The Role of Arabidopsis RNA-Dependent RNA Polymerase Genes 3, 4 and 5 in Antiviral Defense

Creator:: Lowery, Nicholas C.
Abstract:: RNA silencing plays a critical role in plant defense against viral infection. Plants use virusderived small interfering RNA to target and silence invading viruses. The antiviral silencing pathway can be broken down into three conceptual stages: initiation, amplification, and systemic movement. The molecular mechanisms of silencing initiation are not well...

Methionine recycling in fruit studies on the metabolism and function of selected intermediates

Creator:: Gander, Lise Marie K.
Abstract:: This research has focussed upon both the in vitro and in vivo characterization of the recycling pathway leading from 5'-deoxy-5'-methylthioadenosine to methionine in fruit. In addition to contributing towards polyamine biosynthesis and other important cellular functions, in plant tissues these events also serve to generate the hormone ethylene. A broad...

Characterization of a new Lactobacillus species infectious for salmonid fish

Creator:: Hiu, Stephen Fooklen
Abstract:: A new Lactobacillus species is proposed to include 17 strains of a bacterium from rainbow (Salmo gairdneri) and cutthroat trout (Salmo clarki), and chinook salmon (Oncorhynchus tshawytscha). The bacterium was isolated most frequently from fish stressed by handling or spawn ing. Phenotypically, the strains belong to the family Lactobacillaceae and...

Investigations of T cell costimulation and autoimmunity in mice, and development of flow cytometric methods to assess lymphocyte stimulation in dogs

Creator:: Weatherill, Amy R.
Abstract:: Proper immune function is indispensable, as failure to mount an immune response against a pathogen can lead to serious complications or even death. T cells act by enhancing the activation of phagocytic cells as well as the activation of B cells. Their widespread influence on an immune response makes optimal...

Chemical and Genetic Investigations of Toxic Freshwater Cyanobacterial Blooms for Improved Monitoring and Understanding of Lake Ecology

Creator:: Collart, Lindsay P.
Abstract:: Toxin production by cyanobacterial harmful algal blooms (cyanoHABs) in freshwater systems has lasting ecological and human impacts. Nutrients, light availability, hydrology, and microbial community composition impact the frequency and intensity of toxic cyanoHABs. Climate change will exacerbate toxic cyanoHABs, making real time and predictive monitoring a vital tool for managing...

Impacts of microbial chemical interactions on marine plankton physiology

Creator:: Moore, Eric R.
Abstract:: The bioavailability of chemical compounds in the marine environment fundamentally influences the growth and physiology of microorganisms. Organic and inorganic chemicals that are produced by some marine plankton can be consumed by other plankton for energy production, growth, or to initiate essential physiological processes. Cultures of the diatom Thalassiosira pseudonana,...

Comparative Genomics of Freshwater Bloom-Forming Cyanobacteria and Associated Organisms

Creator:: Driscoll, Connor B.
Abstract:: The advent of improved DNA sequencing technologies has allowed the analysis of various microbial communities. Bloom-forming freshwater cyanobacteria can produce toxins and taste-and-odor compounds that can negatively affect drinking water supplies. Here, I have employed second- and third-generation sequencing technologies to characterize bloom-forming freshwater cyanobacterial genomes and their associated heterotrophic...

Effect of mercury on β-galactosidase activity : possible relationship to lactose intolerance

Creator:: LaChance, Michele Collette
Abstract:: The ability of mercury to inhibit β - galactosidase activity from cell-free extracts of Streptococcus lactis, Escherichia colt and intestinal homogenates of hogs, female rats, and humans was studied. Mercuric acetate was added in vitro to all sources of β - galactosidase except for the rats, which were placed on...

Cloning and biochemical characterization of the hectochlorin biosynthetic gene cluster from the marine cyanobacterium Lyngbya majuscula

Creator:: Ramaswamy, Aishwarya V.
Abstract:: Cyanobacteria are rich in biologically active secondary metabolites, many of which have potential application as anticancer or antimicrobial drugs or as useful probes in cell biology studies. A Jamaican isolate of the marine cyanobacterium, Lyngbya majuscula was the source of a novel antifungal and cytotoxic secondary metabolite, hectochlorin. The structure...
