Granule-bound starch synthase (GBSS) is transformed in an antisense orientation into potato leading to a decrease in the synthesis of endogenous GBSS. Due to the decreased amount of GBSS protein, a starch with reduced amylose content is synthesised in the tubers.
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
Characteristics of the transformation process
pAP2 (pPZP200 derivative)
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.
Acetohydroxy acid synthase gene - Arabidopsis thaliana - Thale cress, Mouse-ear cress, Arabidopsis, ARATH
Resistance to herbicides - Imidazolinone, Sulfonylurea
Granule-bound starch synthase gene - Solanum tuberosum - Potato, SOLTU
altered carbohydrate composition: increased amylopectin content
Nopaline Synthase Gene Promoter - Agrobacterium tumefaciens - Agrobacterium
Nopaline Synthase Gene Terminator - Agrobacterium tumefaciens - Agrobacterium
Granule bound starch synthase gene promoter - Solanum tuberosum - Potato, SOLTU
Notes regarding the genetic elements introduced or modified in this LMO
Notes about the Transcriptional regulator(s) specific to this LMO

The fragment of the coding region of a potato starch synthase gene (granule-bound starch synthase, GBSS) in antisense orientation (plasmid pAP2) is expressed under the control of its own gbss promoter primarily in the potato tuber.

In the genetically modified plants, the formation of a double-stranded RNA is effected, which causes inactivation of the endogenous transcript of the respective gene, thus inhibiting production of the GBSS enzyme.
