Phylogenetic analysis and expression of SbEXPA11. (a) Alignment of the amino acid sequences of EXPA11 of sorghum, barley, corn, rice, and wheat. Expansin-like EG45: expansin, family 45 endoglucanase-like domain; expansin-like CBD: expansin, cellulose-binding-like domain. Non-conservative amino acid sites are marked in red, and conservative regions are marked in blue. (b) Under control conditions (0 mM Cd), the expression level of SbEXPA11 in root and shoot. (c) Expression analysis of SbEXPA11 under different Cd concentrations. (d) Expression analysis of SbEXPA11 under 50 μM Cd at different times. Error bars are ±SE of n = 3. Significant differences analysis was carried out one-way ANOVA and Tukey’s post hoc test. Different letters above the column indicate significant differences (p < 0.05).
