The effect of Aminooxyacetic acid on ethylene production induced by methyl jasmonate in tomatoes

Aminooxyacetic acid (AOA), an inhibitor of ACC biosynthesis, applied together with methyl jasmonate (JA-Me) to mature green and light-green tomatoes cv. Venture greatly inhibited ethylene production stimulated by JA-Me, when analyzed in ripe and overripe stages. AOA applied alone did not affect ethylene production in the same conditions of treatment and analysis. It is suggested that after JA-Me treatment of tomatoes the turnover rate of ACC is higher (JA-Me stimulates EFE activity) in comparison to control tissues, and, consequently, AOA inhibited ethylene production stimulated by methyl jasmonate.
