Ecological assembly process of microbial communities and neutral community model fitting of ASV in different niche subcommunities. Zero-model analysis of bacterial and fungal (a) communities under degradation membrane (d), βNTI indexes of bacterial and fungal communities in bulk soil, rhizosphere, and root surface and under degradation membrane (b, c, e, and f). Neutral model fitting of bacterial (g-j) and fungal communities (k-n) in different ecological niches and root ecosystems. NRS represents bulk soil; RS represents rhizosphere; RI represents endosphere.
