Cuticular wax covers surfaces of land plants and serves as a protective barrier against water loss, UV-light, pathogens and insects. Major wax components are derived from saturated very long chain fatty acids (> C26 in length) via two wax biosynthetic pathways: an acyl reduction pathway and a decarbonylation pathway. Similar compositions of wax constituents comprising cuticular wax of Arabidopsis and other plant species suggest that these pathways are highly conserved in the plant kingdom. However, our knowledge of the wax biosynthetic enzymes, the nature of the biochemical reactions that they catalyze and their localization within the cell is limited.

表皮蜡覆盖在陆地植物的表面，作为防止水分流失、紫外线、病原体和昆虫的保护屏障。主要的蜡组分通过两种蜡生物合成途径从饱和的极长链脂肪酸（长度> C26）衍生：酰基还原途径和脱羰基途径。拟南芥和其他植物物种的表皮蜡组成的蜡成分的相似组合物表明，这些途径在植物界是高度保守的。然而，我们对蜡生物合成酶、它们催化的生化反应的性质及其在细胞内的定位的了解有限。
