Temporal evolution of H₂O₂ and ${\mathrm{O}}_2^{-}$ accumulation in the leaves of wild‐type (WT) and transgenic Arabidopsis overexpressing miR359a (OEmiR359a) or LrGAMYB (OELrGAMYB) following Botrytis cinerea inoculation for 48 hr. Scale bar = 100 μm. (a) to (c) are stained with 3,3′‐diaminobenzidine and show the accumulation of H₂O₂; (d) to (f) are stained with nitroblue tetrazolium and show the accumulation of ${\mathrm{O}}_2^{-}$
