Fig. 4 — The hypocotyl growth rate in response to ethylene was recorded for 1 h in air, followed by 2 h exposure to 10 ppm ethylene and then 5 h recovery in air. Ethylene was introduced 1 h after measurements were initiated (down arrow) and then removed 2 h later (up arrow). The responses of wild-type seedlings are shown in each graph. a 35S:GFP-ΔNT-CTR1 and 35:GFP-ΔNT-CTR1^ctr1-1. b 35S:GFP-CTR1 and 35:GFP-CTR1^ctr1-1. c ctr1-8, CTR1p:GFP-gCTR1^ctr1-8-SV40/ctr1-8, and CTR1p:GFP-gCTR1/ctr1-8. Data were normalized to the growth rate in air before treatment with ethylene. The experiments were repeated at least twice and generated similar results. The graphs indicate the quantification of time to reach pre-treatment growth rate after ethylene removal. Error bars, SE, Two-tailed Student’s t test.
