Table 4. Fold-change (Log2FC) for plant hormones and related compounds levels in herbicide-tolerant GM maize variety (NK603) and its non-GM near-isogenic variety in different comparisons of Experiment 1 and 2.

A positive value indicates that the compound showed upregulation for the first treatment of the comparison. A negative value indicates that the compound showed downregulation for the first treatment of the comparison. ‘ns’ indicates that no significant difference was found (ANOVA P < 0.05) for the levels of this compound on that specific comparison.
