病原菌胁迫下植物“呼救”策略的研究进展

Research progress in the “cry for help” strategy of plants under pathogen stress

摘要:

植物在生长过程中会受到生物与非生物性胁迫，其中病原菌侵染是生物胁迫中的重要组成部分。由于植物微生物组与植物共同生长进化，当植物受到病原菌胁迫时会通过特殊分泌物或招募有益菌对抗病原菌。本文从病原菌胁迫下植物微生物组变化、植物代谢产物变化、植物-微生物互作机制和植物“呼救”后形成的抑病土壤等方面阐述植物“呼救”策略研究进展，为植物土传病害防控提供参考依据。

Abstract:

Plants are subjected to biotic and abiotic stresses during growth, of which pathogen infection is a major biotic stress. Since the plant microbiome co-evolves with plants, the plants exposed to pathogen stress will fight against pathogens by special secretions or recruitment of beneficial microorganisms. This paper reviews the research progress in the “cry for help” strategy of plants under pathogen stress from the changes in plant microbiome and metabolites, plant-microbe interactions, the disease-suppressive soil formed after the plant “cry for help”, with a view to providing a basis for the prevention and control of soil-borne diseases in plants.
