Figure 7From: BYPASS1: synthesis of the mobile root-derived signal requires active root growth and arrests early leaf developmentROS is not increased in arrested bps1 leaves. (A). Hydrogen peroxide, visualized using DAB, was found in necrotic lesions and associated with vascular tissue, but it was not elevated in the bps1 leaf. (B) Superoxide, visualized using NBT staining, was found associated with vascular tissue, but it was not elevated in the bps1 leaf. Bars = 200 μm.Back to article page
