Other claims from this paper (7)
- Intervention effect Calcium treatment increased ACC/MACC content and ACC oxidase activity in tomato fruit discs.
- Intervention effect Calcium treatment decreased ethylene production in tomato fruit discs.
- Intervention effect Calcium treatment decreased malondialdehyde content and membrane permeability in tomato fruit discs.
- Intervention effect Calcium treatment did not affect ACC synthase activity in tomato fruit.
- Intervention effect Calcium treatment inhibited LeACO1 expression in mature green fruit of wild-type and Nr tomato, with a significant effect.
- Observation The effect of calcium on ethylene biosynthesis in tomato mature green fruit was independent of ethylene perception.
- Mechanism Calcium prevents ethylene production at the ACC-to-ethylene step by inhibiting ACC availability for ACO through enhanced membrane integrity and by preventing LeACO1 expression.
