Localization of Screening Pigments Within Plant Cells and Tissues
Subcellular localization and distribution within tissues are crucial characteristics of plant screening pigments. General patterns of the localization and distribution of screening compounds in plant tissues are discussed in connection with their function, chemical properties, and biosynthetic origin. Special attention is paid to the vacuolar and cuticular phenolics and extrathylakoid carotenoids deposited in oil bodies of microalgae and plastoglobuli of higher plants.
