Determinants of rhizosphere community structure: The role of root traits and soil properties in coniferous plantations
No full textRoots serve as essential linkages between aboveground and belowground communities and play a key role in maintaining multiple ecosystem functions. Soil communities consist of plant roots and their associated mycorrhizal fungi, microorganisms such as bacteria and fungi, and fauna across a wide range of sizes and trophic groups, all interconnected within complex food webs. However, our understanding of how tree root systems mediate the composition and diversity of soil biota remains limited. This study aimed to determine the effects of the root systems of four coniferous tree species and the soil properties they mediate on soil bacterial, fungal, and nematode communities. We collected soil and root samples from monocultural coniferous stands; Pinus densiflora (Pine), Larix kaempferi (Larch), Chamaecyparis obtusa (Cypress), and Cryptomeria japonica (Cedar) in temperate forests of Japan. Bacterial and fungal communities were assessed using MiSeq high-throughput sequencing system, while nematodes were morphologically identified at the genus/family level and examined for both community structure and trophic composition. Our results showed that fungal and nematode abundances were significantly or marginally higher in pine soils, respectively. There were no significant differences in the abundance of bacteria among the four tree species. Fungal richness was significantly higher in cypress stands, while nematode richness was greater in cedar stands. Fungal richness was strongly influenced by root traits, whereas nematode richness was primarily explained by soil properties. There were no significant differences in the richness of bacteria among four tree species. Community structures of bacterial, fungal, and nematode varied significantly among the four tree species. Moreover, soil properties significantly influenced the community structures of all three-soil biota, whereas root-traits did not influence the community structures. These findings suggest that unique soil biological communities are shaped by the soil environment those root systems modify.journal articl
