Fig 3

Levels of SA, MeJA, CA, JA, ABA and AIA in leaves of herbicide-tolerant GM maize (NK603) variety and its non-GM counterpart under control and drought stress conditions. Compound levels were considered significantly different at ANOVA P < 0.05. When significant, lowercase letters represent the horizontal comparisons in each compound from the Stress factor (non-GM D x non-GM; GM D x GM). Uppercase letters represent the vertical comparisons from the Genetic Modification factor (GM x non-GM; GM D x non-GM D)
