transcription into mRNA under control of said upstream
promoter base sequence comprising coding and template
strands, and a downstream transcription terminator base
sequence, wherein the coding strand of said base sequence
for transcription comprises an inverted sequence of bases
complementary to a run of bases of PGBSS mRNA, wherein
the transcript of said base sequence for transcription
substantially inhibits the expression of PGBSS.

wherein said upstream promoter sequence is the cauliflower
mosaic virus 35S promoter (PCaMV).
5. The transgenic potato plant according to claim 1
wherein said upstream promoter sequence is the PGBSS
promoter.
6. The transgenic potato plant according to claim 1
wherein said terminator is nopaline synthase terminator
(Tnos).
7. The transgenic potato plant according to claim 1
wherein said terminator is PGBSS terminator.
8. The potato plant of claim 1, wherein the gene
construct contains the neomycin phosphotransferase II gene
(NPT-II) kanamycin resistance marker.
11. A tuber of the potato plant of claim 1.
13. The transgenic potato plant of claim 1 wherein said
construct contains full length PGBSS cDNA.
14. The transgenic potato plant of claim 1 wherein said
base sequence for transcription comprises a sequence of
bases complementary to the sequence as set forth in
Figure 3.
