FIELD: biochemistry. SUBSTANCE: invention relates to a mutant tobacco plant cell for reducing nitrate levels in a mutant tobacco plant， as well as to a tobacco plant， a portion thereof， tobacco plant material， as well as to a tobacco composition containing said cell. Also disclosed is a method of reducing content of nitrates in at least part of a tobacco plant， comprising introducing into genome of tobacco plant one or more mutations within at least one allele of CLC family member of chloride channels， as well as a method of producing dried vegetable material of tobacco， preferably dried leaves， with reduced levels of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK). Invention also relates to a polynucleotide structure for reducing nitrate levels in a tobacco plant， as well as a vector for reducing nitrate levels in a tobacco plant， containing above described structure. EFFECT: invention allows efficient production of tobacco plant with reduced nitrate levels. 13 cl， 6 dwg， 2 tbl， 9 ex
