Expression profiles of genes in selected GO categories.

<p>(<b>A</b>) Regulation of gene expression<b>;</b> (<b>B</b>) Protein modification process; (<b>C</b>) Protein folding; (<b>D</b>) Response to stress; (<b>E</b>) Nucleic acid metabolic process; (<b>F</b>) Proteolysis; (<b>G</b>) Carbohydrate metabolic process; (<b>H</b>) Oxidation-reduction process; (<b>I</b>) Cellular component organization; (<b>J</b>) Transmembrane transport. All of the genes regulated by temperature stress were submitted to functional annotation using DAVID software <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0037209#pone.0037209-Dennis1" target="_blank">[63]</a> (<a href="http://david.abcc.ncifcrf.gov/tools.jsp" target="_blank">http://david.abcc.ncifcrf.gov/tools.jsp</a>) and 10 representative biological process GO categories were selected. Genes exhibiting a fold change ≥3.0 in at least one sample were displayed. Columns and rows in the heat maps represent samples and genes, respectively. Sample names were displayed above the heat maps. Color scale indicates fold changes of gene expression. Genes that belong to more than one functional category were displayed only once.
