Patent ID: 7795509

Claim:
A tobacco product comprising a transgenic plant cell from a transgenic tobacco plant of the genus Nicotiana having reduced quinolate phosphoribosyl transferase (QPRTase) production relative to a non-transformed control plant, said transgenic plant comprising transgenic plant cells comprising a heterologous nucleic acid; comprising a nucleotide sequence selected from the group consisting of: (a) the nucleotide sequence of SEQ ID NO:1; (b) a nucleotide sequence that encodes a quinolate phosphoribosyl transferase enzyme having the amino acid sequence of SEQ ID NO:2; (c) a nucleotide sequence that is at least 95% identical to the nucleotide sequence of (a) or (b) above and that encodes a quinolate phosphoribosyl transferase enzyme; and (d) a nucleotide sequence that differs from the nucleotide sequence of (a) or (b) above due to the degeneracy of the genetic code and that encodes a quinolate phosphoribosyl transferase enzyme.
