Soil fungal community characteristics vary with bamboo varieties and soil compartments

Abstract

Soil fungi play an important role in nutrient cycling, mycorrhizal symbiosis, antagonism against pathogens, and organic matter decomposition. However, our knowledge about the community characteristics of soil fungi in relation to bamboo varieties is still limited. Here, we compared the fungal communities in different soil compartments (rhizosphere vs. bulk soil) of moso bamboo (Phyllostachys edulis) and its four varieties using ITS high-throughput sequencing technology. The fungal α diversity (Shannon index) in bulk soil was significantly higher than that in rhizosphere soil, but it was not affected by bamboo variety or interactions between the soil compartment and bamboo variety. Soil compartment and bamboo variety together explained 31.74% of the variation in fungal community diversity. Soil compartment and bamboo variety were the key factors affecting the relative abundance of the major fungal taxa at the phylum and genus levels. Soil compartment mainly affected the relative abundance of the dominant fungal phylum, while bamboo variety primarily influenced the dominant fungal genus. Network analysis showed that the fungal network in rhizosphere soil was more complex, stable, and connected than that in bulk soil. A FUNGuild database analysis indicated that both soil compartment and bamboo variety affect fungal functions. Our findings provide new insights into the roles of both soil compartments and plant species (including variety) in shaping soil fungal communities.

“…Consequently, meticulous selection of soil sampling methods emerges as a pivotal determinant in unraveling the complexities of soil fungal ecology (Huang et al, 2020). Disparate sampling techniques may yield divergent insights into fungal community structure and abundance, underscoring the necessity of standardized protocols to ensure data comparability and robustness (Guo et al, 2023).…”

Plant root secretions provide carbon substrates, including primary and secondary metabolites, utilized by fungi(Jones et al, 2004;Broeckling et al, 2008;Guo et al, 2023). This suggests that different plant varieties may in uence the resident soil fungal community through variations in their root exudate composition.…”

“…This aligns with prior research demonstrating the ability of diverse plant species to shape fungal communities via root secretions. The observed differences in fungal communities associated with different tomato varieties potentially stem from this mechanism(Jones et al, 2004;Broeckling et al, 2008;Guo et al, 2023).…”
