Karotenoidi v fotosinteznem aparatu in odziv na stres

Abstract

Carotenoids are tetraterpenes which are exclusively located in chloroplast and chromoplast. Within the chloroplast, carotenoids have important roles in light-harvesting, photoprotection and stress response. Carotenoids in chloroplast are reviewed in this paper. The importance of carotenoids in plants under stress is discussed. The role and function of xantophyll cycle in plants under stress is pointed out.
