Abstract
The present disclosure provides the identification of tobacco Nic1 locus. Also provided are tobacco plants with altered total alkaloid and nicotine levels and commercially acceptable leaf grade, their development via breeding or transgenic approaches, and production of tobacco products from these tobacco plants. Also provided are compositions and methods for producing tobacco plants having novel Nic1 mutations or alleles to reduce nicotine levels. Further provided are sequence polymorphisms and molecular markers for breeding tobacco with reduced nicotine or nicotine free while maintaining tobacco leaf grade and tobacco product quality.
