Root‐associated microbiomes play significant roles in plant productivity, health and ecological services. However, our current understanding of the microbial assemblages in the rhizosphere and endosphere of herbage is still limited. To gain insights into these microbial assemblages, Illumina MiSeq high‐throughput sequencing was performed to investigate the characteristics of microbial communities of an herbage, Leymus chinensis. Hierarchical clustering analysis and principal coordinate analysis (PCoA) results showed that microbial communities of the rhizosphere and endosphere samples were clearly distinguished. Rhizosphere soil communities showed a greater sensitivity than root endosphere communities using linear discriminant analysis (LDA) effect size (LEfSe). Rhizosphere and endosphere communities performed their respective functions in the soil as a cohesive collective, and Rhizobiales were observed to function as generalists. Redundancy analysis (RDA) and variance partitioning analysis (VPA) results revealed that the contribution of the interaction between soil physicochemical parameters and soil enzymes was greater than their individual contributions. In summary, this study is the first to elucidate the microbial diversity and community structure of L. chinensis and compare the diversity and composition between rhizospheric and endosphere microbiomes.

与草本植物羊草的根际和内圈相关的微生物群落。
根相关微生物组在植物生产力、健康和生态服务中发挥着重要作用。然而，我们目前对草本植物根际和内圈微生物组合的了解仍然有限。为了深入了解这些微生物组合，我们进行了 Illumina MiSeq 高通量测序来研究草本植物羊草(Leymus chinensis)的微生物群落特征。层次聚类分析和主坐标分析（PCoA）结果表明根际和内圈样品的微生物群落明显区分。使用线性判别分析（LDA）效应大小（LEfSe），根际土壤群落表现出比根内圈群落更高的敏感性。根际和内圈群落作为一个有凝聚力的集体在土壤中发挥各自的功能，并且根瘤菌被观察到具有通才的功能。冗余分析（RDA）和方差分配分析（VPA）结果表明，土壤理化参数和土壤酶之间相互作用的贡献大于它们各自的贡献。综上所述，本研究首次阐明了羊草的微生物多样性和群落结构，并比较了根际和内圈微生物组的多样性和组成。
