PSI photoinhibition and protection at low temperatures and in fluctuating light: An 30 ecophysiological vista

In green leaves in vivo, photosystem I (PSI) was thought to be resistant to photoinhibition. In 1994, it was found that, in chilling-sensitive plants such as cucumber (Cucumis sativus L.), exposing leaves to moderate constant light at temperatures below 10 degrees C induces PSI photoinhibition with little effect on PSII. Since the beginning of this century, PSI photoinhibition induced by…
