  1. AASC, Amino acid sequence coverage; Protein spot ID refers to numbers in Fig. 1a-b. 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. NE, Non Expression. SMC, soil moisture content. athe same protein spots identified at different stages
