The pairwise correlation coefficients between the expression levels of anthocyanin-related TFs and those of ALBGs in the fruit skin of ‘Red Zaosu’ pear over three continuous days. The NCBI accessions of the anthocyanin-related genes are listed in Supplementary Table S1. The significant correlation coefficients are indicated in bolded values. The data was analyzed using SPSS 20. *: Correlation significant at the 0.05 level (p < 0.05, two-tailed); **: Correlation significant at the 0.01 level (p < 0.01, two-tailed).
