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.
