• 23. Characterization of novel chemical with ethylene mimic activity

抄録

The gaseous hormone ethylene plays important roles in many physiological and developmental processes in plants. To regulate ethylene signaling, we screened novel chemicals with ethylene mimic activity that induce triple response phenotype of etiolated seedlings. Finally we identified a compound with ethylene mimic activity, named HJ2. Ethylene biosynthetic inhibitor did not suppress HJ2-induced phenotype. On the other hand, ethylene insensitive mutant, ein2, suppressed HJ2-induced phenotype. Moreover, antagonist of ethylene receptor, STS, suppressed HJ2-induced phenotype in dose-dependent manner. These results suggested that HJ2 is an agonist of ethylene receptor. To improve ethylene activity of HJ2, we designed and synthesized HJ2 derivatives. As a result, we developed more effective ethylene agonists. At present, we examine binding of these chemicals to ETR1 protein in detail.
