Expression profile of genes encoding differentially represented plastid proteins in drought stressed (a) and drought-recovered (b) plants, as deduced from proteomic analysis. Transcript level was determined by qRT-PCR after normalization to the elongation factor1-α (EF-1-α) gene as 2^−ΔΔCt. Error bars indicate SD, n = 3. Significant differences were analysed by Student’s t test (^* P ≤ 0.05, ^** P ≤ 0.01). C control, D drought-stressed, CR control-recovered, DR drought-recovered plants
