[Diversity and Functional Characteristics of Fungal Communities and Influencing Factors in Typical Paddy Fields of China].
To investigate the structure, diversity, and function of different paddy soil fungal communities and the factors affecting them in typical paddy cropping areas in China, five typical Chinese paddy soils were selected in this study, and the composition and diversity of soil fungal communities were comparatively analyzed using high-throughput sequencing technology and functionally predicted using the FUNGuild microecological tool. The results showed that: ① The fungal community diversity of soil samples from Heilongjiang (HLJ) was significantly lower than that of the other four regions (P<0.05); the highest fungal community richness was found in paddy soils from Yunnan (YN), which was significantly higher than that of the other regions (P<0.05); and the soil samples from Hainan (HN), Jiangxi (JX), and Shandong (SD) were relatively close to each other. The highest average relative abundance at the level of the five typical paddy phyla was Ascomycota, and the genus with the highest average relative abundance was Tausonia. ② Fungi had the largest proportion of saprophytic trophic types, and their corresponding environmental functions were stronger. ③ The species abundance of soil fungi was highly significantly correlated with soil TP, EC, and BD (P<0.01), and redundancy analyses also showed that soil TP was the main driver of the fungal community as well as the saprophytic functional taxa. The above results showed that the soil fungal community diversity and structure varied greatly among samples, and the relative abundance of fungal genera was affected by soil physical and chemical properties and altered the fungal community structure in paddy fields. The development of this study will provide theoretical references for the sustainable management based on fungal diversity and function of paddy fields.
