Fig. 2From: Actin filaments mediated root growth inhibition by changing their distribution under UV-B and hydrogen peroxide exposure in ArabidopsisUV-B inhibited hypocotyl elongation and root growth in Arabidopsis seedlings. a–d UV-B inhibited the hypocotyl elongation of 5 DAG seedlings of Lifeact-Venus and uvr8. e–h H2O2 content in the roots after H2DCF staining. i–l The distribution of actin filaments in the Arabidopsis hypocotyl before and after UV-B treatment in Lifeact-Venus and uvr8. m The effects of UV-B on Arabidopsis root length. n Statistics on the mean fluorescence intensity of H2DCF staining in roots from each group. o The effects of UV-B treatment on hypocotyl elongation. p Statistics on skewness in hypocotyls of each group. Scale bar = 5 mm (a–d); 10 mm (e–h); 30 μm (i–l). Different letters indicate significant differences (P < 0.05).Back to article page
