Gene Introduced Gene Source Product Function
NtQPT1 (antisense) Nicotiana tabacum  antisense RNA of quinolinic acid phosphoribosyltransferase (QPTase) gene; no functional QPTase enzyme is produced suppresses the transcription of the QPTase gene, thereby reducing the production of nicotinic acid, a precursor for nicotine
nptII  * Escherichia coli Tn5 transposon neomycin phosphotransferase II enzyme allows transformed plants to metabolize neomycin and kanamycin antibiotics during selection
