摘要
昆虫取食作为一种重要的生物胁迫广泛存在于自然界中。目前,昆虫取食所诱导的植物防御反应已成为研究热点。1-戊烯-3-酮(1-penten-3-one)作为昆虫取食诱导产生的挥发性小分子酮类物质,因含有α,β-不饱和羰基结构,对植物直接和间接的防御反应具有重要作用。本文较系统地综述了1-戊烯-3-酮在植物防御反应中的作用及机理,特别对H_2O_2、Ca^(2+)、H^(+)跨膜分子、离子流在植物识别1-戊烯-3-酮过程中的初始信号功能、下游防御相关基因表达模式进行了详细分析,指出了研究中存在的问题,对未来的研究方向和重点科学问题提出了建议,以期为1-戊烯-3-酮诱导防御反应的深入研究提供参考。
Herbivores wounding,as an important biotic stress,widely exists in nature.Plant defense response induced by insect feeding has become a hot research area.As a kind of volatile small molecule ketones induced by insect feeding,1-penten-3-one plays an important role in both direct and indirect plant defense responses because of itsα,β-unsaturated carbonyl structure.In order to illustrate its defense mechanism in Arabidopsis thaliana response to 1-penten-3-one,the initial signaling events,such as transmembrane H2O2,Ca2+and H+fluxes,and the expression patterns of downstream defense-related genes were particularly reviewed.The existing problems in the research field were pointed out,and suggestions on future research directions and key scientific issues were given.This review may assist further studies of the defense responses induced by 1-penten-3-one.
