Abstract: Fungal communities are important drivers of soil physicochemical processes, and some fungal genera have the ability to inhibit Cd pollution, to ensure the quality and safety of food.An important grain production area, County A in China was selected in this study.50 paddy fields were randomly selected for sampling to obtain soil Cd pollution data.The basic physical and chemical properties and heavy metal content of the soil were examined in laboratory.Soil fungal communities were detected using high-throughput sequencing technology.By using the Geological Accumulation Index (GI) and Nerome Comprehensive Index (NI), the pollution level of Cd in soil was evaluated.It was showed that there were two pollution levels in this study area, i.e.severe pollution (IV, NI>3) and moderate pollution (III, 2<NI ≤ 3).The research results indicated that: (1) The fungal community richness index Sobs, Chao and Diversity index Shannon, Invsimpson were significantly higher for Cd severe pollution, than those with a moderate pollution level.(2) The relative abundance of four fungal phyla, including Ascomycota, was significantly positively correlated with Cr, Hg, Pb, As, and Hg contents in soil samples with a severe Cd pollution level.Meanwhile, five fungal genera including Penicillium were significantly positively correlated with Cu, Pb, Hg, and Ni contents.(3) The functional abundance of fungal communities in soil environments heavily polluted by Cd, including pathological symbiotic, saprophytic symbiotic, and pathological saprophytic symbiotic transition, was significantly higher than those in the moderately polluted areas at a p<0.05 level.These results indicated that there were still certain heavy metal tolerant bacterial strains that could play a role in soil energy cycling and effectively degraded heavy metal toxicity in Cd polluted soil environments.
