Many organisms use fatty acid derivatives as biological regulators. In plants, for example, fatty acid-derived signals have established roles in the regulation of developmental and defense gene expression. Growing numbers of these compounds, mostly derived from fatty acid hydroperoxides, are being characterized. The model plant Arabidopsis thaliana is serving a vital role in the discovery of fatty acid-derived signal molecules and the genetic analysis of their synthesis and action. The Arabidopsis genome sequencing project, the availability of large numbers of mutants in fatty acid biosynthesis and signal transduction, as well as excellent pathosystems, make this plant a tremendously useful model for research in fatty acid signaling. This review summarizes recent progress in understanding fatty acid signaling in A. thaliana and highlights areas of research where progress is rapid. Particular attention is paid to the growing literature on the jasmonate family of regulators and their role in defense against insects and microbial pathogens.
许多生物体将脂肪酸衍生物用作生物调节剂。例如，在植物中，脂肪酸衍生的信号在发育和防御基因表达的调控中已确立了作用。越来越多这类化合物（大多源自脂肪酸氢过氧化物）正被鉴定出来。模式植物拟南芥在脂肪酸衍生信号分子的发现及其合成与作用的遗传分析中发挥着至关重要的作用。拟南芥基因组测序项目、大量脂肪酸生物合成和信号转导突变体的可得性，以及出色的病理系统，使这种植物成为脂肪酸信号研究中极为有用的模式。本综述总结了在理解拟南芥脂肪酸信号方面的最新进展，并突出了进展迅速的研究领域。特别关注了关于茉莉酸类调节剂家族及其在抵御昆虫和微生物病原体方面作用的不断增多的文献。
