植物表皮蜡质生物合成及调控

Research Progress in Plant Cuticular Wax Biosynthesize and Regulation

植物表皮蜡质,是覆盖在陆地植物地上部分表面的一层疏水性脂类物质,是植物应对外界环境变化的第一道屏障,在抑制植物水分非气孔散失及保护植物免受病虫害入侵、紫外线辐射等方面起着重要作用。综述了近年来表皮蜡质在生物合成及调控等方面的研究进展,并对研究中存在的问题及研究前景进行了展望。

The epicuticular wax coating the aerial surface of land plants is a hydrophobic lipid component,which forms a barrier against environmental stresses. It plays key roles in restricting non-stomatal water loss,protecting plants against the attack of pathogen and insect,and ultraviolet radiation. Recent progress on the biosynthesis pathway and regulation of epicuticular wax was reviewed. The questions and future application were discussed.
