摘要:

类胡萝卜素(carotenoids)是一类在动物、植物和微生物中广泛存在的重要次生代谢物质,由链状或环状的亲脂性类异戊二烯构成,主要包括α-胡萝卜素、β-胡萝卜素、叶黄素等。植物类胡萝卜素作为天然色素,对于植物观赏品质的形成具有重要作用。同时,它也是植物光合辅助色素,可以帮助植物吸收太阳光能并转化为化学能,从而维持植物正常生长发育。此外,类胡萝卜素还是合成维生素A的前体,对人类营养健康有重要意义。植物类胡萝卜素生物代谢途径包含前体合成途径、类胡萝卜素合成途径和类胡萝卜素降解途径,对其中关键基因的功能解析有助于进一步理解植物类胡萝卜素代谢调控机制。本文全面梳理了植物类胡萝卜素生物代谢途径,系统总结了植物类胡萝卜素生物学功能的研究进展,特别是在植物光保护、园艺和农艺性状改良、抵抗非生物胁迫和参与植物激素信号调控中的重要功能。该综述为深入探究植物类胡萝卜素功能及其生物代谢调控机制提供理论基础,为加速分子设计育种提供了有价值的资源。

Abstract:

Carotenoids are a group of lipophilic isoprenoid metabolites, which are widely distributed in animals, plants, and microorganisms. It is demonstrated that α-carotene, β-carotene and lutein are the main components of carotenoids. In addition to influencing the ornamental quality of plants as natural pigments, carotenoids play a crucial function in photosynthesis. Moreover, they are also critically important for humans as precursors of vitamin A synthesis. The carotenoid metabolic pathway, including the precursor synthesis pathway, the biosynthesis and degradation pathway, is well established and has been widely explored in plants. With the intensive studies of carotenoid metabolism, the key genes and their functions have been identified, facilitating a deeper understanding of the regulatory mechanisms underlying plant carotenoid metabolism. This review focuses on the carotenoid metabolic pathway, with emphasis on recent progresses in biological functions of carotenoids, particularly in photoprotection, the agricultural and horticultural application, the resistance to abiotic stresses, and the regulation of plant hormone signaling. This review will offer a valuable information for the elucidation of carotenoids metabolism and facilitating selective molecular breeding.
