Daily change patterns in anthocyanin content, and the expression patterns of anthocyanin late biosynthetic genes (ALBGs) and a typical anthocyanin transport gene, PbGSTF12, in ‘Red Zaosu’ pear fruit skin. (a) The anthocyanin content in the fruit skin of ‘Red Zaosu’ over three continuous days. Images show the ‘Red Zaosu’ phenotypes at three time points over the three continuous days. (b) The expression patterns of ALBGs and PbGSTF12 in ‘Red Zaosu’ fruit skin over three continuous days. The gray boxes indicate nighttime. The NCBI accession numbers of the ALBGs and PbGSTF12 are listed in Supplementary Table S1. HAS: hours after sunrise of day 1. Error bars represent the standard errors (SEs) of the means (n = 3). Data in (a) was determined using a one-way analysis of variance (p < 0.05); the significant differences are indicated by different lowercase letters.
