Other claims from this paper (16)
- Association Lines with increased NF-YA2 levels show the opposite phenotype to miR169d-overexpressing lines.
- Association Auxin levels are increased in MIR169d-OE and nf-ya2 mutant lines.
- Association ARGOS is upregulated in MIR169d-OE lines due to reduced NF-YA2 repressor levels.
- Observation NF-YA2 directly binds the ARGOS promoter.
- Association Overexpressing miR169d in an argos mutant background does not rescue the argos mutant phenotype, and nf-ya2:argos double mutants do not either.
- Mechanism The data suggest a parallel, auxin-independent pathway of ARGOS regulation via the MIR169:NF-YA2 node.
- Intervention effect Sly-MIR169-OE tomato lines flower early.
- Intervention effect Sly-MIR169-OE tomato lines fruit early.
- Intervention effect Sly-MIR169-OE tomato lines have more fruit fresh weight than wild-type plants.
- Intervention effect Sly-MIR169-OE tomato lines produce larger sized fruits than wild-type plants.
- Intervention effect Sly-MIR169-OE tomato lines have higher fruit set than wild-type plants.
- Intervention effect Sly-MIR169-OE tomato lines have better shelf life than wild-type plants.
- Association Sly-STTM169 tomato plants with increased Sly-NF-YA10 have a longer life cycle.
- Association Sly-STTM169 tomato plants have reduced biomass.
- Association Sly-STTM169 tomato plants have decreased fruit set.
- Association Sly-STTM169 tomato plants show an overall reduction in yield.
