  • 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...

  • Auxin and cytokinin interaction in tomato (Lycopersicon esculentum Mill.)

    Creator:
    Coenen, Catharina
    Abstract:
    The phytohormones auxin and cytokinin control plant development through a complex network of interactions which include synergistic, additive, and opposite effects whose mechanisms are unknown. The auxin-insensitive diageotropica (dgt) mutant provided a tool to dissect the relationship between auxin- and cytokinin-induced responses in tomato. Morphological, physiological, and molecular data support...

  • Molecular genetic analysis of fruit development in tomato (Lycopersicon esculentum, Mill.)

    Creator:
    Balbi, Virginia
    Abstract:
    Plant hormones regulate progression through the different phases of plant development in response to endogenous and environmental cues. Gene expression studies, as well as genetic and molecular analysis of mutants with altered hormonal responses, are two common approaches to elucidate hormone response pathways. This dissertation compares ovary and fruit development...
