Changes in global expression levels between hybrids and their parents. (A) Differential expression analysis was performed between APE and expression in hybrids. The black line indicates that the genes related to APE were ordered by their normalized, standardized expression intensity. Orange scatter points represent up-regulated expression in hybrids, and green scatter points represent down-regulated expression in hybrids. Gradual increases and decreases in the number of DEGs were observed from F1 to F3. (B) The distribution of shared DEGs was observed in the liver of reciprocal cross hybrids in a differential expression analysis between APE and expression in hybrids. (C) Seven shared DEGs were observed between BT and TB; these genes were all down-regulated. (D) Module of 12 expression patterns represents the change in gene expression state between the two inbred parents and their hybrid offspring. (E) Distribution of expression divergence of each parent relative to the hybrid offspring in three generations of BT and TB, with the TC comparison on the x-axis, the BSB comparison on the y-axis, and colors corresponding to pattern I to pattern XII.
