Fig. 2From: Transcriptome and metabolome analysis reveals key genes and secondary metabolites of Casuarina equisetifolia ssp. incana in response to drought stressHierarchical cluster analysis of common DEGs in C. equisetifolia leaves that were exposed to drought stress for different times. DEGs were selected based on a cut-off of P-adjust < 0.05 and |log2FC| ≥ 1. (a) Hierarchical cluster analysis of common DEGs in D_0 h vs. D_2 h and D_0 h vs. D_24 h. Red represents down-regulation and blue represents up-regulation of gene expression. Expression values were Z-scaled (log10 FPKM). (b) The expression patterns of six clusters. The blue line indicates the average expression values of all genes in the gene setBack to article page
