    Combining gene expression, metabolomics, and conventional breeding to increase the nitrogen use efficiency of Burley tobacco

    KUDITHIPUDI C.; FREDERICK J.; XU D.; ADAMS A.; PRAMOD S.; WAREK U.; STRICKLAND J.A.
    Altria Client Services LLC, Research, Development and Regulatory Affairs, Richmond, VA, U.S.A.
    High rates of nitrogen fertilization are required currently for cultivation of Burley tobacco to achieve the desired leaf yields and qualities. However, Maryland type tobaccos are grown using a nitrogen fertilization rate that is ~60-70 % lower than...
