Tzyy-Jen Chiou; Daniel R. Bush Proceedings of the National Academy of Sciences 1998. doi:10.1073/pnas.95.8.4784

Other claims from this paper (12)

Intervention effect Feeding leaves 100 mM sucrose lowered symporter activity to 35-50% of water controls.
Intervention effect Feeding leaves 250 mM sucrose lowered symporter activity to 20-25% of controls.
Intervention effect Alanine symporter activity did not change with sucrose treatment.
Intervention effect Glucose transporter activity did not change with sucrose treatment.
Observation Decreased sucrose symporter activity was detectable after 8 h.
Observation The sucrose symporter activity decline reached a maximum by 24 h.
Observation Symporter message levels decreased.
Observation Changing osmotic conditions did not account for the sucrose responses.
Intervention effect Equal molar concentrations of hexoses did not elicit the sucrose response.
Intervention effect Mannoheptulose did not block the sucrose effect.
Observation Sucrose-dependent symporter changes were reversible.
Mechanism Sucrose acts as a signal in a pathway regulating the symporter and assimilate partitioning.
