Heatmaps of turquoise and blue modules in rice under drought stress.

<p>The x-axis represents microarray samples grouped into drought treated and control samples and y-axis represents genes found in the module. Below the heatmap the corresponding module eigengene expression values are shown. The most significant functional terms found in the module are also shown. The number of genes found in each module and the percentage of up and downregulated genes in each module are shown as a pie chart.
