| Abstract: | Nornicotine,which is produced by N-demethylation of nicotine,can serve as the precursor of potential carcinogen N-nitrosonornicotine(NNN) synthesis.Nicotine N-demethylase(NND) genes were cloned and applied to evolutionary analysis.These genes were also employed as target for tobacco breeding to produce tobacco with low level of nornicotine.In this review,the recent works concentrated on NND genes and suggestions for future research were discussed. |
