研究背景短链氧脂素（oxylipins）作为植物体内主要的挥发性有机碳，在植物天然免疫中发挥着重要作用，但作为藻类防御信号的作用尚未得到深入研究，也远未被确立。1-辛烯-3-醇的产生可以作为信使，诱导坛紫菜处于引发状态，并通过上调甲基茉莉酸、吲哚-3-乙酸和赤霉素A3的合成来准备防御。这些oxlipins的生产也调整细胞中的氧化还原状态，导致主机防御activation.ConclusionsWe提供的第一个演示，1-辛烯-3-醇从P. haitanensis，可以作为一个自我刺激的社区信使。1-辛烯-3-醇的多重作用可以解释为什么坛紫菜，一个非常古老的植物界的谱系，在潮间带的生态位中茁壮成长。
BackgroundShort chain oxylipins in plants as the main volatile organic carbon have been speculated to playing an important role for plant innate immunity, however, not yet intensively studied and far away established as the fully recognized algae defense signals.ResultsThe production of 1-octen-3-ol is self-amplified via the fatty acid-oxylipin metabolic cycle through positive feedback loop. Production of 1-octen-3-ol may act as a messenger that induces P. haitanensis to be in a primed state and ready for defense by upregulating the synthesis of methyl jasmonic acid, indole-3-acetic acid, and gibberellin A3. Production of these oxylipins also adjust the redox state in cells, resulting in host defense activation.ConclusionsWe provide the first demonstration that 1-octen-3-ol from P. haitanensis, can act as a self-stimulating community messenger. The multiple effects of 1-octen-3-ol may explain why P. haitanensis, a very ancient lineage within plant kingdom, thrives in the niche of intertidal zones.
