Each spot corresponds to an individual gene, and the number of genes with a given ratio is plotted on the -axis. The colour of each spot is based on the relative expression in drought versus control (left panel); red, up-regulated; blue, down-regulated.<p><b>Copyright information:</b></p><p>Taken from "The relationship of drought-related gene expression in to hormonal and environmental factors"</p><p></p><p>Journal of Experimental Botany 2008;59(11):2991-3007.</p><p>Published online 13 Jun 2008</p><p>PMCID:PMC2504347.</p><p></p
