    Effects of application timing and methods on chlorantraniliprole residues in flue-cured tobacco

    VANN M.C.
    North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.
    Chlorantraniliprole is a narrow-spectrum insecticide that offers good to excellent control of tobacco budworm (Heliothis virescens) and Tobacco Hornworm (Manduca sexta). Due to its long residual control, narrow-spectrum activity, safety, and the loss...

    Development of an alternative system for seed-based tobacco haploid plant generation

    MOORE S.; KERNODLE S.P.; LEWIS R.S.
    Department of Crop and Soil Sciences, North Carolina State University, Raleigh, NC, U.S.A.
    Haploid plants can be extremely useful for expediting the production of new inbred lines, and also for rapidly converting female parental lines of new hybrids to cytoplasmic male sterility. Use of doubled haploid breeding can increase gain from...

    Genetic control of enantiomeric specificity of nicotine biosynthesis in tobacco

    ALLEN Z.; KERNODLE S.P.; STEEDE T.; DEWEY R.E.; LEWIS R.S.
    Department of Crop and Soil Sciences, North Carolina State University, Raleigh, NC, U.S.A.
    Living things frequently produce metabolites that can exist in optically pure form or as enantiomeric mixtures. Interestingly, enantiomers often confer different biological activities. Nicotine can exist naturally in the tobacco plant as either (R)-...

    Computational-based genomic, transcriptomic, and metabolic analyses of biosynthetic gene clusters in tobacco

    RABARA R.C.(1,2); LIU Hai(1); KUDITHIPUDI C.(2); TIMKO M.P.(1)
    (1) Department of Biology, University of Virginia, Charlottesville, VA, U.S.A.; (2) Altria Client Services LLC, Center for Research and Technology, Richmond, VA, U.S.A.
    Terpenes and terpenoids contribute to the aroma and flavor that influence consumer preferences in selecting plant-based products. Computational identification of biosynthetic gene clusters (BGCs) in plants can pave the way for future biosynthetic...

    Colchicine treated tobacco – changing biochemical composition of the leaves

    DELLA VECCHIA M.G.; ZHOU Ancheng; RABARA R.C.; QI Dong; SHEN Yanxin
    Altria Client Services LLC, Richmond, VA, U.S.A.
    Colchicine has been used in agriculture since the 1930s to induce polyploidy, or the duplication of chromosome sets, in plants. In addition to its use in inducing polyploidy, colchicine has also been studied for its potential effects on secondary...
