Research Advances in Metabolic Regulation,Storage and Transport of Carotenoids in Plants
Carotenoids are a group of natural pigments widely found in plants,which are generally composed of C40 terpenoids and their derivatives,which are connected from end to end of 8 isoprene units.In plants,carotenoids not only make plant organs appear color,but also perform important biological functions.In recent years,although the biosynthesis pathway of carotenoids is relatively clear,the mechanisms of metabolic regulation,including storage and transport of carotenoids in vivo are not yet understood.This paper briefly summarized the research progress of the biosynthesis,storage localization of carotenoids and terpenoid transporters,and focused on the potential substances that mediate carotenoid transport and the methods of identifying carotenoid transporters,in order to provide a better understanding of carotenoid synthesis and transportation.
