Soil nutritional status and biogeography influence rhizosphere microbial communities associated with the invasive tree Acacia dealbata

Abstract Invasiveness and the impacts of introduced plants are known to be mediated by plant-microbe interactions. Yet, the microbial communities associated with invasive plants are generally poorly understood. Here we report on the first comprehensive investigation of the bacterial and fungal commu...
