Hypocotyl and root elongation of 35S:ARR1-SRDX transgenic seedlings in response to ethylene. A, Hypocotyl elongation of 35S:ARR1-SRDX transgenic seedlings on ACC-containing medium compared with the wild type. Transgenic seedlings show resistance at higher concentrations of ACC. Seedlings were placed on vertical MS medium plates containing 0.1, 1.0, 10, or 30 μm ACC. Hypocotyl lengths were measured after 4 d of dark incubation. B, Primary root elongation of 35S:ARR1-SRDX transgenic plants on ACC-containing medium. Root elongation was inhibited to a similar extent in both wild-type and transgenic seedlings. Seedlings were grown on medium containing 10 μm ACC for 4 d in the dark. More than 15 seedlings in two replicates were analyzed for each genotype. Error bars represent sd (n ≥ 15). Pairwise Student's t test was used to compare values with the wild type. *, 0.01 < P < 0.05; **, 0.001 < P < 0.01. ARR1-S-8 and ARR1-S-10 are two independent lines of 35S:ARR1-SRDX transgenic plants.
