A, C and E correspond to C. arabica, C. canephora and C. eugenioides, respectively. Differential gene expression between the three species is indicated by the dashed-dotted lines for each gene expression category (gene expression in C. arabica deviated >1.25-fold from that of either parental species). The proportions of each category were compared between maturation stages (prop.test, 0.01 as the significance threshold P-value).
