Other claims from this paper (19)
- Observation VvNCED1 and VvGT expression rose rapidly at véraison and peaked at week nine.
- Observation VvCYP1 and VvβG1 expression peaked at week ten.
- Observation VvβG1 expression remained high until harvest.
- Observation VvACO1, VvETR2 and VvCTR1 expression peaked transiently before véraison.
- Observation VvEIN4 expression increased from véraison to one week before harvest.
- Observation These expression changes recurred after harvest.
- Intervention effect NiCl2 plus 1-MCP inhibited ethylene release before véraison.
- Intervention effect NiCl2 plus 1-MCP inhibited expression of ethylene-related genes.
- Intervention effect NiCl2 plus 1-MCP suppressed VvNCED1 transcription.
- Intervention effect NiCl2 plus 1-MCP suppressed ABA synthesis.
- Mechanism The authors infer the double block may inhibit ripening onset.
- Intervention effect ABA treatment relieved the double block and restored ripening.
- Intervention effect After harvest the double block did not suppress VvNCED1 transcription.
- Intervention effect After harvest the double block did not suppress ABA accumulation.
- Intervention effect After harvest the double block did not inhibit fruit senescence onset.
- Mechanism The authors conclude VvNCED1 transcription leads to ABA generation.
- Mechanism The authors suggest ethylene and ABA interplay may be needed to initiate ripening.
- Mechanism The authors suggest some ABA is stored as ABA-GE after ABA peaks.
- Mechanism The authors propose postharvest abiotic stress induces VvNCED1 and ABA accumulation, starting senescence.
