摘要:

芳樟醇是一种重要的单萜类植物次生代谢物,广泛分布于植物的花、果、叶、茎和根中。其生物合成主要在质体内通过MEP途径完成,受到转录、表观遗传及转录后等多层次的分子调控。作为植物香气的关键成分,芳樟醇在植物与传粉昆虫、植食性昆虫及其天敌之间的生态相互作用中发挥着重要作用。此外,芳樟醇还参与植物对病原体和非生物胁迫的防御响应。本文中综述了芳樟醇的合成路径与调控机制,系统总结了其在吸引传粉者、抗病虫害及应对非生物胁迫等方面的研究进展,探讨其在植物适应复杂环境中的重要意义。同时,对芳樟醇在田间生态环境中的调控效应、单一对映体及衍生物的功能特异性、以及多重胁迫中的协同作用机制研究提出了展望,以期为园艺作物绿色农业应用提供理论支撑和技术指导。

Abstract:

Linalool is an important monoterpene secondary metabolite in plants,widely present in flowers,fruits,leaves,stems and roots. Its biosynthesis mainly occurs in plastids via the MEP pathway and is regulated by multiple molecular mechanisms,including transcriptional,epigenetic,and post-transcriptional controls. As a key component of plant aroma,linalool plays a significant role in the ecological interactions between plants,pollinators,herbivorous insects,and their natural enemies. In addition,linalool is involved in plant defense responses against pathogens and abiotic stresses. This review summarizes the pathways and regulatory mechanisms of linalool synthesis,providing a comprehensive overview of its ecological functions in attracting pollinators,resisting pests and diseases,and responding to abiotic stress. The review also explores the significance of linalool in plant adaptation to complex environments. Furthermore,it discusses the regulatory effects of linalool in field ecosystems,the functional specificity of individual enantiomers and their derivatives,and the synergistic mechanisms in response to multiple stresses,with the aim of providing theoretical support and technical guidance for the green agricultural applications of horticultural crops.

Key words: linalool, terpenoid secondary metabolites, biosynthesis, regulation, ecological function
