Figure 2

Hierarchical cluster analysis of significantly differentially expressed ZM4 genes for normal and ethanol stress condition at 24 h. Gene expression values were clustered based on their log2 based expression values. Negative numbers (colored red) indicates less relative gene expression under normal condition, and positive numbers (colored green) indicate greater relative gene expression under ethanol stress.
