Fig. 4From: ATP Hydrolysis Determines Cold Tolerance by Regulating Available Energy for Glutathione Synthesis in Rice Seedling PlantsEffects of cold stress on carbohydrate, NAD(H) and NADP(H) contents in rice leaves. a, Carbohydrates; b, NAD(H) metabolism; c, NADP(H) metabolism. NSC, Non-structural carbohydrates; NAD(H), Nicotinamide adenine dinucleotide; NADP(H), Nicotinamide adenine dinucleotide phosphate. Vertical bars denote standard deviations (n = 4). A t-test was conducted to compare the difference between control and cold stress within a cultivar. * denotes P < 0.05Back to article page
