植物角质层内外蜡质的差异及其与抗逆性的关系

植物角质层是覆盖在植物地上部分的叶、花和非木质茎等器官表面的保护层，包括角质和蜡质。其中蜡质根据分布位置不同又分为表皮蜡质和内部蜡质。大量研究表明，表皮蜡质含量和结构在植物生长发育和抗逆性申发挥着重要作用。近年来有研究发现构成蜡质的成分在内外蜡质层中的分布存在差异，角质层蜡质成分影响植物抗逆性。本文针对角质层结构和内外蜡质差异性以及角质层结构和组成与植物抗逆性之间的关系进行了综述。

Composition Differences of Epicuticular and Intracuticular Wax Layers and the Relationship between Cuticle and Plant Stress Tolerance

Plant cuticle serves as a protective layer and consists of cutin and waxes,which is covered on the outmost surfaces of plant leaves,flowers and non-woody stems organs.Furthermore,an epicuticular layer and an intracuticular layer can be distinguished according to the wax location within the cutin matrix,respectively.Many reports have proved that epicuticular wax loads and intact structure play important roles in plant growth,development and in response to stresses.Recently,wax compositional differences betwe...
