摘　　要：角质层,包括角质和蜡质,是主要由脂肪酸及其衍生物构成的覆盖在植物的外表面的高度疏水层,在植物生长发育过程中起到非常重要的保护屏障作用。除了在极端温度、干旱、高盐等多种非生物逆境胁迫下起到保护作用外,还能够保护植物内部组织免受细菌、真菌病原体的侵染。现就植物角质层的组成、合成途径以及与植物抗逆性,特别是与抗旱能力的关系方面的最新研究进展进行了综述。Plant cuticle plays an important role in the plant life cycle. The cuticle is highly hydrophobic layer of cutin intermeshed and coated with waxes that covers essentially all aerial organs and mainly composed of fatty acids and their derivatives. Plant cuticle can be divided into the inner cutin and outer wax layer and forms a protective layer against temperature extremes, drought, high salinity and other abiotic stresses. The cuticle also protects inner tissues from bacterial and fungal the relationship between plant cuticle and stress pathogens, herbivore attacks. The recent research progresses in resistance, especially drought tolerance were reviewed.
