Photoprotection in the Antenna Complexes of Photosystem IIThe Role of Anthocyanins in Senescing Leaves

The carotenoid composition of higher plants is highly conserved the chloroplast encoded subunits of Photosystem I and Photosystem II core complexes bind β carotene whereas the outer antennae composed of nucleus encoded light harvesting complexes Lhc accommodate lutein neoxanthin and violaxanthin in moderate light whereas zeaxanthin is produced via de epoxidation of violaxanthin By acting as an optical screen that reduces the light capture of senescing chloroplasts anthocyanins provide an additional degree of photoprotection during the dismantling of the photosynthetic apparatus
