Ethylene-dependent constitutive cytokinin responses in 35S:ARR1D94E (PM- ox ) seedlings. (A) Representative seven-day-old Col-0, ein2-1, PM-ox (H) and PM-ox (H) ein2-1 plants grown on vertical MS/2 plates. (B) Root length of seven-day-old seedlings was measured from photographs. Data are presented as mean ± SD (n = 20). One-way ANOVA with Tukey's multiple comparison test was used to analyze the statistical significance of the results. Only the significance of the difference between Col-0 and PM-ox (H) ein2-1 is shown. ****, P < 0.0001. (C) Representative four-day-old seedlings germinated and grown in darkness on MS/2 medium. (D) Hypocotyl length of four-day-old etiolated seedlings. Data are presented as mean ± SD (n = 20). Only the significance of the difference between Col-0 and PM-ox (H) ein2-1 is shown. ns, not significant (one-way ANOVA with Tukey's multiple comparison test).
