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.
Amylose-type starch obtained from a potato by a process comprising introducing into the genome of a potato tissue a gene construct comprising a fragment of the potato gene comprising a transcription start and first exon of the gene coding for formation of branching enzyme (BE gene) inserted in the antisense direction, together with a tuber-specific promoter.
