Phenotypes observed in DDA1-EAR seedlings. (A) Reduction in root growth resulting from 2,4-D exposure. Seedlings were grown as described in Fig. 3. On the third day, ethanol induction was initiated and maintained for 4 d. The percentage growth inhibition was calculated from growth on 2,4-D relative to growth on unsupplemented medium. A minimum of 10 seedlings was assayed for each condition. Error bars represent the standard error. t-test P <0.001 (no ethanol×with ethanol). (B) Hypocotyl length of 7-day-old seedlings grown under a 16 h light/8 h dark photoperiod. A minimum of 12 seedlings was assayed for each condition. Error bars represent the standard error. t-test P <0.000001 (no ethanol×with ethanol).
