Growth response kinetics of dark-grown Arabidopsis seedling hypocotyls. (A) The normalized growth rate of wildtype Arabidopsis. Seedlings were grown in air for 1 h at which time 10 ppm ethylene was applied for 2 h at which time ethylene-free air was used to replace the ethylene. (B) The normalized growth rate of wildtype Arabidopsis compared to ein3;eil1 and ein2 mutants. Seedlings were grown in air for 1 h at which time 10 ppm ethylene was applied. (C) The normalized growth rate of wildtype Arabidopsis treated with varying concentrations of ethylene as indicated. Seedlings were grown in air for 1 h prior to application of ethylene. In all panels, the growth rate was normalized to the growth rate in air prior to treatment with ethylene. Based on data from Binder et al. (2004a,b).
