Multifaceted analyses disclose the role of fruit size and skin-russeting in the accumulation pattern of phenolic compounds in apple
Fig 6
The correlation between the expression pattern of the 16 genes together with the total phenolic content and fruit size (defined by diameter and weight) is presented for both pulp (a) and skin (b) tissues, respectively. The correlation value is indicated by color (blue for positive correlation and red for negative correlation), while the magnitude of correlation is indicated two-fold, with the size and color intensity of the dots in the upper-right part of the plot and with numbers in the lower-left part of the plot. For each plot, the numerical code in the diagonal stands for 1: total phenols, 2: PAL, 3: CHS, 4: CHI, 5: F3H, 6: DFR, 7: ANS, 8: UFGT, 9: ANR, 10: PPO, 11: FLS, 12: LAR, 13: C3H, 14: ENRL-3-5, 15: UGT88F1/4, 16: UGT71K1s, 17: UGT71A1s1, 18: fruit diameter, 19: fruit weight.
