Fig. 2: Evaluating the correlation of the candidate WRKY genes with anthocyanin biosynthesis and transport-related genes in ‘JinZheng No. 1’ and ‘Starkrimson’ pear cultivars.

a The appearance of the ‘JinZheng No. 1’ and ‘Starkrimson’ pears at 30, 60, and 90 DAFB. b Determination of the anthocyanin contents in the ‘Starkrimson’ and ‘JinZheng No. 1’ pears at 30, 60, and 90 DAFB. c The expression level was analyzed by RT-qPCR for anthocyanin metabolic structural and regulatory genes. Significant differences are indicated at the level of P < 0.05 with lowercase letters. Highly significant differences are shown with uppercase letters (P < 0.01). Error bars are shown with the three biological replicates
