Differential gene expression and metabolic pathway changes between leaves and fruits in P. avium. A Differentially expressed genes. Two vertical lines indicate gene expression fold change (leaf vs fruit) > 2 and < 0.5 and the horizontal line indicates the adjusted P value of 0.05. Genes with significant differential expression (FC_P) are indicated by red dots (up-regulated and down-regulated); genes with no significant differential expression (NS) are represented by black dots; genes with differential expression and p-value > 0.05 (FC) are indicated by blue dots (up-regulated and down-regulated). B Heatmaps of edible cherry selective candidate differentially expressed genes. Among them, R_leaf, L_leaf, B_leaf and L_fruit, R_fruit, B_fruit refer to gene expression levels for leaves and fruits from three distinct P. avium cultivars (‘Bing’, ‘Lapins’ and ‘Rainier’). C–E DEGs involved in main sugar metabolic pathways in P. avium (leaf vs fruit). C Starch and sucrose metabolism. D Fructose and mannose metabolism. E Pentose phosphate pathway. Enzymes regulated by key DEGs are highlighted in yellow; Enzymes regulated by genes without significant differential expression are highlighted in blue
