    • Induction of hairy roots on cultivated soybean genotypes and their use to propagate the soybean cyst nematode. 

      Savka, Michael; Ravillion, B.; Noel, G.; Farrand, Stephen (American Phytopathological Society: Phytopathology, 1990)
      Ten soybean (Glycine max ) genotypes were evaluated for hairy root induction by four strains of Agrobacterium rhizogenes . Influence of inoculation site was assessed by infecting hypocotyls and cotyledons on germinated ...

    • Induction of pseudoactinorhizae by the plant pathogen Agrobacterium rhizogenes 

      Berg, R. Howard; Liu, Lixua; Dawson, Jeffrey; Savka, Michael; Farrand, Stephen (American Society of Plant Biologists: Plant Physiology, 1992-02)
      Infection of Elaeagnus angustifolia cotyledonary wounds by Agrobacterium rhizogenes strain NCPPB 2659 resulted in the formation of pseudoactinorhizae on roots differentiated from callus. These pseudoactinorhizal root nodules ...

    • Mannityl opine accumulation and exudation by transgenic tobacco 

      Savka, Michael; Farrand, Stephen (American Society of Plant Biologists: Plant Physiology, 1992-02)
      Three genes from the TR region of pTi15955 were introduced into tobacco (Nicotiana tabacum L.) to direct the synthesis of the mannityl opines from hexose sugars and glutamine or glutamate. Opines were present in all tissue ...

    • Modification of rhizobacterial populations by engineering bacterium utilization of a novel plant-produced resource 

      Savka, Michael; Farrand, Stephen (Nature Publishing Group: Nature Biotechnology, 1997-04)
      The ability to catabolize distinct nutrients produced by a plant may be a factor in the successful colonization of that host by a bacterium when in competition with other rhizosphere microorganisms. We tested this hypothesis ...

    • Regeneration of transgenic soybean (Glycine max) plants from electroporated protoplasts 

      Dhir, Sarwan; Dhir, Seema; Savka, Michael; Belanger, Faith; Kriz, Alan; Farrand, Stephen; Widholm, Jack (American Society of Plant Biologists: Plant Physiology, 1992-05)
      Transgenic soybean (Glycine max [L.] Merr.) plants were regenerated from calli derived from protoplasts electroporated with plasmid DNA-carrying genes for a selectable marker, neomycin phosphotransferase (NPTII), under the ...

    • Translocation and exudation of tumor metabolites in crown galled plants 

      Savka, Michael; Black, Robert; Binns, Andrew; Farrand, Stephen (American Phytopathological Society: Molecular Plant-Microbe Interactions, 1996-05)
      Crown gall tumors are induced on susceptible plants by pathogenic strains of Agrobacterium. These neoplastic plants cells produce metabolites, called opines, which provide a source of nutrients to colonizing agrobacteria. ...
