Transcription levels of key genes and the activities of correspondingly encoding enzymes involved in anthocyanin synthesis in the peel of plum fruits treated at 20 °C and 35 °C for different time in the dark. Panel A–E, mRNA level; Panel F–J, enzyme activity assayed at 20 °C; Panel K–O, enzyme activity in 35 °C treated fruit for 9 days assayed at 20 °C and 35 °C. Each data point represents mean ± SE (n = 5). The asterisk indicates a significant difference between two temperature treatments at P < 0.05, t-test. PAL, phenylalanine ammonia-lyase; CHS, chalcone synthase; DFR, dihydroflavonol reductase; ANS, anthocyanidin synthase; UFGT, UDP glucose:flavonoid 3-O-glucosyltransferase. The same as below.
