Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis of differentially expressed genes (DEGs). a The top 20 enriched pathways of the DEGs between clones 12–23 and clone 15–28 under cold conditions (LL vs. HL). The X-axis indicates the enrichment factor on a scale from 0 to 0.7. The dot colour and size indicate the q-value and gene number as shown on the right. b Heat map of input number and background number of the KEGG enriched pathways of the DEGs of clones under cold conditions (LL vs. HL). The left colour panels display the input number of each term from 11 to 125, and the right colour panels display the background number of each term from 16 to 393. c Heat map of the KEGG enriched pathways of the DEGs of the pairwise comparisons LL vs. LC and HL vs. HC. Colour panels display the P-values of each term from 0 to 0.76
