The Xanthophyll Cycle in Green Algae (Chlorophyta): Its Role in the Phptosynthetic Apparatus

Popis výsledku v původním jazyce

Light dependent conversion of violaxanthin to zeaxanthin, so called xanthophyll cycle was shown to serve as a major, short-term light acclimation mechanism in higher plants. The role of xanthophylls in thermal dissipation of surplus excitation energy wasdeduced from the linear relationship between zeaxanthin formation and the magnitude of nonphotochemical quenching. Unlike in higher plants, the role of xanthophyll cycle in green algae (Chlorophyta) is ambiguous since its contribution to energy dissipation can significantly vary among species. Here, we have studied the role of the xanthophyll cycle in the adaptation of several species of green algae (Chlorella, Scenedesmus, Haematococcus, Chlorococcum, Spongiochloris) to high irradiance. The xanthophyll cycle has been found functional in all tested organisms; however its contribution to nonphotochemical quenching is not as significant as in higher plants. This conclusion is supported by three facts: (i) in green algae the content of...
