Lack of K-Dependent Oxidative Stress in Cotton Roots Following Coronatine-Induced ROS Accumulation
Fig 6
Effects of COR treatment on superoxide anion (O2•-) (A) and hydrogen peroxide (H2O2) (B) concentrations in root tips as shown by NBT and DAB staining, respectively, under high K (2.5 mM) or low K (0.05 mM) conditions.
Emerging seedlings were grown in solution for 3DAKT and subsequently transferred to fresh solutions without (0 nM) or with (10 nM) COR. DAB and NBT staining of root tips were assessed at 8DACT (11DAKT). The photographs show representative plant roots from at least 8 plants analysed for each treatment.
