The heatmap of DEGs in the liver. A-liver^c-A-liver^w: liver of −5°C Altay lambs (n = 5) compared to 20°C Altay lambs (n = 4); H-liver^c-H-liver^w: liver of −5°C Hu lambs (n = 6) compared to 20°C Hu lambs (n = 4); A-liver^c-H-liver^c: liver of −5°C Altay lambs compared to −5°C Hu lambs; A-liver^w-H-liver^w: liver of 20°C Altay lambs compared to 20°C Hu lambs. (a) A heatmap of top 50 DEGs. (b) A heatmap of candidate DEGs. The cluster analysis of gene expression is based on log2 FPKM data. The red color represents higher expression, and the green color represents lower expression.
