Biosynthesis of Stress Ethylene in Soybean Seedlings: Similarities to Endogenous Ethylene Biosynthesis

摘要

The similarity of stress ethylene biosynthesis in whole plants to endogenous ethylene biosynthesis was investigated using two inhibitors of ethylene biosynthesis, amino-ethoxyvinylglycine (AVG) and cobalt chloride (Co2+); and the intermediates, methionine, S-adenosylmethionine (SAM), and 1-aminocyclopropane-1-carboxylic acid (ACC), of basal ethylene biosynthesis. The results suggest a common pathway in whole plants for stress ethylene production and endogenous ethylene biosynthesis.
