Abstract The catecholamines (50 μM dopamine, 50 μM norepinephrine and 100 μM epinephrine) and phenylethylamine (200 μM) were found to stimulate ethylene production in potato suspension cultures. When 100 μM amino-oxyacetic acid was added together with epinephrine, ethylene release returned to control levels. The endogenous 1-aminocyclopropane-1-carboxylic acid levels were increased in parallel with the release of ethylene, suggesting that the observed effect probably occurs via regulation of aCC synthase. Our results suggest that there is a link between these naturally occurring monoamines and ethylene in plants.
