细菌铁载体拮抗植物病原真菌及促生作用研究进展

铁载体是微生物在缺铁条件下分泌的小分子有机化合物，以获取铁元素维持其生长。细菌分泌的铁载体在拮抗植物病原菌和促进植物生长方面具有重要作用。本文总结了细菌铁载体拮抗植物病原真菌的营养和生态位竞争、诱导植物诱导性系统抗性、扰乱病原菌铁稳态的机制，以及促进植物生长的作用，以解释细菌分泌的铁载体在多功能微生物菌剂研制中的重要作用。

Bacterial siderophores antagonize phytopathogenic fungi and promote plant growth:a review

Siderophores are small organic molecules produced by microorganisms under iron-limiting conditions which enhance the uptake of iron to microorganisms. Bacterial siderophores play an important role in antagonizing plant pathogens and promoting plant growth. In this paper, we summarized the mechanisms of bacterial siderophores against plant pathogenic fungi, such as nutrient competition, niche competition, eliciting inducible systemic resistance in plants, and disrupting the iron homeostasis of pathogens, and the plant growth-promoting effect of the siderophores, aiming at clarifying the potential of bacterial siderophores in the development of multifunctional microbial agents.
