The Role of Epidermis in Wound Ethylene Production by Fruit Pericarp Tissue of Rin Mutant Tomato (Lycopersicon esculentum Mill.)

Abstract

Wound-induced ethylene production by fruit pericarp tissue of rin mutant tomato was studied in relation to role of the epidermis. Disks with intact epidermis produced more wound ethylene than disks without epidermis. Disks with intact epidermis were stimulated to produce more ethylene than disks without epidermis in response to 1 - aminocycopropane - 1 - carboxylic acid (ACC) application. This suggests that the compact cells close to the epidermis may at least be the location of enzyme(s) or other cofactor(s) required for the conversion of ACC to ethylene
