Fig. 3. JOXs and ST2A are involved in warm temperature-mediated plant growth.

a–d Representative images at 28 °C (a, c, e) and quantification of hypocotyl length (b, d, f) of 7-days-old Col-0 and a 35S::JOX1 line (a, b), jox-1-4 single and jox-Q quadruple mutant seedlings (c, d), and st2a-1 and st2a-2 (e, f) at 21 and 28 °C. Scale bar, 5 mm. Boxplots show mean as “+” and show median with Tukey-based whiskers and outliers, different letters denote significant differences (p < 0.05) based on two-way ANOVA with Tukey’s HSD with fold-change between 21 °C and 28 °C being presented (b, d, f). The number of individually measured seedlings (n) is indicated above the X axis (b, d, f). The exact p-value (or p < 0.0001) for the interaction (Genotype × Temperature) (b, d, f) is shown at the top.
