e0“Low‐dose exposure to cadmium (20 μ m CdSO 4 for 48 h) reduced probability of electron transfer from plastoquinones to the terminal electron acceptors of PSI ( δ Ro ) accompanied by a decrease in the rate of P 700 + and PC reduction ( V red ) and the magnitude of the I 2 step on the DF kinetics”

Other claims from this paper (5)
- Intervention effect Cadmium reduced electron transfer probability from plastoquinones to terminal PSI acceptors.
- Intervention effect Cadmium decreased the rate of P700+ and PC reduction.
- Intervention effect Electron transport through PSI remained unchanged under cadmium exposure.
- Observation The authors proposed a possible cadmium inhibition site between PSII and PSI.
- Method / resource The authors proposed δRo, Vred and I2/I1 as indicators of early heavy-metal contamination.
