Expression heatmap of pear ERF family genes at six developmental stages of fruit. The expression levels of AP2/ERF genes were measured by RNA-Seq analysis at six different stages: 15 DAF (S1), 36 DAF (S2), 80 DAF (S3), 110 DAF (S4), 145 DAF (S5), and 167 DAF (S6). The AP2/ERF gene family was subdivided into 12 groups: I, II, III, IV, V, VI, VI-L, VII, VIII, IX, X, and Xb-L. The color scale at the top right represents RPKM normalized by log2. Light green indicates a low expression level, gray indicates a medium level, and red indicates a high level. The graph was plotted in R using the heatmap.2 function
