| 摘 要： | 角质蜡质是植物在长期的生态适应过程中进化形成的一类次生代谢产物，广泛参与了植物抗逆、抵御病虫害侵染等诸多抗性生理过程。角质蜡质在植物-病原互作中发挥了重要作用，是植物抗病机制的重要组成部分。随着分子生物学的发展，人们对植物角质蜡质代谢及其抗病机理的认知不断深入。本研究综述了植物角质蜡质生物合成与其抗病机理的最新研究进展并对未来研究提出展望。目前，植物角质蜡质的抗性机理研究主要集中于组成型抗性和诱导型抗性2类。角质蜡质作为角质层主要成分，一方面可作为组成型抗性成分发挥物理抗性(物理屏障)和化学抗性(抑菌)作用；另一方面，也可作为诱导型抗性成分发挥作用，诱导产生的角质蜡质单体除了作为角质层主要成分发挥物理抗性外，也可作为信号分子或者诱导子激活下游的抗性反应进而发挥其化学抗性功能。未来可侧重于对角质蜡质诱导抗性机理的深入阐释，进一步丰富植物化学生态学研究理论体系。此外，基于角质蜡质的诱导抗性作用，可开发角质蜡质类生物农药(植物免疫诱导剂)，为植物病害防控提供新思路。图1参71

| Abstract: | As a type of secondary metabolites produced by plants during long-term ecological adaptation, cutin and wax are widely involved in many resistance physiological processes including stress defense and resistance to pests and diseases, playing critical roles in the plant-pathogen interaction, thus becoming an important part of plant disease resistance mechanism. With the development of molecular biology, there is an increasing understanding on the cutin and wax metabolism and their mechanisms against fungal disease in plant. With prior researches mainly focused on the constitutive resistance and inducible resistance of plant cutin and wax, the present study, with a review of the research progress achieved on the plant cutin and wax biosynthesis and its disease resistance mechanism, is aimed to put forward prospects for future research. It was concluded that (1) as the main components of the cuticle, the first line of defense for plants against pathogen infection, cutin and wax play a critical role in physical resistance (physical barrier) and chemical resistance (bacteriostasis) as constitutive resistance components, (2) They can also play the role of inducible resistance components and (3) in addition to being the main component of the cuticle to exert physical resistance, the inducible cutin and wax component can also act as a signal molecule or inducer to activate downstream resistance reactions and exert its chemical resistance function. In the future, the research concerning cutin and wax can be focused on an in-depth explanation of the mechanism of cutin and wax inducible resistance, so as to further enrich the theoretical system of plant chemical ecology. In addition, cutin and wax biopesticides (plant immunity inducers) can be developed based on the inducible resistance of cutin and wax to provide new insight for the plant diseases control.
