植物类胡萝卜素生物代谢途径及其功能研究进展
Research Progress in the Biological Metabolic Pathway and Functions of Plant Carotenoids
摘要
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.关键词
