  1. AASC, Amino acid sequence coverage; Protein spot ID refers to numbers in Fig. 1c-d. 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). +10000 and -10000 referred to the specific expressed and totally inhibited proteins, respectively. NE, non expression. a the same protein spots identified at different stages
