    Cucumber mosaic virus-IB induced endoplasmic reticular stress in Nicotiana benthamiana

    SHEN Lili; LI Fangfang; HE Qingyun; LI Ying; YANG Jinguang; WANG Fenglong
    Tobacco Research Institute, Chinese Academy of Agricultural Sciences, Qingdao, Shandong, P.R. China
    The cellular translation machinery is hijacked by large amounts of viral proteins upon virus infection. The unfolded proteins accumulated in the endoplasmic reticulum (ER) results in ER stress (ERs), which triggers the unfolded protein response (UPR)...

    Many recessive resistances against potyviruses are mediated by eukaryotic translation initiation factors (eIF4E). In tobacco, the va resistance gene commonly used to control PVY corresponds to a large (almost 1Mb) deletion affecting a copy of eIF4E...

    Nicotine reduction: use of modelling approach to evaluate unintended consequences, a focus on illicit trade

    GUO M.; VERRON T.; CAHOURS X.; COLARD S.
    SEITA-Imperial Tobacco Limited, Fleury-les-Aubrais, France
    In 2015, the WHO TobReg issued an advisory note recommending a strategy for reducing nicotine in tobacco to substantially lower levels. The authors considered that regulation of nicotine levels would lead to a decrease of smoking prevalence. In their...

    Sponged tobacco: meteorological and altitude influence on curing methods in flue-cured systems in South Africa

    DU PLESSIS H.(1); ROOS H.J.(2)
    (1) Limpopo Tobacco Processors (Pty) Ltd, Rustenburg, South Africa; (2) Tobacco Producer, Rustenburg, South Africa
    Flue-cured tobacco in South Africa has over the years produced high amounts of sponged leaf, although the reaping of leaf was done at the correct physiological time. We asked if this was due to incorrect curing methods and due to meteorological...

    Developing flue-cured tobacco hybrids with combined resistance to granville wilt and root-knot nematodes and angular leaf spot in Malawi

    SIBANDE L.A.G.O.; CHAMANGO A.M.Z.; GOMONDA R.W.J.
    Agricultural Research and Extension Trust (ARET), Lilongwe, Malawi
    Flue-cured tobacco production in Malawi is constrained by both soil-borne (root-knot nematodes and Granville wilt) and aerial borne (angular leaf spot and alternaria brown spot) diseases. To address these multiple challenges, a breeding programme was...

    Soil applications of maleic hydrazide do not control tobacco axillary bud growth

    VANN M.C.; WHITLEY D.S.
    North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.
    Increased focus on residues of the plant growth regulator Maleic Hydrazide (MH) have prohibited some U.S. producers from applying the suckercide to control tobacco axillary buds. As such, an alternative to the conventional foliar application of the...
