DREB genes induction rates in sesame roots during 3 days of drought stress in comparison to control condition. Transcripts abundance was quantified through qRT-PCR and the experimental values were normalized using sesame actin7 as reference gene. The mean values issued from three independent biological replicates were analysed for significance using the statistical t-test (p value <0.01). The histograms represent the relative expression values of induction rates (stress/control). The green bars represent the most up-regulated genes, the pink bars represent the genes moderately up-regulated and the red bars represent the down-regulated genes. * means significant 2-fold rate increase in gene expression (stress/control)
