Functional characterization of GmNTL4. (A) Expression pattern of GmNTL4 in response to Al availability and treatment time. Lowercase letters represent significantly different groups in same treatment time; (B) Al-regulated expression pattern of GmNTL4 in different root segments. Asterisks indicate significant differences between 0 µM and 50 µM Al treatment in same root segments (*: p < 0.05 and *** p: < 0.001); (C) Phenotype of transgenic Arabidopsis with GmNTL4 overexpressing in response to Al toxicity. Bar = 0.5 cm; (D–F) Effects of GmNTL4 overexpression on the root elongation of Arabidopsis after 24 h (D), 48 h (E), and 72 h (F) of Al treatment. Asterisks indicate significant differences between WT and OX lines (***: p < 0.001).
