    Potential and application of plant volatile organic compounds in agricultural disease control

    • 摘要: 植物病害对全球粮食安全造成严重威胁,而病原物对杀菌剂日益严重的抗药性问题和杀菌剂施用导致的环境暴露风险极大限制了传统杀菌剂的开发。植物释放大量挥发性有机化合物 (volatile organic compounds, VOCs) 到大气中作为植物与周围环境交流互动的信号分子。植物VOCs可以保护自身免受食草动物的侵害,或吸引传粉者和种子传播者,它们还能够直接抑制病原菌的生长或者激活植物的防御系统。本文综述了植物VOCs在生物合成、收集分析、诱导释放、对病原微生物的活性和诱导植物免疫反应等方面的研究进展;总结了典型绿叶挥发物反-2-己烯醛的抑菌和抗性诱导机理;归纳和展望了植物VOCs在田间应用的局限性和今后的研究方向,可为该类化合物在可持续病害防控中的应用提供帮助。

       

      Abstract: Plant diseases caused by phytopathogenic microorganisms seriously threaten the global food security, and the development of traditional fungicides is greatly limited by the increasing resistance of pathogens to fungicides and the environmental exposure risks caused by fungicide application. A large number of plant volatile organic compounds (VOCs) are released back into the atmosphere as signal molecules for communication and interaction between plants and the surrounding environment. Plant VOCs can protect themselves from herbivores, or attract pollinators and seed dispersers. They can also directly inhibit the growth of pathogens or activate plant defense systems. This paper reviewed the research progresses in the biosynthesis, collection, analysis, and induced release of plant VOCs, their bioactivity against phytopathogenic microorganisms, and induction of plant immune response; summarized the molecular mechanisms of the antibacterial activity and induced disease resistance of typical green leaf volatile trans-2-hexenal; discussed the limitations of plant VOCs in field applications and the prospects of future research, laying a foundation for the application of such compounds in sustainable disease control.
