Patent ID: 7645925

Claim:
A tobacco product produced from a transgenic tobacco plant of the genus Nicoriana having increased quinolate phosphoribosyl transferase (QPRTase) production relative to a non-transformed control plant, said transgenic plant comprising transgenic plant cells comprising: an exogenous nucleic acid construct comprising, in the 5′ to 3′ direction, a promoter operable in said plant cell and a heterologous nucleic acid operably associated with said promoter; said plant exhibiting increased QPRTase production compared to a non-transformed control plant and; said 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 an enzyme having the amino acid sequence of SEQ ID NO:2; (c) a nucleotide sequence having at least 95% identity with the nucleotide sequence of (a) or (b) above and that encodes a plant quinolate phosphoribosyl transferase; 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 plant quinolate phosphoribosyl transferase enzyme.
