In plants, carotenoid accumulation and sequestration take place within chloroplasts and chromoplasts. In the chloroplast, practically all carotenoids are associated with chlorophyll-binding proteins, whereas chromoplasts have developed a unique mechanism to sequester carotenoids within specific lipoprotein structures. Recent research into the existence of a group of homologous genes that encode carotenoid-associated proteins that aid in the generation of carotenoid-lipoprotein structures in chromoplasts, offers a new framework for elucidating the carotenoid sequestration mechanism.
