Functional enrichment analysis for dominant genes. a Significant GO terms of dominant genes in reciprocal crosses. Each dot represents a GO term, and the size of a dot represents the number of genes enriched in the GO terms. The shade of the colored dots indicates the level of significance of the GO terms. The names of GO terms in purple, blue and brown represent the GO terms that belonged to molecular function, cell composition and biological process, respectively. b and c KEGG pathway analysis for dominant genes in the CR and RC groups, respectively. Each dot represents a KEGG pathway, and the size of a dot represents the number of genes enriched in the pathway. The color of a dot represents the KEGG classification in the pathway. The dashed red lines indicate significance levels (adjusted P-value < 0.05). The dots that passed dashed red lines are regarded as significant pathways
