Arbuscular mycorrhizal fungi promote functional gene regulation of phosphorus cycling in rhizosphere microorganisms of Iris tectorum under Cr stress
Original language description
The mutualistic symbiotic system formed by clumping arbuscular mycorrhizal fungi (AMF) and plants can remediate heavy metal -contaminated soils. However, the specific mechanisms underlying the interaction between AMF and inter -root microbial communities, particularly their impact on organic phosphorus (P) cycling, remain unclear. This study investigated the gene regulation processes involved in inter -root soil phosphorus cycling in wetland plants, specifically Iris tectorum , following inoculation with AMF under varying concentrations of chromium (Cr) stress. Through macro-genome sequencing, we analyzed the composition and structure of the inter -root soil microbial community associated with Iris tectorum under greenhouse pot conditions. The results demonstrated significant changes in the diversity and composition of the inter -root soil microbial community following AMF inoculation, with Proteobacteria, Actinobacteria, Chloroflexi, Acidobacteria, and Bacteroidetes being the dominant taxa. Under Cr stress, species and gene co -occurrence network analysis revealed that AMF promoted the transformation process of organic phosphorus mineralization and facilitated inorganic phosphorus uptake. Additionally, network analysis of functional genes indicated strong aggregation of ( pstS, pstA, pstC, TC.PIT, phoR, pp-gppA ) genes, which collectively enhanced phosphorus uptake by plants. These findings shed light on the inter -root soil phosphorus cycling process during the co-remediation of Cr -contaminated soil by AMF- Iris tectorum symbiosis, providing valuable theoretical support for the application of AMF-wetland plant symbiosis systems to remediate heavy metal -contaminated soil.
