Description
Isomaltulose (also marketed as palatinose, 6-O-α-D-glucopyranosyl-D-fructose) is an isomer of sucrose. It can be synthesised by the sucrose isomerase gene palI from Erwinia rhapontici which converts sucrose mainly into its isomaltulose isomer.

Potato plants were modified to insert  a chimeric sucrose isomerase gene from Erwinia rhapontici under the control of a tuber-specific promoter. As a result of the genetic modification a change in the carbohydrate metabolism of the potato tubers is expected in such a way that isomaltulose is synthesised in the potato tubers while the sucrose concentration is decreased.
Recipient Organism or Parental Organisms
The term Recipient organism refers to an organism (either already modified or non-modified) that was subjected to genetic modification, whereas Parental organisms refers to those that were involved in cross breeding or cell fusion.

Further details
Notes regarding the genetic elements introduced or modified in this LMO
The transit peptide of the proteinase inhibitor II from Solanum tuberosum is fused to the N-terminus of the palI gene. The signal peptide of the proteinase inhibitor II  governs secretion of the enzyme into the apoplasmic space.
