Correlations among TFs, genes, hormones, and H2O2. The expression of the genes, the contents of hormones and ROS were normalized by “Z-score”. a The expression patterns of MYB12, MYB44, CHS and FLS, which are involved in flavonoid biosynthesis. b The correlations among the expression of NAC19, NAC29 and NAC53, the contents of JA, ABA, and H2O2, which are involved in senescence processes. c The correlations among the expression of LSD1, LOL1, LOL2 and SOD. The number in each square represents the corresponding correlation coefficient. Color intensity is proportional to the correlation coefficient. Positive correlations are displayed in red and negative correlations in blue
