Drought, salinity, extreme temperatures, and ultraviolet (UV) radiation are major environmental factors that adversely affect plant growth and crop production. As a protective shield covering the outer epidermal cell wall of plant aerial organs, the cuticle is mainly composed of cutin matrix impregnated and sealed with cuticular waxes, and greatly contributes to the plant adaption to environmental stresses. Past decades have seen considerable progress in uncovering the molecular mechanism of plant cutin and cuticular wax biosynthesis, as well as their important roles in plant stress adaptation, which provides a new direction to drive strategies for stress-resilient crop breeding. In this review, we highlighted the recent advances in cuticle biosynthesis in plant adaptation to drought, salinity, extreme temperatures, and UV radiation stress, and discussed the current status and future directions in harnessing cuticle biosynthesis for crop improvement.
干旱、盐碱、极端温度和紫外线（UV）辐射是对植物生长和作物产量产生不利影响的主要环境因素。作为覆盖植物地上器官外表皮细胞壁的保护屏障，角质层主要由浸渍有角质蜡并被其密封的角质基质组成，在植物适应环境胁迫方面发挥着重要作用。在过去几十年中，在揭示植物角质和角质蜡生物合成的分子机制及其在植物胁迫适应中的重要作用方面取得了相当大的进展，这为推动抗逆作物育种策略提供了新方向。在本综述中，我们重点介绍了植物在适应干旱、盐碱、极端温度和紫外线辐射胁迫过程中角质层生物合成的最新进展，并讨论了利用角质层生物合成改良作物的现状和未来方向。
