The relationship between the root-inter-bacteria, bacteria and fungal communities of wheat in the North China Plain was studied.

The root contains a wealth of microbiome, the competition between the root micro-organisms, cooperative relations jointly promote the stability of the inter-root microenvironment and nutrient circulation process, to the growth and health of crops play an important role. The study of the inter-root microbial relationship of
is mainly limited to the control experiment, and the study of the intergenic bacteria, bacteria and fungal communities and their influencing factors are lacking in large spatial scale.
based on this, the Research Group of the Nanjing Soil Research Institute of the Chinese Academy of Sciences used co-occurrence network analysis (co-occurrence network) to study the interrelationship between wheat root bacteria, bacteria and fungal communities in the North China Plains on a large scale, focusing on exploring the complexity and stability of the inter-root microbial network, and excavating the root core microbiome (Keystone) microbiome.
studies have found that the structure of the inter-root microbial network is relatively simple but more stable compared with non-root soil microbes, the soil pH and microbiodiversity have positive feedback on the size and connectivity of the network, the core flora of the network has relatively flexible metabolic characteristics, and the core flora in the root is less disturbed by environmental factors.
this study clarifies the relatively simple but more stable microbial community in the inter-root microenvironment, analyzes the biological and non-biological factors that affect the characteristics of microbial networks, and excavates the core microbial microbiome and its perturbation factors from the perspective of the stability of the network structure, which provides a scientific basis for the reconstruction of stable agricultural microbial communities in the future.
