- Association Endogenous sucrose levels strongly correlated with AGPase redox activation.
- Intervention effect Sugar-free incubation decreased AGPase redox activation in wild-type potato tuber discs.
- Intervention effect Glucose supply prevented the decrease in AGPase redox activation.
- Intervention effect Sucrose supply prevented the decrease in AGPase redox activation.
- Intervention effect EDTA preparation increased sucrose uptake and AGPase redox activation.
- Intervention effect EDTA preparation had no effect on glucose uptake.
- Mechanism Hexokinase phosphorylation of hexoses was essential for glucose-dependent AGPase activation.
- Intervention effect Palatinose activated AGPase similarly to sucrose.
- Intervention effect Sucrose feeding prevented AGPase inactivation in wild-type but not SnRK1 antisense tuber discs.
- Intervention effect Glucose feeding activated AGPase similarly in wild type and SnRK1 transformants.
- Intervention effect Invertase overexpression increased AGPase redox activation in transgenic tubers.
- Intervention effect Bacterial glucokinase expression in the invertase background decreased AGPase activation.
