The invention relates to a resistance gene and functional homologs or fragments thereof isolated fromor. Moreover, the invention relates to the use of said resistance gene, for example the use of said resistance gene in a method to increase or confer at least partial resistance in a plant to an oomycete infection. The invention provides an isolated or recombinant nucleic acid sequence comprising a nucleic acid sequence encoding one of the amino acid sequences of FIG.or a functional fragment or a functional homolog thereof such as those presented in FIG.

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.

Potato plant producing essentially amylose-free starch

Plasmids are described having DNA sequences that after insertion into the genome of the plants cause changes in the carbohydrate concentration and the carbohydrate composition in regenerated plants. These changes can be obtained from a sequence of a branching enzyme that is located on these plasmids. This branching enzyme alters the amylose/amylopectin ratio in starch of the plants, especially in commercially used plants.
