Figure 7
Heatmap showing the expression patterns of DREB subfamily genes in response to cold, heat, salt, and drought. Each row corresponds to a specific gene, and each column represents a stress condition. The color intensity indicates the level of gene expression (Log2 fold change): red for upregulation and green for downregulation, relative to the control condition. The heatmap was generated using the hcluster method of the R package amap66.
