Recently, the Tobacco Research Institute of the Chinese Academy of Agricultural Sciences has made important progress in new strategies for the biological control of crop soil-borne diseases. Frontiers of Science (Frontiers in Plant Science)” (JCR top 25%).
Soil-borne diseases seriously endanger agricultural production, and their prevention and control are still a worldwide problem. For a long time, scientists around the world have been committed to clarifying the relationship between plant-related microorganisms on host growth and disease resistance, and applying research results to agricultural production. However, due to the neglect of examining and discovering the relationship between microbial structure and function at the community level, the effect of the existing microbial strains in the field is generally poor, which is characterized by unstable, unsatisfactory, and weak rhizosphere colonization ability.
In fact, the rhizosphere microorganisms may really play a role in a few key microbial groups, the core microbiome. Therefore, finding the soil core microbiome is expected to alleviate the problems of the ecological environment, agricultural production and current microbial preparations. Recently, researchers from the Tobacco Institute comprehensively analyzed the microbial community structure and function of tobacco bacterial wilt disease-suppressing soil, using the co-occurrence network to identify the key microbial groups in the disease-suppressing soil, and obtaining key strains by means of microbial isolation and cultivation. The fungus can effectively reduce the infection of tobacco by Ralstonia solanacearum. This research created a research paradigm for the design and synthesis of new biocontrol agents based on the core microbiome of the plant rhizosphere, and provided a new strategy for the development of a new generation of biocontrol agents with more targeted, higher efficiency and better effects.
