Fig 2. Enrichment analysis of 20 differentially expressed proteins of herbicide-tolerant GM maize variety (NK603) and its non-GM near-isogenic counterpart under control and stress conditions (drought and herbicide application).

The analysis was performed using the online tool agriGO v1.2, using Single Enrichment Analysis (SEA) with the following parameters: 1) Selected species: Zea mays ssp; 2) Statistical test method: Hypergeometric; 3) Multi-test adjustment method: Hochberg (FDR); 4) Significance level of 0.05; 5) Minimum number of 5 mapping entries; and 6) Gene ontology type: Plant GO Slim.
