超长链脂肪酸（即，具有超过18个碳原子的脂肪酸（VLCFA）是在植物中发挥关键生理和结构作用的重要分子。VLCFA特异性地存在于几种膜脂质中，并且对于膜稳态是必需的。它们在质膜外叶鞘脂中的特异性积累对于其在细胞间通讯中的正确功能至关重要。VLCFA存在于磷脂中，特别是磷脂酰丝氨酸和磷脂酰乙醇胺中，它们可能在膜结构域组织和小叶间偶联中发挥作用。在表皮细胞中，VLCFA是植物角质层的角质蜡的前体，其对于植物与其周围环境的许多相互作用至关重要。VLCFA也是根木栓质屏障的主要组分，其已被证明是营养平衡和植物适应不利条件的基础。最后，一些植物将VLCFA储存在其种子的三酰甘油中，以便它们以后在种子萌发中发挥关键作用。在这篇综述中，利用拟南芥作为模型进行的许多研究，我们目前的知识VLCFA在植物中的生物合成和调节，以及VLCFA及其衍生物在植物与其非生物和生物环境的相互作用中发挥的各种功能。
Very-long-chain fatty acids (i.e., fatty acids with more than 18 carbon atoms; VLCFA) are important molecules that play crucial physiological and structural roles in plants. VLCFA are specifically present in several membrane lipids and essential for membrane homeostasis. Their specific accumulation in the sphingolipids of the plasma membrane outer leaflet is of primordial importance for its correct functioning in intercellular communication. VLCFA are found in phospholipids, notably in phosphatidylserine and phosphatidylethanolamine, where they could play a role in membrane domain organization and interleaflet coupling. In epidermal cells, VLCFA are precursors of the cuticular waxes of the plant cuticle, which are of primary importance for many interactions of the plant with its surrounding environment. VLCFA are also major components of the root suberin barrier, which has been shown to be fundamental for nutrient homeostasis and plant adaptation to adverse conditions. Finally, some plants store VLCFA in the triacylglycerols of their seeds so that they later play a pivotal role in seed germination. In this review, taking advantage of the many studies conducted using Arabidopsis thaliana as a model, we present our current knowledge on the biosynthesis and regulation of VLCFA in plants, and on the various functions that VLCFA and their derivatives play in the interactions of plants with their abiotic and biotic environment.
