Fig. 3From: Two NADPH: Protochlorophyllide Oxidoreductase (POR) Isoforms Play Distinct Roles in Environmental Adaptation in RiceLevels of total Pchlide and photoactive Pchlide in WT, fgl, and the OPAO line. a Total Pchlide was measured based on fluorescence emission in pigments extracts from 10-day-old etiolated seedling grown in darkness. b Photoactive Pchlide levels were calculated by subtracting non-photoactive Pchlide from total Pchlide levels, which were measured in light-treated seedlings. The results were obtained and calculated from 10 independent etiolated leaves. The experiments were performed twice by fluorescence spectrophotometry, producing similar results. Letters a and b on the bars denote statistically significant differences based on Duncan’s test (P < 0.01)Back to article page
