SiWRKY gene expression in sesame roots treated for 8 h with waterlogging stress compared with untreated controls. Transcript abundance was quantified using quantitative real-time polymerase chain reaction (qRT-PCR) and expression levels were normalized using sesame β-actin (SIN_1009011) as a reference gene. The mean expression levels from three independent biological replicates were analyzed for significance using t-tests (p < 0.01). The histograms represent the relative expression levels and rates of gene induction (stress/control). An asterisk (*) indicates a significant (2-fold) increase in gene expression in plants treated with waterlogging stress compared with untreated controls
