Figure 5. Effect of iar4-5 mutation on the hypocotyl phenotype of fei1 fei2.

(A) Seedlings of the indicated genotypes were grown for four days in the dark on MS medium with 0% sucrose. Representative seedlings were imaged using dark field microscopy. (B) Quantification of hypocotyl widths from seedlings grown as in (A). Values represent the mean (n = 20) ± SE. Different letters indicate significant differences between groups. Data were analyzed with one-way ANOVA and Tukey's post-hoc comparisons; P<0.05.
