氧脂素是一种脂类化合物,在植物对生物和非生物胁迫的反应中起信号作用。它们包括植物激素茉莉酸(JA)和相关的茉莉酸酯代谢物顺-(+)-12-氧代-植物二烯酸(cis-OPDA)、茉莉酸甲酯和茉莉酰基-L-异亮氨酸(JA-Ile)。除了防御反应外,茉莉酸还参与植物的生长和发育,并调节一系列过程,包括腺毛发育、生殖、根生长和衰老。已知顺式-OPDA具有不同于JA-Ile的信号传导作用。非酶促衍生的植物前列烷在结构上类似于顺式-OPDA,并诱导一组共同的基因,这些基因在拟南芥中对JA没有反应。双突变体和取食实验表明,cis-OPDA与脱落酸(阿坝)相互作用,抑制种子萌发,并增加阿坝不敏感5(ABI 5)蛋白的丰度,从而揭示了cis-OPDA在种子萌发调控中的新作用。在A. thaliana和所得到的化合物(称为异黄酮)被认为是顺式-OPDA的快速可用来源。
Oxylipins are lipid-derived compounds, many of which act as signals in the plant response to biotic and abiotic stress. They include the phytohormone jasmonic acid (JA) and related jasmonate metabolites cis-(+)-12-oxo-phytodienoic acid (cis-OPDA), methyl jasmonate, and jasmonoyl-L-isoleucine (JA-Ile). Besides the defense response, jasmonates are involved in plant growth and development and regulate a range of processes including glandular trichome development, reproduction, root growth, and senescence. cis-OPDA is known to possess a signaling role distinct from JA-Ile. The non-enzymatically derived phytoprostanes are structurally similar to cis-OPDA and induce a common set of genes that are not responsive to JA in Arabidopsis thaliana. A novel role for cis-OPDA in seed germination regulation has recently been uncovered based on evidence from double mutants and feeding experiments showing that cis-OPDA interacts with abscisic acid (ABA), inhibits seed germination, and increases ABA INSENSITIVE5 (ABI5) protein abundance. Large amounts of cis-OPDA are esterified to galactolipids in A. thaliana and the resulting compounds, known as Arabidopsides, are thought to act as a rapidly available source of cis-OPDA.
