photoinhibitory

In contrast, the isiA - mutant exhibited a very low state-transition level and a substantial photoinhibitory quenching, as indicated by its poorly recovered Fm. To take a closer look at the state-transition defect of the isiA - mutant, the fast kinetics of the fluorescence induction of both the wild type and the isiA - mutant at different states were examined and plotted, as shown in

The wild type culture had an approximately 100% state transition, as indicated by the fast and full relaxation of Fm. Therefore, the photoinhibitory effect of such light intensity to the wild type is negligible.
