Abstract：
Plant lipids are essential cell constituents with many structural, storage, signaling, and defensive functions. During plant-pathogen interactions, lipids play parts in both the preexisting passive defense mechanisms and the pathogen-induced immune responses at the local and systemic levels. They interact with various components of the plant immune network and can modulate plant defense both positively and negatively. Under biotic stress, lipid signaling is mostly associated with oxygenated natural products derived from unsaturated fatty acids, known as oxylipins; among these, jasmonic acid has been of great interest as a specific mediator of plant defense against necrotrophic pathogens. Although numerous studies have documented the contribution of oxylipins and other lipid-derived species in plant immunity, their specific roles in plant-pathogen interactions and their involvement in the signaling network require further elucidation. This review presents the most relevant and recent studies on lipids and lipid-derived signaling molecules involved in plant-pathogen interactions, with the aim of providing a deeper insight into the mechanisms underpinning lipid-mediated regulation of the plant immune system.
摘要：
植物脂质是必需的细胞成分，具有许多结构，storage,信令,和防御功能。在植物-病原体相互作用期间，脂质在先前存在的被动防御机制和病原体诱导的局部和全身水平的免疫反应中起作用。它们与植物免疫网络的各种成分相互作用，并且可以积极和消极地调节植物防御。在生物胁迫下，脂质信号主要与不饱和脂肪酸衍生的含氧天然产物有关，被称为氧化脂素；其中，茉莉酸作为植物防御坏死病原体的特定介质引起了极大的兴趣。尽管许多研究已经记录了氧化脂素和其他脂质来源的物种在植物免疫中的贡献，它们在植物-病原体相互作用中的特定作用以及它们在信号网络中的参与需要进一步阐明。这篇综述介绍了与植物-病原体相互作用有关的脂质和脂质衍生信号分子的最相关和最新研究。目的是更深入地了解支撑脂质介导的植物免疫系统调节的机制。
