Physiological Characteristic Changes and Transcriptome Analysis of Maize (Zea mays L.) Roots under Drought Stress

Figure 3

KEGG pathway enrichment analysis of the DEGs after 5% PEG, 10% PEG, 15% PEG, and 20% PEG drought treatment, respectively. The experimental comparisons were based on the hypergeometric test, while the significance of the enrichment of the KEGG pathway is based on the value (). The “rich factor” shows the DEG ratio to the total gene number in specific pathways.
