微生物凭借其丰富的物种多样性和重要的生态系统功能（例如生物地球化学循环和菌根共生）在陆地生态系统中占据主导地位。真菌和其他生物体形成不同的关联网络。然而，属于不同王国的物种在多王国社区网络中的作用仍然很大程度上难以捉摸。根据综合微生物组倡议，我们使用 SPIEC-EASI 方法从高海拔林线土壤中推断出多界生物关联。在群落和网络层面调查了植物、线虫、真菌、细菌和古细菌之间的生物相互作用。与单王国网络相比，多王国网络及其关联使王国内和跨王国的边数分别增加了 1012 和 10,772，平均连通性和负边比例分别增加了 15.2% 和 0.8%。与植物、线虫、细菌和古细菌的单界网络相比，真菌的参与增加了网络稳定性（即对节点丢失的抵抗力）和连接性，但降低了模块化程度。在整个多界网络中，真菌节点的特征是显着高于细菌的度数和介数。真菌更多时候扮演连接器的角色，连接不同的模块。一致地，结构方程模型和矩阵多元回归证实了真菌在群落水平上连接植物和其他土壤生物群的“桥梁”作用。总的来说，我们的研究结果表明真菌可以稳定多界网络的自组织过程。这些发现促进了自然生态系统中多界群落研究的启动和开展，以揭示复杂的地上和地下联系。
Microbes dominate terrestrial ecosystems via their great species diversity and vital ecosystem functions, such as biogeochemical cycling and mycorrhizal symbiosis. Fungi and other organisms form diverse association networks. However, the roles of species belonging to different kingdoms in multi‐kingdom community networks have remained largely elusive. In light of the integrative microbiome initiative, we inferred multiple‐kingdom biotic associations from high elevation timberline soils using the SPIEC‐EASI method. Biotic interactions among plants, nematodes, fungi, bacteria, and archaea were surveyed at the community and network levels. Compared to single‐kingdom networks, multi‐kingdom networks and their associations increased the within‐kingdom and cross‐kingdom edge numbers by 1012 and 10,772, respectively, as well as mean connectivity and negative edge proportion by 15.2 and 0.8%, respectively. Fungal involvement increased network stability (i.e., resistance to node loss) and connectivity, but reduced modularity, when compared with those in the single‐kingdom networks of plants, nematodes, bacteria, and archaea. In the entire multi‐kingdom network, fungal nodes were characterized by significantly higher degree and betweenness than bacteria. Fungi more often played the role of connector, linking different modules. Consistently, structural equation modeling and multiple regression on matrices corroborated the “bridge” role of fungi at the community level, linking plants and other soil biota. Overall, our findings suggest that fungi can stabilize the self‐organization process of multi‐kingdom networks. The findings facilitate the initiation and carrying out of multi‐kingdom community studies in natural ecosystems to reveal the complex above‐ and belowground linkages.
