RNAi profiling of Arabidopsis Col-0 plants (air control), 8 week old Col-0 plants treated for 24 hours with ethylene gas (10 ppm), and artificial microRNA knockdown mutants, amiR-ETP1/2 - interplay between ethylene, ETP1/ETP2 F-box proteins, and degradation of EIN2 triggers ethylene responses in Arabidopsis

ABSTRACT: A complex interplay between ethylene, ETP1/ETP2 F-box proteins, and degradation of EIN2 is essential for triggering ethylene responses in plants. The gaseous plant hormone ethylene can trigger myriad physiological and morphological responses in plants. While many ethylene signaling pathway components have been identified and characterized, little is known about the function of the integral membrane protein EIN2, a central regulator of all ethylene responses. Here, we demonstrate that Arabidopsis thaliana EIN2 is a protein with a short half-life that undergoes rapid proteasome-mediated protein turnover. Moreover, EIN2 protein accumulation is positively regulated by ethylene. We identified two F-box proteins, EIN2 TARGETING PROTEIN and 2 (ETP1 and ETP2), that interact with the EIN2 carboxyl-
