    Black shank disease, caused by the fungus Phytophthora parasitica var. nicotianae, is a major annual threat to all types of tobacco worldwide. Thus far, the main approaches to control this disease are the creation of resistant tobacco varieties and ...

    Expression of an apoplast-directed, phylloplanin-GFP fusion gene confers fungal resistance against Peronospora tabacina disease in a susceptible tobacco

    Kentucky Tobacco Research and Development Center, 1401 University Dr., Lexington, KY 40546, USA
    Tobaccos and certain other plants secrete phylloplanin glycoproteins to aerial surfaces where they appear to provide first-point-of-contact resistance against fungal pathogens. These proteins can be collected by water washing of aerial plant surfaces, and ...

    Natural variation in the acyl moieties of sugar esters produced by glandular trichomes in species of Nicotiana and Petunia

    MIHAYLOVA-KROUMOVA A.; ZAITLIN D.; WAGNER G.J.
    University of Kentucky, KTRDC, Lexington, KY, U.S.A.
    A unique feature of the glandular trichomes of Solanaceae species is their production of sugar esters. These metabolites have been shown to possess insecticidal, antifungal, and antibacterial properties. Sugar esters produced by tobacco (N. tabacum) ...

    A family of glycoproteins we have named T-phylloplanins are secreted to aerial surfaces of tobaccos by apparently specialized, short glandular trichomes. They can be recovered as leaf water washes (T-LWW), concentrated, and applied with spores to the leaf ...
