biocontrol bacteriaCatenulispora,Pseudomonas, andCandidatus Entotheonellaand 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 ofM. micranthalargely enhances its adaptation and invasion to various environments.
