Activity of TaGAPC1 promoter after PEG8000, ABA and H2O2 abiotic stresses. a cis-elments of TaGAPC1 promoter. b Histochemical staining of TaGAPC1 promoter in transiently transformed tobacco leaves. P: positive control (CaMV 35S promoter); WT: wild type. c Analysis of RLUC activity for TaGAPC1 promoter in transiently transformed tobacco leaves in response to stress. Error bars indicate ±SD (n = 3, from three technical replicates). Significant differences were assessed with one-sided paired t-tests (*, P < 0.05; **, P < 0.01). Three biological experiments were performed, which produced similar results
