Triple response of Arabidopsis wild-type Col-0 and ethylene biosynthesis octuple mutant acs8x with and without AIB treatment. Arabidopsis wild-type Col-0 and ethylene biosynthesis octuple mutant acs8x were sown with or without AIB treatment (2 mM). (A) Pictures of representative 4-day-old etiolated Col-0 and acs8x seedlings. (B) Hypocotyl length and (C) root length of Col-0 and acs8x seedlings (13 ≤ n ≤ 26; 3 independent replicates). (D) Relative hypocotyl length and (E) relative root length of acs8x seedlings. In panels (D) and (E), lengths are expressed relative to the corresponding genotype on medium without AIB. In panels (B) and (C), different letters indicate statistically significant differences between the different groups (Kruskal-Wallis, Dunn’s Multiple Comparison Test, P < 0.01). T-tests were carried out in panels (D) and (E) to compare differences within a genotype (P < 0.01 is indicated with *; P < 0.0001 is indicated with ***). Error bars are SD. Effect sizes are presented in Table S1 .
