    Development of genetically engineered tobacco forms resistant to herbicides and parasites by expression of cytochrome P450 monooxygenase genes

    YORDANOVA E.
    Institute of Genetic Engineering, Kostinbrod, Bulgaria.
    Tobacco is of one of the traditional crops with special importance for Bulgarian agriculture and economy. At the same time tobacco is the main model plant in modern biotechnology. Many environmental factors (diseases, weeds, parasites and insects) lead to ...

    Transgenic tobacco for efficient control of Orobanche spp

    VALKOV V.; ATANASSOVA S.; SLAVOV S.; BOSSOLOVA S.; BATCHVAROVA R.; ATANASSOV A.
    Institute of Genetic Engineering, Kostinbrod, Bulgaria.
    Several structurally distinct classes of herbicides including the sulfonylurea (Glean), imidazolinone (Pivot) as well as asulam (Asulox, Rhône-Poulenc) and Basta (Hoechst AG) were used for transformation of tobacco cultivars via Agrobacterium tumefaciens. ...

    In vitro germination of Orobanche seeds in presence of tobacco root exudates and plant growth regulators

    BOSSOLOVA S.; SLAVOV S.; BATCHVAROVA R.
    Institute of Genetic Engineering, Kostinbrod, Bulgaria.
    Broomrape (Orobanche ramosa L.) is an obligate root parasite which causes severe reduction of tobacco quality and yield. Seeds of the parasite germinate only in the presence of the host plant. An in vitro system for seed germination was established in ...

    Effect of Phytophthora parasitica var nicotianae (race 0) culture filtrate on bud formation and direct organogenesis in tobacco stem explants

    BLAGOEVA-NIKOLAEVA V.; SLAVOV S.
    Institute of Genetic Engineering, Kostinbrod, Bulgaria.
    The effect of Phytophthora parasitica var. nicotianae (Ppn) race 0 culture filtrate (CF) on direct organogenesis in tobacco stem explants was evaluated using six tobacco cultivars, which were selected based on their field reaction to Ppn. The culture ...

    Virus resistance in transgenic tobacco cultivars expressing the coat protein of tobacco spotted wilt virus

    STOEVA P.; IVANOVA L.; NICOLAEVA V.; SLAVOV S.; VARSANO L.; YANKULOVA M.; UCHVAROVA R.; ATANASSOV A.
    Institute of Genetic Engineering, Kostinbrod, Bulgaria.
    By Agrobacterium binary vector system, the coat protein gene of the Bulgarian isolate of TSWV-La strain was introduced and expressed in a number of widespread Bulgarian Oriental varieties. Three binary vectors, carrying the coat protein gene of TSWV in ...

    Possibilities for biological control of tobacco black-shank with Bacillus cereus

    BLAGOEVA-NIKOLAEVA V.; SLAVON S.; VARSANO L.
    Institute of Genetic Engineering, Kostinbrod, Bulgaria.
    This paper describes the results of trials in which selected isolate of B. cereus was applied to tobacco seedling roots to determine its effect on the control of black-shank disease in artificially infected soil. The roots of tobacco plants from several ...
