One of the latest ecological concepts is the occurrence of a biased rhizosphere of microorganisms recruited mostly through interactions among various components of the rhizosphere, including plant roots and the bulk soil microbiome. We compared the diverse attributes of the core microbiome of wheat rhizosphere communities with wheat (W) and legume (L) forecrops determined by three different methods in this study (membership, composition, and functionality). The conclusions of the three methods of microbiome core definition suggest the presence of generalists, i.e., some representative microorganisms from Proteobacteria, Actinobacteria, Hypomicrobiaceae, Bradyrhizobiaceae, sp., in the wheat rhizomicrobiome. The relative abundance of the core microbiome accounted for 0.1976% (W) and 0.334% (L)-membership method and 6.425% (W) and 4.253% (L)-composition method. Additionally, bacteria of the specialist group, such as sp., are functionally important in the rhizomicrobiome core. This small community is strongly connected with other microbes and is essential for maintenance of the sustainability of certain metabolic pathways.
最新的生态学概念之一是存在一个有偏向性的根际微生物群落，其主要通过根际各组成部分（包括植物根系和土壤微生物群落）之间的相互作用招募而来。在本研究中，我们用三种不同方法（成员身份、组成和功能）比较了小麦根际群落核心微生物组在小麦（W）和豆科（L）前作情况下的不同属性。三种微生物组核心定义方法的结论表明存在一些通用型微生物，即在小麦根际微生物组中来自变形菌门、放线菌门、亚硝化单胞菌科、慢生根瘤菌科等的一些代表性微生物。核心微生物组的相对丰度在成员身份法中占0.1976%（W）和0.334%（L），在组成法中占6.425%（W）和4.253%（L）。此外，特定种类的专性微生物在根际微生物组核心中具有重要功能。这个小群落与其他微生物紧密相连，对维持某些代谢途径的可持续性至关重要。
