Fluorescence images of Arabidopsis transgenic plants carrying OsPR10a:GFP: a schematic diagram of OsPR10a:GFP::GUS fusion construct. b Induction of OsPR10a promoter by SA. OsPR10a:GFP::GUS was introduced into Arabidopsis by Agrobacterium-mediated transformation. Transgenic Arabidopsis seedlings carrying the OsPR10a:GFP::GUS was examined using fluorescence microscopy after SA treatment at 72 h. Non-transgenic Arabidopsis seedling was used as a control (left panel at mock and SA treatments). Shown are the bright-field images (upper panel Bright), the green fluorescent images using GFP filter (middle panel GFP) and the GFPA filter (bottom panel GFPA). Images are representatives from two independent experiments. The experiments were repeated at least twice
