Functional analysis of DEGs based on the KEGG pathway.

<p>Pathways with a <i>Q</i>-value ≤ 0.05 significantly enriched in DEGs were analyzed in the comparison between treatment and control at the flowering stages. The degrees of KEGG enrichment can be measured by the richness factor, <i>Q</i>-value, and gene number enriched in this pathway. The right <i>y</i>-axis represents the KEGG pathway, and the <i>x</i>-axis shows the richness factor, which denotes the ratio of the number of DEGs to the number of annotated genes enriched in this pathway.
