Analysis of the relative expression levels of the main structural genes and the transcription factor MYBs related to the flavonoid biosynthesis pathway in RL and GL. CHS, chalcone synthase; CHI, chalcone isomerase; F3H, flavanone 3β-hydroxylase; F3H, flavonoid 3′-monooxygenase; DFR, dihydroflavonol 4-reductase; ANS, anthocyanidin synthase; UFGT, flavonoid 3-O-glycosyltransferase; FLS, flavonol synthase. McMYB4, McMYB10, and McMYB16 are R2R3 transcription factors in crabapple. The data shown are the mean ± SD. ** and * indicate significance at P < 0.01 and P < 0.05 by t-test, respectively.
