... reduction of Q A in DCMU-inhibited PSII is accounted for by the O–J phase. Interestingly, this decrease of A J–I was compensated for by the equivalent increase of A O–J , making the sum of contri- butions ... from thylakoid membranes. Such analysis is needed for a a more thor- ough use of FI in the study of PSII electron transport and to obtain a more complete analysis...
