Abstract
Auxin-induced ethylene biosynthesis and its regulatory steps in etiolated mung bean hypocotyl segments were examined. The endogenous content of 1-aminocyclopropane- 1-carboxylic acid (ACC), an immediate precursor of ethylene, increased corresponding to the rate of ethylene production. Benzyladenine (BA), which is a synergistic stimulator of auxin-induced ethylene production, increased the ACC content parallel to the rate of ethylene production in the presence of IAA, but failed to increase the ACC content in the absence of IAA while ethylene production was significantly stimulated by BA. Abscisic acid (ABA) inhibited the formation of ACC. The ACC synthase activity in the tissue was increased by IAA, and the increase was further promoted by the presence of BA. Cycloheximide severely inhibited the development of auxin-induced ACC synthase. The enzymatic properties of mung bean ACC synthase were similar to those of the tomato fruit enzyme. Aminoethoxyvinylglycine (AVG) and aminooxyacetic acid, which inhibit the ACC synthase reaction, stimulated the development of ACC synthase. The regulatory mechanisms of the growth regulators are discussed in relation to ACC formation.
