LMO name
Potato modified for altered starch composition
Transformation event
Multiple events
Developer(s)
Description
The LMOs contain one of two constructs that are made up of an antisense cassette to inhibit expression of the endogenous granule bound starch synthase (GBSS)gene in potato. The constructs do not contain selection markers. 
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
Vector
pKGBA50mf-IR1.1 or pIRMASmf

Further details
Notes regarding the genetic elements introduced or modified in this LMO
Additional information on the inserted DNA sequences
pKGBA50mf-IR1.1 contains between the borders: GBSS promoter: Tuber specific and sugar inducible promoter of the GBSS gene from Solanum tuberosum; 1.1 kb of sense DNA sequences of the GBSS gene from Solanum tuberosum encoding the N-terminus of the GBSS protein; AS-GBSS: anti-sense strand of the GBSS gene from Solanum tuberosum; and the NOS terminator.

pIRMASmf contains between the borders: GBSS promoter: Tuber specific and sugar inducible promoter of the GBSS gene from Solanum tuberosum; M-GBSSI (antisense): 617 bp (bps. 1070-1687) of antisense strand of GBSS cDNA from Solanum tuberosum; M-GBSSI (sense): 761 bp (bps. 926-1687) of GBSS-cDNA from Solanum tuberosum; and the NOS terminator.
