The photodamage and protective role of pheophytin a in the photosystem Ⅱ reaction center against light-induced damage

【摘要】 <正> Light is the only energy source for photosynthesis, but excess light energy is harmful toplants. During the recent years, especially since the preparation of PS Ⅱ (PS Ⅱ) reactioncenter D1/D2/Cyt b-559 complex in 1987 by Nanba and Satoh, the molecular processes ofphotoinhibition have been intensively studied and great development has been made. Thedetailed mechanism of photoinhibition has been an important topic.更多还原
