KEGG enrichment of DEGs identified at 0 h vs. 4 h. (a) KEGG enrichment of DEGs between K0 (KL-0 h) and K4 (KL-4 h). The red boxes represent key pathways involved in the response to cold stress. (b) KEGG enrichment of DEGs between R0 (RB-0 h) and R4 (RB-4 h). The red boxes represent key pathways involved in the response to cold stress. (c) Heat map constructed based on the FPKM value of each gene of the key pathways
