Other claims from this paper (12)
- Observation Inhibition of Susy activity in the antisense plants was tuber-specific.
- Intervention effect Susy inhibition caused no change in sucrose content in developing potato tubers.
- Intervention effect Susy inhibition caused a strong accumulation of reducing sugars in developing potato tubers.
- Intervention effect Susy inhibition inhibited starch accumulation in developing potato tubers.
- Observation Invertase activities increased 40-fold in parallel with the increase in hexoses.
- Observation Hexokinase activities showed no considerable changes.
- Observation Total tuber dry weight decreased.
- Observation Soluble tuber proteins were reduced.
- Observation The reduced protein accumulation was mainly due to a decrease in patatin, the 22 kDa proteins and the proteinase inhibitors.
- Observation The lowered storage protein accumulation was not a consequence of the availability of the free amino acid pool in potato tubers.
- Intervention effect Susy antisense plants showed no increase in tuber number per plant.
- Mechanism The authors conclude that sucrose synthase is the major determinant of potato tuber sink strength.
