氧化脂是植物类囊体膜上多不饱和脂肪酸氧化的产物,茉莉酸(JA)和12-氧代植物二烯酸(OPDA)等氧化脂在植物对光氧化胁迫的适应中起重要作用。OPDA既作为JA前体又作为诱导特定基因组表达的生物活性信号分子。这些基因可以诱导OPDA在JA-不敏感coronatininsensitive 1(COI 1)突变体,这表明有一个替代途径OPDA信号,独立于COI 1依赖的JA信号。然而,很少有人知道OPDA信号在光氧化应激反应。在这项研究中,我们分离的拟南芥突变体与组成型增强表达的OPDA-responsiveHsfA 2启动子。我们用缺失作图和互补分析鉴定了一个致病基因CATALASE 2。因此,我们的研究结果表明,ROS产生细胞代谢链接到OPDA信号。
Plant oxylipins derive from oxygenation of polyunsaturated fatty acids in thylakoid membranes and oxylipins such as jasmonic acid (JA) and 12-oxo-phytodienoic acid (OPDA) play important roles in adaptation to photo-oxidative stress. OPDA functions both as a JA precursor and as a biologically active signaling molecule that induces expression of a specific set of genes. These genes can be induced by OPDA in the JA-insensitivecoronatine insensitive1(coi1) mutant, suggesting that there is an alternative pathway for OPDA signaling, independent of COI1-dependent JA signaling. However, little is known about OPDA signaling in photo-oxidative stress responses. In this study, we isolated Arabidopsis mutants with constitutively enhanced expression from the OPDA-responsiveHsfA2promoter. We used deletion mapping and complementation analysis to identify one responsible gene asCATALASE2. Our results thus indicate that ROS-producing cellular metabolism links to OPDA signaling.
