A layer of cuticular wax is deposited on the surface of terrestrial plants, which reduces the damage caused by environmental stress and maintains growth in a relatively stable internal environment. Apple cuticular wax is an important part of the fruit epidermis that plays an essential role in apple development, storage, and adaptation to environmental stress. The formation of cuticular wax has been described at the transcriptional, post-transcriptional, and translational levels in Arabidopsis, whereas less research has been performed on apple cuticular wax. Here, we provide a brief overview of how apple cuticular wax is formed, as well as its structure, composition, and function. An association among the environment, genes, and apple cuticular wax deposition was revealed. Cuticular wax prevents fruit rust from occurring on apple. Taken together, a detailed understanding of apple cuticular wax is discussed. The results will act as a reference for extending the storage period and increasing the commodity value of apple.
一层角质蜡沉积在陆生植物的表面，这减少了环境胁迫造成的损害，并使植物在相对稳定的内部环境中维持生长。苹果角质蜡是果实表皮的重要组成部分，在苹果的发育、储存以及对环境胁迫的适应中发挥着至关重要的作用。在拟南芥中，已经在转录、转录后和翻译水平上描述了角质蜡的形成，而关于苹果角质蜡的研究较少。在此，我们简要概述了苹果角质蜡的形成方式及其结构、组成和功能。揭示了环境、基因与苹果角质蜡沉积之间的关联。角质蜡可防止苹果果实发生锈病。综上所述，本文讨论了对苹果角质蜡的详细理解。这些结果将为延长苹果储存期和提高苹果商品价值提供参考。
