Other claims from this paper (14)
- Observation Earl's Favourite retained low ethylene biosynthetic activity through commercial harvest maturity.
- Observation Earl's Favourite intact fruit had low ethylene production.
- Observation Andes mesocarp and placenta ACC content rose sharply at commercial harvest maturity.
- Observation Andes intact fruit ethylene production rose sharply at commercial harvest maturity.
- Observation CMe-ACS1 mRNA accumulated in Andes mesocarp and placenta at commercial maturity.
- Observation CMe-ACS1 mRNA did not accumulate in Earl's Favourite tissues at any maturity.
- Observation ACO1 mRNA accumulated in both cultivars at commercial maturity.
- Observation ACO2 was almost constitutively expressed.
- Observation Applied ethylene slightly induced CMe-ACS1 mRNA in Andes fruit.
- Observation Applied ethylene did not induce CMe-ACS1 mRNA in Earl's Favourite.
- Observation Wounding induced CMe-ACS1 transcripts in both cultivars.
- Observation Ethylene and wounding stimulated ACO1 mRNA accumulation in both cultivars.
- Observation MCP treatment made CMe-ACS1, ACO1 and ACO2 transcripts barely detectable in climacteric Andes fruit.
- Mechanism The authors attribute cultivar ethylene differences to CMe-ACS1 expression during ripening and ethylene response.
