Experimental design, gene differential expression and hierarchical clustering of differentially expressed genes. a Phenological stages considered for the transcriptomic study. RNA samples were obtained from large (LB) and small (SB) berry genotypes, at phenological stages of fruit-setting (FST) and berry 6–8 mm stages (B68), modified from [15]. b Differentially expressed genes after comparison between RxS segregants with contrasting phenotypes for berry weight in both phenological stages. c Hierarchical clustering of a group of 526 differentially expressed genes among LB and SB segregants in the FST and B68 stages. Pearson correlation was used as distance and five clusters were identified
