Trait-based approaches have been increasingly used to relate plants to soil microbial communities. Using the recently described root economics space as an approach to explain the structure of soil-borne fungal communities, our study in a grassland diversity experiment reveals distinct root trait strategies at the plant community level. In addition to significant effects of plant species richness, we show that the collaboration and conservation gradient are strong drivers of the composition of the different guilds of soil fungi. Saprotrophic fungi are most diverse in species-rich plant communities with 'slow' root traits, whereas plant pathogenic fungi are most diverse and abundant in communities with 'fast' and 'DIY' root traits. Fungal biomass is strongly driven by plant species richness. Our results illustrate that the root economics space and plant species richness jointly determine the effects of plants on soil fungal communities and their potential role in plant fitness and ecosystem functioning.
基于性状的方法越来越多地被用于将植物与土壤微生物群落联系起来。利用最近描述的根系经济空间作为解释土壤传播真菌群落结构的一种方法，我们在草地多样性实验中的研究揭示了植物群落水平上不同的根系性状策略。除了植物物种丰富度的显著影响外，我们还表明协作和保守梯度是不同土壤真菌类群组成的强大驱动因素。腐生真菌在具有“慢”根系性状的物种丰富的植物群落中种类最多，而植物病原真菌在具有“快”和“自主型”根系性状的群落中种类最多且数量丰富。真菌生物量受植物物种丰富度的强烈驱动。我们的结果表明，根系经济空间和植物物种丰富度共同决定了植物对土壤真菌群落的影响及其在植物适应性和生态系统功能中的潜在作用。
