Other claims from this paper (9)
- Intervention effect Exposure of mature, presenescent carnation flowers to 7.5 microliters per liter ethylene for at least 6 hours induced petal in-rolling and premature senescence.
- Intervention effect Autocatalytic ethylene production was induced in carnation petals by ethylene treatment for 12 or more hours.
- Intervention effect At least 6 mRNAs accumulated in carnation petals following ethylene exposure.
- Observation Carnation petal in vitro translation products had molecular weights of 81, 58, 42, 38, 35 and 25 kilodaltons.
- Intervention effect Significant increases in abundance of most mRNAs were observed 3 hours after ethylene exposure.
- Intervention effect Ethylene exposure decreased abundance of another group of carnation petal mRNAs.
- Intervention effect Competitive inhibitors of ethylene action largely prevented induction of ethylene responses in carnation petals.
- Association An increase in flower age was accompanied by an increase in the capacity of ethylene to induce petal in-rolling, autocatalytic ethylene production and changes in mRNA populations.
- Mechanism Ethylene responses in carnation petals are suggested to be regulated by both sensitivity to ethylene and ethylene concentration.
