  • F-tests in partially balanced and unbalanced mixed linear models

    Creator:
    Utlaut, Theresa L.
    Abstract:
    This dissertation considers two approaches for testing hypotheses in unbalanced mixed linear models. The first approach is to construct a design with some type of structure or "partial" balance, so that some of the optimal properties of a completely balanced design hold. It is shown that for a particular type...

  • Explicit linear maximum likelihood estimation in mixed models

    Creator:
    Wulff, Shaun S.
    Abstract:
    Mixed models have been widely used to model data from experiments which have fixed and random factors. Often there is interest in the estimation of fixed effects and variance components. The likelihood procedure is a general technique that has been applied to such problems. This procedure can be computationally difficult,...

  • RFLP analyses of interspecific hybrids of Phaseolus

    Creator:
    Kuo, Mei
    Abstract:
    Gene transfer via interspecific hybridization within Phaseolus has been limited by abnormal hybrid development and the rapid loss of hybridity in subsequent generations. The most advanced embryo development occurs in P. vulgaris x P. coccineus where mature seeds form. However, the reciprocal cross still results in abnormal embryos unable to...

  • Characterization of cytokinin metabolic enzymes from Phaseolus

    Creator:
    Dixon, Susan C.
    Abstract:
    An enzyme catalyzing the formation of O-glucosylzeatin in immature embryos of P. lunatus was purified 2500 fold using ammonium sulfate precipitation followed by affinity and anion exchange chromatography. The enzyme uses trans-zeatin as substrate (Km 28 uM) but not cis-zeatin. ribosylzeatin, or dihydrozeatin. Both UDP-glucose and UDP-xylose can serve as...

  • Zeatin O-xylosyltransferase in Phaseolus vulgaris : immunological and molecular analyses

    Creator:
    Martin, Ruth C.
    Abstract:
    Cytokinins are a group of plant hormones mediating cell division and differentiation. Zeatin is a naturally occurring and highly active cytokinin that is rapidly metabolized in Phaseolus seeds. The metabolites and enzymes mediating the conversion have been studied extensively. Zeatin metabolic enzymes may be utilized in studying the regulation of...
