摘要
臭氧是光化学污染的主要成分,其对全球生态环境尤其是对植物产生重要影响。花青素和类胡萝卜素是植物呈色密切相关的色素,臭氧影响植物花青素和类胡萝卜素的代谢已受到多方关注,本文从植物花青素和类胡萝卜素组分与功能、合成途径,植物吸收臭氧途径、特征,到臭氧影响花青素和类胡萝卜素合成调控的分子机制,系统地阐述植物在臭氧信号诱导下花青素和类胡萝卜素代谢途径中的调控作用,为深入揭示臭氧对植物生理功能的影响提供科学依据。
Ozone,which is the main component of photochemical oxidants,is a potential risk factor in global environment.Anthocyanins and carotenoids represent the major pigments in plants.Studies have been raised about effects of atmospheric ozone on anthocyanin and carotenoid of plants.This review provided an overview of anthocyanin and carotenoid components,functional roles,biosynthetic pathways,and ozone uptake by various plants.It also presented the molecular mechanisms underlying the anthocyanin and carotenoid biosysthesis responsing to elevated ozone.Our review revealed the regulation role of related genes in anthocyanins and carotenoids biosysthesis when exposed to elevated ozone,providing a theoretical basis for understanding the role of ozone in plant physiology.
