Visser’s Claim 24
The homologous construct . . . [comprising a full
length potato] . . . GBSS cDNA or genomic DNA in reverse
orientation.
Hofvander’s Claim 13
A potato plant whose genome comprises the antisense
construct . . . [for inhibiting expression of the potato
gene which codes for . . . GBSS . . . comprising:
. . . a promoter, and
. . . a fragment of a potato gene coding for
. . . GBSS inserted in the antisense direction . . .
selected from the group consisting of SEQ No. 1,
SEQ ID No. 2 and SEQ ID No. 3].
Visser’s Claim 1
A . . . potato plant which . . . has a genome
containing at least one gene construct containing a full
length . . . GBSS cDNA or genomic DNA sequence coding
for . . . [potato] GBSS in reverse orientation in an
expression cassette . . . , said gene construct giving
rise to tubers containing essentially amylose free starch;
wherein said expression cassette comprises in the 5'-3'
direction of transcription: an upstream promoter sequence,
a base sequence for transcription into mRNA . . . , wherein
the coding strand of said base sequence for transcription
comprises an inverted sequence of bases complementary
to a run of bases of . . . [potato] GBSS mRNA, wherein
the transcript of said base sequence for transcription
substantially inhibits the expression of . . . [potato]
GBSS.
Hofvander and Visser present claims directed to methods of
using antisense constructs defined by Hofvander’s Claim 7 and/or
Visser’s Claim 15 to transgenically modify the genome of potato
plant cells by genetic engineering (Hofvander’s Claim 7) so to
grow and regenerate potato plants with “suppress[ed] . . .
