Precursors of Ethylene [PDF]

Plant Physiology, 1969
Two pathways for biosynthesis of ethylene in higher plants have been postulated (10). One is associated with the breakdown of peroxidized linolenic acid and the other involves the degradation of methionine. Although the formation of ethyilene from peroxidized linolenate has been demonstrated in model systems catalyzed by Cu24, oxygen and ascorbic acid (
