Functional Endophytes Regulating Plant Secondary Metabolism: Current Status, Prospects and Applications

Abstract

Endophytes, which are widely found in host plants and have no harmful effects, are a vital biological resource. Plant endophytes promote plant growth and enhance plants’ resistance to diseases, pests, and environmental stresses. In addition, they enhance the synthesis of important secondary metabolites in plants and improve the potential applicability of plants in agriculture, medicine, food, and horticulture. In this review, we summarize the recent progress in understanding the interaction between endophytes and plants and summarize the construction of synthetic microbial communities (SynComs) and metaomics analysis of the interaction between endophytes and plants. The application and development prospects of endophytes in agriculture, medicine, and other industries are also discussed to provide a reference for further study of the interaction between endophytes and plants and further development and utilization of endophytes.

Enriching the endophytic bacterial microbiota of Ginkgo roots

“…On the one hand, the collected microorganisms can be used to elucidate their ecological roles and biosynthesize their own secondary metabolites. On the other hand, these microorganisms can be selected and constructed a community, which is useful to explore the plant–microbe interaction and promote the biosynthesis of plant's secondary metabolites (Carper et al, 2021 ; Li et al, 2023 ). Thus, the future of endophytic microbes is as bright as their demand for their utilization in agriculture and medicine as well as in industry, which will enlarge day by day.…”

Antibacterial Mechanism, Control Efficiency, and Nontarget Toxicity Evaluation of Actinomycin X2 against Xanthomonas citri Subsp. citri

“…However, the most attractive topic is always the discovery of new antibacterial ingredients, particularly those extracted from natural products. Plant endophytes inhabit the plant to assist in its growth by metabolizing bioactive compounds that might protect the host from infection by other pests, which are essential for the healthy growth of some plants . Therefore, plant endophytes are a great resource for the production of pharmaceuticals or pesticides.…”
