Fold change of drought-responsive genes in maize under different treatments. Bars represent the relative expression (fold change) of selected drought-responsive genes under drought (D), biopriming (B), and combined drought + biopriming (DB) treatments, relative to control. Data is shown as mean ± SD of three biological replicates. Error bars indicate standard deviation. * indicates significant differences based on Tukey’s HSD test at P ≤ 0.05.
