Enhancement of Wound-Induced Ethylene Synthesis by Ethylene in Preclimacteric Cantaloupe 1

PMCID: PMC426201  PMID: 16662200

Abstract

Although intact fruits of unripe cantaloupe (Cucumis melo L.) produce very little ethylene, a massive increase in ethylene production occurred in response to excision. The evidence indicates that this wound ethylene is produced from methionine via 1-aminocyclopropanecarboxylic acid (ACC) as in ripening fruits. Excision induced an increase in both ACC synthase and the enzyme converting ACC to ethylene. Ethylene further increased the activity of the enzyme system converting ACC to ethylene. The induction by ethylene required a minimum exposure of 1 hour; longer exposure had increasingly larger effect. The response was saturated at approximately 3 microliters per liter ethylene and was inhibited by Ag+. Neither ethylene nor ACC had a promotive or inhibitory effect on ACC synthase beyond the effect attributable to wounding.
