地上和地下生物群落之间的相互作用驱动植物和土壤微生物群的群落组装。根际真菌作为地下微生物的重要组成部分，在宿主植物的生物多样性维持和群落组装中发挥着重要作用。桦木科植物与土壤真菌形成外生菌根，广泛分布于各种生态系统中。然而，在大的空间尺度上，外生菌根内生真菌的群落组装研究较少。利用Illumina Miseq测序技术，对中国森林生态系统中桦木科4属22种外生菌根真菌的内生真菌群落进行了研究。揭示了寄主植物的发生、气候和土壤（环境过滤）以及地理距离（扩散限制）对内生真菌群落的相对贡献。在97%的序列相似性水平上，共获得了2,106个内生真菌操作分类单位（OTU），以Leotiomycetes、Agaricomycetes、Eurotiomycetes和Sordariomycetes为主。植物内生真菌OTU丰度与寄主植物的地理距离、土壤和气候等因素有显著相关。内生真菌群落组成受寄主植物发生（19.5%的变异由真菌群落解释）、地理距离（11.2%）、土壤（6.1%）和气候（1.4%）的显著影响。这一发现表明，环境过滤植物和非生物变量加上地理距离的传播限制决定了内生真菌群落组装桦木科植物的外生菌根，宿主的共生性是一个更强的决定因素比其他预测变量在区域尺度上。
The interaction between aboveground and belowground biotic communities drives community assembly of plants and soil microbiota. As an important component of belowground microorganisms, root-associated fungi play pivotal roles in biodiversity maintenance and community assembly of host plants. The Betulaceae plants form ectomycorrhizae with soil fungi and widely distribute in various ecosystems. However, the community assembly of endophytic fungi in ectomycorrhizae is less investigated at a large spatial scale. Here, we examined the endophytic fungal communities in ectomycorrhizae of 22 species in four genera belonging to Betulaceae in Chinese forest ecosystems, using Illumina Miseq sequencing of internal transcribed spacer 2 amplicons. The relative contribution of host phylogeny, climate and soil (environmental filtering) and geographic distance (dispersal limitation) on endophytic fungal community was disentangled. In total, 2,106 endophytic fungal operational taxonomic units (OTUs) were obtained at a 97% sequence similarity level, dominated by Leotiomycetes, Agaricomycetes, Eurotiomycetes, and Sordariomycetes. The endophytic fungal OTU richness was significantly related with host phylogeny, geographic distance, soil and climate. The endophytic fungal community composition was significantly affected by host phylogeny (19.5% of variation explained in fungal community), geographic distance (11.2%), soil (6.1%), and climate (1.4%). This finding suggests that environmental filtering by plant and abiotic variables coupled with dispersal limitation linked to geographic distance determines endophytic fungal community assembly in ectomycorrhizae of Betulaceae plants, with host phylogeny being a stronger determinant than other predictor variables at the regional scale.
