Rhizosphere microbes are important for plant tolerance to various soil stresses. Rice is the most aluminum (Al)-tolerant small grain cereal crop species, but link between rice Al and rhizosphere microbiota remains unclear. This study aimed investigate microbial community structure of aluminum-sensitive Al-tolerant varieties in acid sulfate under liming non-liming conditions. We analyzed biomass mineral element contents plants as well chemical properties (archaea, bacteria, fungi) communities bulk samples. The results showed that genotype grew better was able take up more phosphorus from than Al-sensitive genotype. Liming main factor altering diversity structure, followed by effects. In absence effects, genotypes shifted bacteria fungi, which accounted observed variation biomass. recruited specific bacterial fungal taxa (Bacillus, Pseudomonas, Aspergillus, Rhizopus) associated with solubilization growth promotion. co-occurrence network complex conclusion, has genotype-dependent effects on tolerance. Aluminum-tolerant recruit taxa, especially phosphorus-solubilizing microorganisms, networks, may enhance soil.
