    摘要： The present invention generally relates to methods and materials involved in producing tobacco plants having reduced levels of conversion of nicotine to nornicotine. In certain embodiments, the invention is directed to mutations in a nicotine demethylase gene, tobacco plants comprising mutations in a nicotine demethylase gene, and tobacco compositions and products thereof. In other embodiments, the invention is directed toward nicotine demethylase RNA interference, tobacco plants comprising a nicotine demethylase RNA interference transgene, and tobacco compositions and products thereof.
