陆地植物的气生部分覆盖有角质层蜡，其限制非气孔水分损失和气体交换，并保护植物免受紫外线辐射和病原体攻击。它们由极长链脂肪酸（VLCFA; C20至C34）以及它们的衍生物、醛、烷烃、伯醇和仲醇和蜡酯组成。由于其物理性质，如室温下的固体和从透明到不透明的半透明性，植物蜡已被用作化妆品、洗涤剂、塑料、肥皂、油漆、药物、润滑剂和高价值可再生燃料生产的原材料。许多参与表皮蜡生物合成和输出的基因已经通过正向和反向遗传学方法以及茎表皮转录组分析进行了表征。表皮蜡生物合成的调控机制已在转录、转录后和翻译水平上报道。本文综述了近年来植物表皮蜡生物合成及其调控的研究进展。
The aerial parts of land plants are covered with cuticular waxes that limit non-stomatal water loss and gaseous exchanges, and protect plants from ultraviolet radiation and pathogen attacks. They are composed of very-long-chain fatty acids (VLCFAs; C20 to C34) in addition to their derivatives, aldehydes, alkanes, primary and secondary alcohols, and wax esters. Due to their physical properties, such as solidity at room temperature and a translucency ranging from transparent to opaque, plant waxes have been used as raw materials in the production of cosmetics, detergents, plastics, soaps, paints, drugs, lubricants, and high-value renewable fuels. Many genes involved in cuticular wax biosynthesis and export have been characterized by forward and reverse genetic approaches as well as by stem epidermis transcriptome analysis. The regulatory mechanisms of cuticular wax biosynthesis have been reported at the transcriptional, posttranscriptional, and translational levels. Recent advances in cuticular wax biosynthesis and its regulation are reviewed in this paper.
