Phenotypes of noe1 were complemented by NOE1/OsCATC. A, Phenotypic comparison among 3-month-old wild-type (WT), noe1, and complemented transgenic noe1-C plants. B to D, Total extractable leaf catalase activities and H2O2 and SNO contents in 3-month-old wild type, noe1, and noe1-C plants grown under high light (1,600 μmol m−2 s−1). These data were obtained from three independent replicates. FW, Fresh weight.
