Venn diagram showing the profile of differentially expressed genes (DEGs). The differentiations were compared between inbred lines under each drought treatment, or between drought treatments in each inbred line. Drought treatments are labeled Control (C) and Drought (D). The tolerant line (YE8112) and the sensitive line (MO17) are labeled “T” and “S”, respectively. The four treatment-line biological samples are tolerant-control (TC), tolerant-drought (TD), sensitive-control (SC), and sensitive-drought (SD). Each compared combination is separated by an underscore (e.g., TC_TD). In the Venn diagram, the numbers of DEGs are shown across intersection areas among the compared combinations. In total we found 10,612 DEGs from all the areas. Four critical areas, labeled I, II, III, and IV, totally contain 5229 DEGs. Area I contains the tolerant treatment response DEGs, excluding others. Area II contains the line response under drought DEGs, excluding others. Area III contains both tolerance treatment response and line response under drought DEGs, excluding others. Area IV contains the treatment response DEGs within line.
