Abstract
Changes in soluble lipoxygenase (EC 1.13.11.12) activity related to endogenous and exogenous ethylene production and wounding were studied in the growing primary leaves of light-grown rye (Secale cereale L.) seedlings. Maximum lipoxygenase activity was localized in the most juvenile, rapidly growing leaf tissues of rye seedlings and coincided with a high rate of ethylene production. Treatment of rye seedlings with 10 mM ethephon or 50 mM 1-aminocyclopropane-1-carboxylic acid (ACC) resulted in activation of lipoxygenase. Detachment of leaves also induced an increase of lipoxygenase activity.
