Other claims from this paper (10)
- Observation Glucose 1-phosphate conversion to starch was exceptionally efficient.
- Intervention effect Unlabelled sucrose enhanced labelled glucose 1-phosphate incorporation into starch in fresh tuber slices.
- Intervention effect Unlabelled glucose 1-phosphate enhanced labelled sucrose incorporation into starch in fresh tuber slices.
- Intervention effect Storage abolished mutual enhancement of starch incorporation.
- Observation The glucose 1-phosphate path remained functional at lower temperatures and peaked near 20 °C.
- Observation Sucrose route flux rose strongly above 20 °C.
- Observation Mutants lacking plastidial phosphorylase had a largely impeded glucose 1-phosphate path.
- Observation Glucose 1-phosphate incorporation per granule surface area was equal regardless of granule size.
- Observation Recombinant plastidial phosphorylase mediated in vitro starch incorporation differed from in situ results.
- Mechanism Two interacting starch biosynthesis paths function in potato tuber cells.
