KEGG enrichment analysis of DEGs at the same freezing stress between two cultivars. KEGG pathway classifcation of DEGs under cold stress in ‘Dongzao’ and ‘Jinsixiaozao’, respectively. The Y axis corresponds to KEGG pathway, the X axis shows the enrichment ratio between the number of DEGs enriched in a particular pathway. The color of the dot represents q-value, and the size of the dot represents the number of DEGs mapped to the referent pathway
