Contributions of the three allelic expression types of genes to the differentially expressed genes (DEGs). (A) The mid-parent heterosis level of total biomass at the secondary branch differentiation stage exhibited by the three F1 hybrid populations. Heterosis was evaluated using the fresh weight and dry weight of single plants from each F1 hybrid generation and their parents. (B) The preferential allelic expression genes compared between each F1 hybrid and its parents. (C) The percentages of DEGs represented by the genes of each allelic expression type. (D) The contributions of monoallelic expression, preferential allelic expression, and biallelic expression genes to the total genes and DEGs in the three F1s. (E) The proportions of genes with monoallelic expression, preferential allelic expression, and biallelic expression profiles in the F1 generation compared with their parents, sub-grouped according to fold differences in expression level. (F) The proportions of monoallelic expression, preferential allelic expression, and biallelic expression genes expressed in the F1 generation and one of the two parents but not expressed in the other parent.
