Comparison of the mRNA and protein expression levels for ten genes. Quantitative real-time PCR was performed using gene-specific primers (Additional file 1) and SYBR Green Supermix. The protein and mRNA log2 values for the ratios of treated samples to the corresponding controls (CK) are plotted. The relative gene expression was evaluated using the ΔΔCt method. D09, Chlorophyll a/b binding protein; D12, Class-1 LMW heat shock protein; C03, Ribulose-1,5-bisphosphate carboxylase subunit; C17, NAD dependent dehydratase; C18, Degp1; B05, ER-binding protein; B08, Transketolase; B15, Ribulose-1,5-bisphosphate carboxylase activase; A02, ATP synthase beta subunit; A06, Pyridoxal biosynthesis protein PDX1.
