Determination of nonenzymatic antioxidants in Arabidopsis WT and mutant plants

Nonenzymatic antioxidant	WT	∆2cp	ntrc	ntrc-∆2cp
AsA+DHA (μmol⋅g⁻¹ FW)	3.806 ± 0.207	3.675 ± 0.260	3.334 ± 0.225	3.571 ± 0.276
AsA/(AsA+DHA)	0.914 ± 0.019^*	0.922 ± 0.026^*	0.829 ± 0.017^†	0.883 ± 0.016^*^†
GSH+GSSG (μmol⋅g⁻¹ FW)	0.924 ± 0.041	0.944 ± 0.064	0.890 ± 0.056	0.918 ± 0.032
GSH/GSH+GSSG	0.879 ± 0.027^*	0.856 ± 0.023^*	0.796 ± 0.025^†	0.851 ± 0.035^*^†

Whole rosettes (n = 5) of 6-wk-old plants grown under short-day photoperiod were harvested to determine AsA, DHA, GSH, and GSSG (Materials and Methods). For the indicated lines, total ascorbic acid (AsA+DHA), reduced ascorbic acid /total ascorbic acid (AsA/AsA+DHA) ratios, total glutathione (GSH+GSSG), and reduced glutathione/total glutathione (GSH/GSH+GSSG) ratios are presented as mean values ± SE from two independent experiments combined.
