摘要：Background and aimsMycorrhizal fungi play crucial roles in shaping plant functional traits and adaptation strategies. However, the relationships between soil fungal diversity and plant functional traits in bamboo forests remain insufficiently explored. Given bamboo's unique clonal growth habit, bamboo ecosystems offer an intriguing model to investigate mycorrhizal-plant interactions across elevational gradients, where environmental conditions change continuously.MethodsA field study was conducted in bamboo forests dominated by Pleioblastus amarus. Across four elevations, we measured (1) plant-related traits (endogenous hormones, non-structural carbon (NSC) content, shoot density, and shoot biomass) and (2) soil properties (physicochemical characteristics, fungal community composition and soil fungal diversity).ResultsFirst, although the alpha diversity of soil fungi did not differ among the four bamboo forests, soil fungal diversity was significantly correlated with rhizome phytohormones, with taxonomic-level variations in the strength and direction of these correlations with plant traits. Second, shoot density and shoot biomass showed opposing trends, reflecting functional trade-offs, while endogenous hormones and NSC content exhibited significant changes across the four bamboo forests. Third, key soil physicochemical properties, including soil pH, SM, and total phosphorus, also differed significantly among these bamboo forests.ConclusionsThe taxon-specific correlations between fungi and plant traits suggest that specialized fungal symbionts promote plant hormonal adjustments, thereby supporting P. amarus' adaptive strategies under changing environmental conditions along elevational gradients.
