Phenotypes of GO, GO-TSS, and GO-MS lines. A, Rosette phenotypes of plants grown at ambient atmospheric CO2 concentration (380 μL L−1) in different light conditions. wt, Wild type; μE, μmol quanta m−2 s−1. B, Glyoxylate content in leaf extracts of transgenic and wild-type plants. FW, Fresh weight. C, DAB staining of transgenic and wild-type leaves to assess H2O2 accumulation. Plants were grown for 14 d at 75 μmol quanta m−2 s−1 and transferred for 10 d to 200 μmol quanta m−2 s−1 during the light period. Brown deposits under bright-field illumination indicate the presence of H2O2 in all lines expressing GO.
