Fig. 4From: Comparative transcriptomic analysis of maize ear heterosis during the inflorescence meristem differentiation stageComparison and functional enrichment of additive genes in hybrids. AÂ Top 20 enriched biological process GO terms in additive genes of the HY hybrid. BÂ All 10 enriched biological process GO terms in the CK hybrid. The Y-axis lists the enriched GO terms, and the X-axis represents the rich factor. The smaller the Q value, the higher the significance level and the closer to the red point. The more genes, the larger the circleBack to article page
