Table 3 Proteins whose expression were significantly higher expressed (+) in XZ5 compared with XZ54 leaves under control condition (XZ5 vs XZ54)AASC, Amino acid sequence coverage; Protein spot ID refers to numbers in Fig. 1. Accession number of top database match from the NCBInr database. Fold increase and decrease were calculated as drought/control, and –control/drought for up and down -regulated proteins respectively. All ratios shown are statistically significant (p < 0.05). +10⁶ and -10⁶ referred to the specific expressed and totally inhibited proteins, respectively
