Gene expression patterns of COG categories. Two functional categories of genes showing the most changes in gene expression are represented as red boxes. Nine functional categories of genes that showed moderate changes in gene expression are represented as yellow boxes. The other nine functional categories of genes that showed little changes in gene expression are represented as blue boxes. Inset figure at the upper right of each functional category of genes indicates the control (untreated). Colored lines and text indicate the representative genes of each COG category. Y-axis represents fold-change and is fixed at the value of 10
