Expression heatmap of level of pear AP2, RAV, and Soloist genes. The expression levels of the AP2, RAV, and Soloist 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 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
