Photoinhibition of Photosystem I at chilling temperatures was investigated. Illumination of barley and cucumber leaves at 4°C induced a lowered Photosystem I activity. In barley, the reaction centre proteins PSI-A and PSI-B were both partially degraded as was the nuclear-encoded PSI-D polypeptide. Barley leaves infiltrated with KCN to increase oxidative stress, showed increased photoinhibition of Photosystem I, including reduced photochemical activity and marked degradation of several… CONTINUE READING
