Functions and regulation of cytokinin glucosyltransferases

Creator:: Pineda Rodó, Albert
Abstract:: Cytokinins can be conjugated to N- and O-glucosides. While N-glucosylation generally leads to irretrievable loss of activity, O-glucosides are thought to play an important role in cytokinin storage and homeostasis since they can be hydrolyzed to the corresponding aglycones. The first zeatin O-glycosyltransferase genes isolated were ZOG1 and ZOX1 from...

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...

A revision of the Macrocheles glaber species group (Acari: Macrochelidae) using phylogenetic systematics

Creator:: Walter, David Evans, 1950-
Abstract:: The Macrocheles glaber species group contains many of the common mites which are associated with the dung of domestic animals. Species in the glaber group have been investigated for their use as biological control agents of synanthropic flies. Over 10,000 slide-mounted specimens of Macrocheles in the OSU Acarology Collection and...

Biological control of spider mites by the predatory mite Neoseiulus fallacis (Acari: Phytoseiidae) in ornamental nursery systems

Creator:: Pratt, Paul D.
Abstract:: We identified and evaluated a phytoseiid predator as a biological control agent of multiple spider mites pests that occur in ornamental nurseries. When comparing species, Neoseiulus fallacis (Garman) had a wider prey range than Galendromus occidentalis (Nesbitt), a higher probability of overwintering than Neoseiulus califomicus McGregor and was equally or...

Resistance mechanisms of Port-Orford-cedar to Phytophthora lateralis

Creator:: Oh, Eunsung
Abstract:: Breeding Port-Orford-cedar for resistance to Phytophthora lateralis, a causal agent of root disease, begins by screening, through artificial inoculation, phenotypically resistant trees selected from natural stands. The successful program selected tolerant or resistant POC parent trees for the purpose of disease management. Candidate resistant POCs were used in my dissertation...

Influence of photosynthesis and carbohydrates on adventitious root formation by leafy cuttings

Creator:: Davis, Tim D.
Abstract:: Many investigators have suggested that current photosynthate supply can limit adventitious root formation on leafy cuttings. Accordingly, studies were undertaken to determine the effects of altering photosynthesis and carbohydrate levels on adventitious root formation by leafy cuttings of a number of different species. Pea cuttings rooted at high CO₂ (1800...

Sugar uptake, fruit growth and carbon partitioning in the strawberry

Creator:: Forney, Charles F.
Abstract:: Sinks, plant organs which depend on the import of assimilates for growth, play a central role in determining assimilate distribution patterns within the plant. The strawberry fruit is a strong sink for dry matter and its effect on carbon partitioning and assimilation in the plant as well as the mechanism...

A comparison of two methods of divergent mass selection for heading date in two winter wheat (Triticum aestivum L. em Thell) crosses

Creator:: Frederickson, Leslie John
Abstract:: Responses to two cycles of mass selection for heading date, followed by selfing or intermating, were studied in two diverse winter wheat (Triticum aestivum L. em. Thell) crosses. Selection was bidirectional, resulting in early and late populations for each mating system, cycle, and cross. The influence of mass selection for...

Exploiting Hordeum vulgare subsp. spontaneum genetic resources : diversity analysis and germplasm development

Creator:: Matus, Iván Ariel
Abstract:: Wild barley (Hordeum vulgare subsp. spontaneum) could be a source of useful genes for improving cultivated barley. The useful genes present in Hordeum vulgare subsp. spontaneum may be new alleles at described loci, or these may be entirely new genes in the sense that there is limited allelic variation at...

Solutions to some linear evolutionary systems of equations : study of the double porosity model of fluid flow in fractured rock and its applications.

Creator:: Bodvarsson, Gudrun M.
Abstract:: The present work is a study of three degenerate, linear parabolic systems of equations, each of which represents a version of the so-called double porosity model for underground fluid flows in natural fractured rock. These systems of equations together with initial and boundary conditions describe single-phase flows in fluids, slightly...
