Other claims from this paper (10)
- Observation A seedless JA biosynthesis mutant, Sldad1, was identified.
- Association JA levels correlated with SlDAD1 transcript abundance.
- Observation JA accumulated in ovary and ovule before anthesis.
- Observation Sldad1 produced seedless fruit without manual pollination or emasculation.
- Observation Sldad1 produced seeded fruit through self-pollination.
- Observation The mutant had increased cell expansion.
- Observation The mutant had elevated GA levels.
- Observation The mutant had higher SlGA20ox3 transcript levels.
- Intervention effect GA biosynthesis inhibition suppressed Sldad1 fruit set.
- Mechanism The authors propose that filament-derived JA accumulates in ovules and prevents fruit set partly via GA metabolism.
