The mutation of Ntε-LCY genes reduced the accumulation of reactive oxygen species in leaves to different extents after exposure to normal light or high light stress in WT, ntε-lcy2-1, and ntε-lcy1-1 lines. a In situ O2− production in 1-cm leaf discs by NBT staining (n = 12). b Total H2O2 content of WT and ntε-lcy lines after exposuring to normal light or high light stress. Data are presented as the mean ± SEM of three independent experiments (n = 3, *p < 0.05; two-way ANOVA, Tukey’s post-hoc test)
