Distribution of differentially accumulated proteins (DAPs) following drought stress effects during waxy maize grain filling. A The number of DAPs at 10 dap and 25 dap are given. B Transcription factors (TFs) enriched in up- and down-regulated DAPs. The different color represented different level of log2(fold change). C KEGG pathway enrichment analysis of the up- and down-regulated DAPs [31]. The color scale at the bottom represents the significance (corrected P-value). Asterisks designate statistical (using Student’s t-test) significance P < 0.01
