Fig. 3From: Hepatic transcriptome of the freeze-tolerant Cope’s gray treefrog, Dryophytes chrysoscelis: responses to cold acclimation and freezingHierarchical clustering and heatmap of hepatic transcripts differentially expressed among warm, cold, and frozen Dryophytes chrysoscelis. The columns represent liver samples and the rows represent differentially regulated transcripts (log2-fold change ≥|2|, FDR < 0.05). Data shown are count data transformed using the regularized-logarithm transformation [32].
