Abstract
Ethylene is well thought-out stress hormone because its synthesis is induced by a variety of stresses. 1-Aminocyclopropane-1-carboxylate (ACC) is the immediate precursor of ethylene in higher plants. Some rhizobacteria can hydrolyze ACC into ammonia and α-ketobutyrate because of their ACC-deaminase activity. This study was conducted to investigate the influence of ACC-deaminase rhizobacteria on the ACC-induced classical “triple” response in etiolated pea seedlings. Etiolated pea seedlings were exposed to different concentrations of ACC (0
