  • Finishing agent
    Patent number: 5994532
    Abstract: The use of amylopectin-type starch obtained from potato that has been subjected to a genetical engineering modification to suppress the formation of amylose-type starch, as a finishing agent in papermaking is described.
    Type: Grant
    Filed: February 24, 1997
    Date of Patent: November 30, 1999
    Assignee: Sveriges Starkelseproducenter, Forening Upa
    Inventor: Olle Wikstrom
  • Genetically engineered modification of potato to form amylose-type starch
    Patent number: 5856467
    Abstract: Genetically engineered modification of potato for suppressing formation of amylopectin-type starch is described.The invention describes an antisense construct for inhibiting, to a varying extent, the expression of the gene coding for formation of branching enzyme (BE gene) in potato, said antisense construct comprising a tuber-specific promoter, transcription start and the first exon of the BE gene, inserted in the antisense direction.Also cells, plants, tubers, microtubers and seeds of potato comprising said antisense construct are described.Finally, amylose-type starch, both native and derivatized, derived from the potato that is modified in a genetically engineered manner, as well as a method of suppressing amylopectin formation in potato are described.
    Type: Grant

  • Genetically engineered modification of potato to obtain amylopectin-type starch
    Patent number: 5824798
    Abstract: Genetically engineered modification of potato for suppressing formation of amylose-type starch is described.Three fragments for insertion in the antisense direction into the potato genome are also described. Moreover, antisense constructs, genes and vectors comprising said antisense fragments are described. Further a promoter for the gene coding for formation of granule-bound starch synthase and also the gene itself are described.Also cells, plants, tubers, microtubers and seeds of potato comprising said antisense construct are described.Finally, amylopectin-type starch, both native and derivatized, derived from the potato that is modified in a genetically engineered manner, as well as a method of suppressing amylose formation in potato are described.
