Movie of Growing Etiolated ein3-1;eil1-1(left) vs. Columbia-0 (right) Hypocotyls

Seedlings were treated with air (white background) for 1 hour followed by 7 hours of 10 mL L-1 ethylene (black background). This movie represents two experiments. To make growth comparisons easier to view, the individual frames for each time-point were digitally combined to make one video. The observation that the ein3;eil1 double mutant has a transient response to ethylene led to the hypothesis that there is a feedback loop in the ethylene signaling pathway (Binder et al., 2004, Prescott et al., 2016). We now are trying determine the nature of and components involved in this feedback. We also are searching for the components important for the transient ethylene response seen in the ein3;eil1 double mutants.
