Acyl-CoA-binding protein gene (ACBP) expression in Hordeum vulgare L. under hormone treatment and abiotic stress.Stress was induced by hormone treatment with indoel-3-acetic acid (IAA) at 0.15 µmol/L or abscisic acid (ABA) at 100 µmol/L or methyl jasmonate (MeJA) at 100 µmol/L, and ACBP expression was measured after 1, 3, 6, 12, and 24 h. Responses to abiotic stressors were measured 1, 3, 6, 12, and 24 h after treatment with 200 mM NaCl, 20% polyethylene glycol (PEG6000), or 30 µW/cm² UV radiation (growth lamp was turned off after 12 h of UV treatment, and no UV treatment was provided after 12 h). Cold and heat stress were applied via treatment at 4 °C and 42 °C, respectively. The expression levels of genes in the control were defined as “1”. The values are presented as the means of three replicates. “*” as significant at P ≤ 0.05, “**” as significant at P ≤ 0.01, “***” as significant at P ≤ 0.001
