Transcript abundance analysis for the various photosynthesis and stress-related genes in WT and OsHBP1b over-expressing plants under control and salinity. a Relative expression analysis of selected photosynthesis related genes such as ribulose bisphosphate carboxylase/oxygenase (RbcL), Photosystem I P700 chlorophyll a apoprotein A1 (PsaA), Photosystem II P680 chlorophyll a apoprotein A1 (PsbA), Light harvesting complex protein 2 (LHCP2), chlorophyllide a oxygenase (CAO) and P450 oxidoreductase (POR) in WT and OsHBP1b over-expressing plants. b Relative expression analysis of selected stress responsive gens (SOD, superoxide dismutase; APX, ascorbate peroxidise; CAT, catalase; bZIP, leucine zipper transcription factor; HSTF, heat shock transcription factor; HSP, heat shock protein; MT, metallothionine; DREB, dehydration responsive element binding protein; NAC TF, NAC domain containing transcription factors; P5CS, 2-pyrroline-5-carboxylate synthetase-2) in WT and OsHBP1b over-expressing plants. Expression analysis was done by quantitative real time PCR method. Expression of eEF gene was taken as reference and transcript abundance was calculated using 2^-ΔCT method. Error bars show standard error from triplicate experiments. Single asterisk show significant difference at p < 0.005 and double asterisk at p < 0.001
