Fig. 8From: Improving the anthocyanin accumulation of hypocotyls in radish sprouts by hemin-induced NOEffects of different treatments on the activities of key NO biosynthesis enzymes and encoding genes. A and B The enzyme activities of NR (A) and NOS (B) in radish hypocotyls. C and D The relative expression levels of NIA1 (C) and NOA1 (D) in radish hypocotyls. RsActin was used as internal control. The values were means ± standard deviation (SD) of the three independent experiments with at least three replicates for each. Different letters indicate significant differences among treatments (P < 0.05)Back to article page
