FIELD: biochemistry. SUBSTANCE: invention relates to a mutant tobacco plant cell having a reduced level of nornicotine compared to a wild type tobacco plant cell， as well as to a tobacco plant， a plant material and a tobacco composition containing said cell. Also disclosed are a method for reducing the level of nornicotine in a tobacco plant， a method for reducing the level of N-nitrosonicotine (NNN) in a tobacco plant， as well as a method for reducing levels of nornicotine and N-nitrosonicotine (NNN) in a tobacco plant. Invention also relates to a method for producing dried plant material， preferably dried leaves or flowers with reduced levels of at least N-nitrosonicotine (NNN) in comparison with dried plant material based on wild-type plant. EFFECT: invention provides effective reduction of levels of nornicotine in a tobacco plant. 18 cl， 3 dwg， 1 tbl， 4 ex
