Other claims from this paper (10)
- Intervention effect High sucrose delayed flowering and increased leaf number at flowering.
- Mechanism The high-sucrose effect appeared metabolic rather than osmotic.
- Mechanism The flowering delay came from extension of the late vegetative phase.
- Association Extended late vegetative phase delayed LFY expression.
- Intervention effect Low sucrose slightly inhibited flowering in wild-type plants.
- Mechanism Low-sucrose flowering delay resulted from early vegetative phase effects.
- Association Low-sucrose inhibition was more pronounced in tfl1 than wild type.
- Intervention effect Further sucrose increase delayed floral transition of co, fca and gi mutants.
- Intervention effect One-percent sucrose did not restore reduced FT and SOC1/AGL20 expression in co or fca.
- Intervention effect One-percent sucrose repressed FT and SOC1/AGL20 expression in wild type.
