Abstract
The control over photosynthetic electron transport in isolated wheat thylakoids was unevenly shared by electron carriers engaged in the process. Electron carriers in the vicinity of photosystem 2 (PS2) assumed a higher control over the process than other carriers. A shift of the control from the reducing side of PS2 in cool-grown plants to the oxidizing side of PS2 in warm-grown plants was observed. This shift indicated that the distribution of fractional control over photosynthetic electron transport was influenced by growth temperature.
