Interference 103,579
obtaining a potato tissue which has been transformed by
introducing into the genome of the potato tissue a gene
construct comprising a promoter and a fragment of the
potato gene which codes for the information of granule-
bound starch synthase inserted in the anti-sense
direction, wherein said fragment essentially has a
nucleotide sequence which is selected from the group
consisting of SEQ ID No. 1, SEQ ID No. 2 and SEQ ID
No. 3;
growing the transformed potato tissue to produce a potato
plant containing potato tubers;
producing at least one potato from said potato tubers; and
separating starch from said potato, wherein said starch
is an amylopectin-type starch which is essentially free
of amylose.
(2) The process for producing an amylopectin-type
starch according to claim 1, wherein said fragment has a
nucleotide sequence of SEQ ID No. 1.
(3) The process for producing an amylopectin-type
starch according to claim 1, wherein said fragment has a
nucleotide sequence of SEQ ID No. 2.
(4) The process for producing an amylopectin-type
starch according to claim 1, wherein said fragment has a
nucleotide sequence of SEQ ID No. 3.
(5) The process for producing an amylopectin-type
starch according to claim 1, wherein said promoter
comprises a CAMV 35S promoter.
(6) The process for producing an amylopectin-type
starch according to claim 1, wherein said promoter
comprises a patatin I promoter.
(7) The process for producing an amylopectin-type
starch according to claim 1, wherein said promoter
comprises a GBSS promoter.
(8) The process for producing an amylopectin-type
starch according to claim 7, wherein said GBSS promoter
has the nucleotide sequence of SEQ ID No. 4.
