Cluster analysis of the SiHDZs expression profiles under drought stress. The heatmap was created based on the log2-transformed values of the relative expression levels of the SiHDZ genes under drought stress in drought-tolerant accession ZZM0635. The expression level is represented using color scale ranging from green (down-regulated) to red (up-regulated)
