氧脂素是由多不饱和脂肪酸的氧化断裂衍生的代谢物。这些代谢物在植物激素调节和防御中起着重要作用。在这里，我们调查的生产挥发性oxlipins在britectes和报告的生产高结构品种的C5，C6，C8和C9挥发性的苔藓。在苔类和金鱼藻氧化油脂的生产并不明显，在23筛选苔藓。一项生物合成研究表明，C18和C20脂肪酸都是挥发性氧脂素的前体，这些氧脂素主要在苔藓的绿色组织受到机械损伤后产生。(C)2009爱思唯尔有限公司保留所有权利。
Oxylipins are metabolites which are derived from the oxidative fragmentation of polyunsaturated fatty acids. These metabolites play central roles in plant hormonal regulation and defense. Here we survey the production of volatile oxylipins in bryophytes and report the production of a high structural variety of C5, C6, C8 and C9 volatiles of mosses. In liverworts and hornworts oxylipin production was not as pronounced as in the 23 screened mosses. A biosynthetic investigation revealed that both, C18 and C20 fatty acids serve as precursors for the volatile oxylipins that are mainly produced after mechanical wounding of the green tissue of mosses.
