Abstract

Bacterial leaf blight (BLB) in rice, caused by the pathogen Xanthomonas oryzae pv. oryzae, is a significant agricultural problem managed through chemical control and cultivating rice varieties with inherent resistance to the bacterial pathogen. Research has highlighted the potential of using antagonistic microbes which can suppress the BLB pathogen through the production of secondary metabolites like siderophores, rhamnolipids, and hydroxy-alkylquinolines offering a sustainable alternative for BLB management. Additionally, the induction of plant immunity and defense-related enzymes in rice further enhances the resistance against the disease. Therefore, implementation of biological controls can complement chemical treatments in contributing towards the sustainability of rice production systems by aiming at host immunity improvement and killing of pathogen. It is crucial to continue exploring and understanding the complex interactions between various beneficial microbes, the rice plants, and the BLB pathogen to optimize and implement effective biocontrol strategies in future.

水稻白叶枯病的生物防治——可持续对策

水稻细菌性叶枯病（BLB），由水稻黄单胞菌引起。稻瘟病是一个重要的农业问题，通过化学防治和培育具有内在抗性的水稻品种来管理。研究强调了利用拮抗微生物的潜力，拮抗微生物可以通过产生次生代谢物如铁载体、鼠李糖脂和羟基烷基喹啉来抑制BLB病原体，为BLB管理提供了可持续的替代方案。此外，植物免疫和防御相关酶在水稻中的诱导作用进一步增强了水稻对病害的抗性。因此，实施生物防治可以补充化学处理，通过提高宿主免疫力和杀死病原体，促进水稻生产系统的可持续性。因此，继续探索和了解各种有益微生物、水稻植株和BLB病原菌之间复杂的相互作用对于优化和实施有效的生物防治策略至关重要。
