Other claims from this paper (10)
- Intervention effect Exogenous sucrose application promoted flowering in rice.
- Intervention effect Exogenous sucrose application induced florigen gene expression in rice.
- Intervention effect Overexpression of the vacuolar invertase OsVIN2, which reduces phloem sucrose, delayed flowering in rice.
- Intervention effect Mutation of the sucrose transporter OsSUT2, which reduces phloem sucrose, delayed flowering in rice.
- Intervention effect Sucrose activated Ehd1 upstream of the florigen in rice.
- Intervention effect Sucrose had no significant effect on the expression of other upstream floral regulatory genes in rice.
- Observation The Ghd7 protein interacted with the E3 ligase IPA INTERACTING PROTEIN1 (IPI1).
- Intervention effect Sucrose induced polyubiquitination of Ghd7 via IPI1, leading to Ghd7 protein degradation.
- Intervention effect Mutants defective in IPI1 delayed flowering in rice.
- Mechanism Sucrose is concluded to act as a signaling molecule that induces flowering in rice by promoting Ghd7 degradation via IPI1.
