园艺作物挥发物合成及其生物学功能研究进展

Research progress on the synthesis and biological function of horticultural crops volatiles

植物挥发物作为其重要的次生代谢物,主要包括绿叶挥发物、萜类挥发物和苯环类化合物,对调节植物-植食性昆虫-天敌间的三级营养关系具有重要意义。研究其合成调控机理,对探索其在植物防御以及生长发育上的应用具有重要的指导意义。园艺作物挥发物是影响其品质、功能性及病虫害绿色防控的重要成分。为此,本文对园艺植物挥发物的种类、合成途径以及调控机制方面进行了综述,并阐述了其生物学方面的功能及其应用前景。

Plant volatiles as important secondary metabolites of plants,mainly include green leaf volatiles,terpenoids and benzene ring compounds,which play an important role in regulating the tertiary nutritional relationship among plant,herbivorous insects and predators.Dissecting mechanism of synthesis and regulation of plant volatiles has important guiding significance for exploring its application to plant defense,growth and development.Volatiles in horticultural crops were important components which affect the quality,biological function and environmental friendly pest and pathogen control.Here,the types,synthesis pathways and regulatory mechanisms of volatiles were reviewed,and its biological function and application prospects are stated as well.
