Improving wheat drought stress tolerance is a critical and challenging task, more research necessary since many parts of the world depend on this crop for food feed. Our current work focused influence probiotic microorganisms in combination with calcium salts physiological biochemical metabolic pathways that uses when exposed to analysis gene expression levels contribute tolerance. The was conducted laboratory under controlled conditions, simulating prolonged drought. Seedlings were treated different (Bacillus subtilis, Lactobacillus paracasei, some yeast) 105 CFU/mL concentrations seed priming later same concentration seedling spraying. A total 70 g/m2 CaCO3 or 100 CaCl2 added soil before sowing seeds. Almost all tested treatments improved plant growth positively affected resistance winter wheat. Bacillus salts, had greatest effect maintaining relative leaf water content (RWC). proline, malondialdehyde (MDA), H2O2 tests proved significant positive impact plant’s response at level, parameters close those irrigated plants, example, ones B. subtilis alone Ca lowest content, 0.86–0.96 μmol g−1 FW, compared 3.85 FW Control, along lower drought-induced expression. All presented results show statistically differences (p < 0.05). This study showed can activate plants’ defense reactions practical significance these ecological measures be useful field conditions.
