Proteomic analysis of differentially expressed proteins in sugarcane. PCA of expressed protein (a); x- and y-axes indicate the first and second principal components, respectively. Bar chart of differentially expressed proteins (b); red and blue represent upregulated and downregulated proteins, respectively. KEGG pathway enrichment analysis of proteins at different growth stages of GF98-296 and GT42 (c), was performed using the KEGG software of the Kanehisa laboratory
