Tolerant phenotype to Al stress of GsMYB7 transgenic lines. A, B The phenotypes were observed after 5 days of treatment with CaCl₂ solution containing different concentrations of AlCl₃. The seedlings were treated with 0, 25 μM AlCl₃, respectively. C, D The scanned roots were observed after AlCl₃ treatment with concentrations of 0 and 25 μM, respectively. E The total root area of L1, L2 and WT under 0 and 25 μM AlCl₃ treatments for 5 days. F The total Al accumulations in L1, L2 and WT were determined via ICP-AES analysis. The asterisk indicated that there was significant difference between HC6 and GsMYB7 transgenic lines (*P < 0.05; **P < 0.01). WT: wild type, Huachun 6; L1, L2: GsMYB7 transgenic soybean of T₃ generation
