Root tip staining phenotypes of hairy roots. a Expression levels of GsERF1 in control, OX-GsERF1 and RNAi-GsERF1 hairy roots. b The control, OX-GsERF1 and RNAi-GsERF1 hairy roots were stained with hematoxylin after Al treatment. The control, OX-GsERF1 and RNAi-GsERF1 hairy roots were subjected to 50 μM AlCl3 (0.5 mM CaCl2, pH 4.5) for 12 h. OX: GsERF1-overexpressing plants; RNAi: GsERF1-silenced plants. The data are the mean values ± SDs, and all the experiments included three biological replications
