Fig. 6From: Comparative transcriptome analysis reveals important roles of nonadditive genes in maize hybrid An’nong 591 under heat stressHierarchical clustering of the 60 differentially expressed genes enriched in the GO term response to heat. The heatmap was drawn with the R package pheatmap. The color scale at the right of the figure indicates the gene expression levels transformed by log10 (FPKM + 1)Back to article page
