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 The reduction in starch accumulation was not due to inhibition of the major starch biosynthetic enzymes.
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.
