SiBRI1-OX was hypersensitive to BL in foxtail millet. (A), Phenotypes of Ci846 plants overexpressing SiBRI1 that were grown in the presence of the indicated concentration of BL for 6 days under 16L/8D 28 °C. Bar = 1 cm. (B), Relative root lengths of the plants in (A). N > 12. Error bars indicate the mean ± standard deviation (SD). Statistically significant differences are indicated by different lowercase letters (p < 0.05, two-way ANOVA with Tukey’s significant difference test). (C), The lateral root numbers of seedlings in (A). N > 12. Lateral roots with lengths greater than 1 mm are marked as elongated (E), those with lengths less than 2 mm are marked as unelongated (NE)
