Phosphorus deficiency limits plant growth and development. To better understand the mechanisms behind how maize responds to phosphate stress, we compared the proteome analysis results of two groups of maize leaves that were treated separately with 1,000 µM (control, +P) and 5 µM of KH2PO4 (intervention group, -P) for 25 days. In total, 1,342 protein spots were detected on 2-DE maps and 15.43% had changed (P
