Top 15 KEGG pathways sorted by P value for annotating DEGs in COS and LSW177. Of the DEGs identified in COS (a) and LSW177 (b) from KEGG pathway enrichment analysis for genes in different clusters, the top 15 pathways were selected according to the KO annotation for all DEGs involved in fruit ripening in COS or LSW177. Fisher’s exact test was used to identify the significance of the pathway in each profile (P) compared to the whole-transcriptome background. The P values were converted to -log10 and are presented in a heat map. Deeper color represents a higher degree of pathway enrichment
