Comparison of photosynthetic properties in WT and tab2 cells. a Maximum quantum yield of PSII (Fv/Fm) determined in dark-adapted cells grown under N replete (WT solid circle, tab2 solid triangle) and N-depleted (WT open circle, tab2 open triangle) conditions. b Efficiency of PSII photochemistry in illuminated cells (ФII) under the conditions described above (more details are in “Methods”). c Non-photochemical quenching and d relative amount of oxidized QA determined in cells grown under N replete and N-depleted conditions. e, f The rates of oxygen uptake (respiration rate) and evolution were determined in WT and tab2 cells under N-depleted conditions (see legend above of N-depleted condition). Three biological replicates were included in the experiments, with error bars representing SE of the mean
