Effect of Rhizobitoxine, Cycloleucine and Cycloheximide on Wound Ethylene Production by Fruit Pericarp Tissue of Rin Mutant Tomato.

Abstract

Both l-aminocyclopropane-l-carbosylicc acid (ACC) and S-adenosylmethionine (SAM) increased wound ethylene production by fruit pericarp tissue to rin mutant tomato but ACC was more effective than SAM. Rhizobitoxine or cycloleucing given along with ACC stimulated more wound ethylene production. Rhizobitoxine inhibited SAM-stimulated wound ethylene production but cycloleucine did not. This suggests that cycloleucine may have different mode of action from rhizobitoxine. Cyeloheximide inhibited wound ethylene production by tomato disks treated and non-treated with ACC.
