Root-associated fungi (RAF) link nutrient fluxes between soil and roots and thus play important roles in ecosystem functioning. To enhance our understanding of the factors that control RAF, we fitted statistical models to explain variation in RAF community structure using data from 150 temperate forest sites covering a broad range of environmental conditions and chemical root traits. We found that variation in RAF communities was related to both root traits (e.g., cations, carbohydrates, NO ) and soil properties (pH, cations, moisture, C/N). The identified drivers were the combined result of distinct response patterns of fungal taxa (determined at the rank of orders) to biotic and abiotic factors. Our results support that RAF community variation is related to evolutionary adaptedness of fungal lineages and consequently, drivers of RAF communities are context-dependent.
根相关真菌（RAF）连接着土壤和根系之间的养分流动，因此在生态系统功能中发挥着重要作用。为了增强我们对控制 RAF 的因素的理解，我们使用了来自 150 个温带森林站点的数据，这些站点涵盖了广泛的环境条件和化学根特性，通过统计模型来解释 RAF 群落结构的变化。我们发现，RAF 群落的变化与根特性（例如阳离子、碳水化合物、NO ）和土壤特性（pH 值、阳离子、水分、C/N）有关。确定的驱动因素是真菌分类群（在目等级上确定）对生物和非生物因素的不同反应模式的综合结果。我们的研究结果支持 RAF 群落的变化与真菌谱系的进化适应性有关，因此 RAF 群落的驱动因素是依赖于上下文的。
