title: Involvement of sucrose synthase in sucrose synthesis during mobilization of fructans in dormant Jerusalem artichoke tubers.
abstract: The relative contribution of sucrose synthase and sucrose-phosphate synthase to sucrose synthesis in dormant tubers of Jerusalem artichokes was determined. Feeding dormant tubers alternatively with mixtures of [14C]glucose and unlabeled fructose, and [14C]glucose and [14C]fructose has shown that sucrose synthase contributes ca. 95-97% to sucrose synthesis. This is the first report of sucrose synthesis in Jerusalem artichokes dormant tubers.
