    Downregulation of a putative nitrate transporter gene substantially reduces the accumulation of TSNAs in air-cured tobaccos

    GOEPFERT S.(1); BOVET L.(1); LU J.(2); CAMPANONI P.(1); LEWIS R.S.(2); DEWEY R.E.(2)
    (1) Philip Morris Products S.A. (part of Philip Morris International group of companies), PMI R&D, Neuchâtel, Switzerland; (2) North Carolina State University, Department of Crop Science, Raleigh, NC, U.S.A.
    Air-cured Burley tobacco leaves typically exhibit high levels of nicotine-derived nitrosamine ketone (NNK) and N'-nitrosonornicotine (NNN). It has been previously demonstrated that leaf nitrate accumulation in air-cured tobaccos serves as the source ...
