Abstract
A potato plant which has a genome containing, as a result of genetic engineering, at least one gene construct containing a potato granule-bound starch synthase (PGBSS) cDNA or genomic DNA sequence in reverse or functional orientation in an expression cassette which is functional in potato plants, the gene construct giving rise to tubers containing essentially amylose-free starch. In one embodiment, the gene construct contains a PGBSS cDNA sequence in reverse orientation which results in the production of PGBSS antisense RNA.
