Fragments of the coding region of the potato gbss gene in sense and antisense orientation (inverted repeats) were introduced into potato. The formation of a double-stranded RNA causes inactivation of the  transcript of the endogenous gbss gene, thus preventing production of the GBSS enzyme. The decreased amount of GBSS protein leads to a reduction of the amylose fraction in the starch of the potato tuber and in a concomitant increase in the levels of amylopectin.
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.
Solanum tuberosum - Potato, SOLTU
Point of collection or acquisition of the recipient organism
Potato cultivar/breeding line P800
Characteristics of the transformation process
Derivate of pPZP200
Techniques used for the modification
  • Agrobacterium-mediated DNA transfer
Introduced or modified genetic elements
Some of these genetic elements may be present as fragments or truncated forms. Please see notes below, where applicable.
