Oxylipins comprise a group of biologically active compounds whose structural diversity is generated by the coordinate action of lipases, lipoxygenases, and a group of cytochromes P450 that are specialized for the metabolism of hydroperoxy fatty acids. Research on oxylipins has focused mainly on the biosynthesis of the plant signaling molecule jasmonic acid, and its role in the regulation of developmental and defense-related processes. Recent genetic studies indicate that metabolic precursors of jasmonate are active as signals in their own right, and that the synthesis and perception of jasmonates is critical for wound-induced systemic defense responses. Increasing evidence indicates that the collective biological importance of oxylipins in plants is comparable to that of the eicosanoid family of lipid mediators in animals.
氧脂素是一类生物活性化合物，其结构多样性是由脂肪酶、脂氧合酶以及一组专门用于氢过氧脂肪酸代谢的细胞色素P450共同作用产生的。对氧脂素的研究主要集中在植物信号分子茉莉酸的生物合成及其在发育和防御相关过程调控中的作用。最近的遗传学研究表明，茉莉酸的代谢前体本身就具有信号活性，而且茉莉酸的合成和感知对于伤口诱导的系统性防御反应至关重要。越来越多的证据表明，氧脂素在植物中的总体生物学重要性与动物中脂质介质类花生酸家族的相当。
