Rhizosphere Keystone Microbiomes Promote Invasive Plant Growth under PLA and PVC Microplastic Stress: A Comparative Study with Native Species

. These microbes were associated with more interconnected and stable microbial networks, which may have enhanced invasive plant tolerance to microplastic-induced stress. Our results suggest that microplastics can reshape rhizosphere microbial communities in ways that have profound implications for ecological restoration and invasive species management. Future research should experimentally validate the functional roles of these enriched microbial taxa in promoting plant resilience under environmental stress.
