SLAH3 is required for SnRK1.1 to regulate hypocotyl growth in dark. A, The phenotypes of Col-0, slah3-4, SnRK1.1-OE lines cultivated for 8 d under different culture conditions in dark. White scale = 2 cm. B, The phenotypes of Col-0, slah3-4, and mSnRK1.1-OE lines cultivated for seven days under different culture conditions in the dark. White scale = 2 cm. C and D, The statistical analyses of hypocotyl length on the plants presented in (A) and (B). Data are shown as means ± se, n = 20. Statistical analyses were performed by two-way ANOVA analysis with Tukey’s multiple comparisons test. Significant differences are indicated with different letters. P <0.05. S, Sucrose.
