Relative expression level of expansin (exPA1) in wheat plants inoculated with different Bacillus strains grown under cold stress and at regular temperature (A), Relative expression level cytokinin encoding gene (CKX2) (B) Relative expression level of ethylene encoding gene (ERF) (C) Relative expression level Auxin (ARF) encoding gene (D). The error bars on the graphs indicates the standard deviation of the mean (n = 3). The significant difference between the treatments was observed at p ≤ 0.05 by using Tukey’s HSD test. The expression analysis was done three times with similar results.
