Expression profiles of MdMATE genes in different tissues/organs and developmental stages. A. Heatmap of the expression pattern in various tissues/organs and developmental stages. The name of tissues/organs and development stages are indicated on the right. WAF: week after full bloom. The FPKM values were transformed by log2. Phylogenetic tree on the top of heatmap is the same as Fig. 2A. B. Spearman correlation of gene expression pattern. Positive correlations are displayed in red and negative correlations in blue. Size and color intensity of the square are proportional to the value of Spearman’s ρ. Red and yellow lines on the top of correlation heatmap indicate segmental and tandem duplicated pairs, respectively
