Fig. 3From: Actin filaments mediated root growth inhibition by changing their distribution under UV-B and hydrogen peroxide exposure in ArabidopsisEffects of exogenous H2O2 application on Arabidopsis root growth. a The inhibitory effects of different concentrations of exogenous H2O2 on the growth of Arabidopsis seedlings at 7 DAG and 21 DAG and the recovery effects of DMTU on Arabidopsis seedlings at 16 DAG. b The root length results after different treatments. Scale bar = 10 mm (a). Different letters indicate significant differences (P < 0.05)Back to article page
