• We investigated the regulation mechanism of cyclic electron flow around photosystem I (CEF-PSI) in the rice leaves which suffered from photosystem II (PSII) photoinhibition. High-light (HL) treatment [2000μmol photon m^<-2> s^<-1> at 0% carbon dioxide (CO_2), 2% oxygen (O_2) and 25℃] of rice leaves decreased both the maximum quantum efficiency of PSII (Fv/Fm) and the light-dependent O_2-evolution rate [V(O_2)]. High-light treatment did not affect the relative electron flux in PSI [(Φ(PSI)×PFD]. In non-treated leaves, increasing in the photon flux density (PFD) enhanced V(O_2), Φ(PSI)×PFD and the ratio of oxidized P700 to total P700 [(P700^+)/(P700)_<total>]. Φ(PSI)×PFD continued to increase even after the saturation of V(O_2) against PFD. These results suggested that the electrons not used for the major electron sink, photosynthetic carbon reduction-cycle, did turnover in PSI, that is, CEF-PSI functioned at a higher PFD. High-light treatments did not affect the activity of CEF-PSI and increased (P700^+)/(P700)_<total> in the lower PFDs, compared to non-treated leaves. The activity of CEF-PSI depends on the amount of oxidized PQ. Photoinhibition of PSII suppressed electron influx from PSII to photosynthetic linear electron transport. The enhanced (P700^+)/(P700)_<total> suggested the increase in the ratio of oxidized plastoquinone (PQ) to total PQ, which supported the activity of CEF-PSI in the photoinhibited leaves.
