Gene Ontology (GO) analysis of the parental expression dominance genes. The y-axis is the percentages of genes mapped by the GO category terms: the percentages were calculated by the number of genes mapped to the particular GO category divided by the number of all genes. The x-axis is the GO category terms which were ordered by their relative abundance. The blue bars denote percentages for each category of all the annotated genes, and the red bars denote percentages of the GO categories of all the expressed genes detected in the studied leaf tissue (29,650 in total). The numbers inside the blue bars are the annotated genes in the specific GO categories. The enrichment FDRs (P-values) were given. ** Significant at the 0.01 statistic level. The GO analysis was performed both as an entirety and as distinct subgroups. (A1) All the parental expression dominance genes (6,572 in total) being considered as an entity; (A2) hose that showed additive expression (4,893 in total); (A3) those that showed non-additive expression (1,679 in total); (A3-1) those that showed non-additive expression in only one of the two generations (S4 or S5), that is, non-heritable (856 in total); (A3-2) those that showed non-additive expression in both generations (S4 and S5), that is, heritable (823 in total). (B1) The percentages of four GO annotation categories (all related to vesicle function) among all the parental expression dominance genes being considered as an entity; (B2) among those that showed additive expression; (B3) among those that showed non-additive expression; (B3-1) among those that showed non-additive expression in only one of the two generations (S4 or S5), that is, non-heritable; (B3-2) among those that showed non-additive expression in both generations (S4 and S5), that is, heritable.
