  • Silencing the Agrobacterium tumefaciens oncogenes

    Creator:
    Pitrak, Jennifer
    Abstract:
    Crown gall disease is an agricultural problem caused by the soil-borne bacterium, Agrobacterium tumefaciens. A. tumefaciens oncogenes cause transformed plant cells to overproduce the hormones, auxin and cytokinin. High hormone levels cause unorganized plant cell growth resulting in a gall. Control of crown gall disease is difficult because after plant...

  • Characterization of the LeIAA family of auxin-regulated genes in tomato (Lycopericon esculentum, Mill.)

    Creator:
    Nebenfuhr, Andreas
    Abstract:
    The plant hormone auxin regulates many aspects of plant growth and development. At the cellular level, auxin can stimulate cell division, cell elongation, and cell differentiation. Little is known about the molecular mechanisms that mediate auxin action at this level, although changes in gene expression have been implicated in each...

  • Interactions of auxin with ethylene and gravity in regulating growth and development in tomato (Lycopersicon esculentum, Mill.)

    Creator:
    Madlung, Andreas
    Abstract:
    Plant growth, development, and environmental responsiveness are dependent on hormone-induced gene expression. This dissertation reports multiple interactions between the plant hormones auxin and ethylene and investigates their contribution to the gravitropic response, elongation growth, adventitious root formation, callus and tracheary element initiation and growth, and flower development. Four mutants of...
