Characterization of Viral Communities in Soil, Activated Sludge, and Influent
(2009-07-15)
Viruses are the most abundant yet uncharacterized biological entities on the planet. This thesis is a survey of viral communities in soil, activated sludge (AS), and influent (IN). Both culture-dependent and culture-independent ...
Xyris tennesseensis: status survey, habitat restoration/management concerns, and relation to a new xyrid, Xyris spathifolia
(2009-02-23)
Xyris tennesseensis is a federally endangered, obligate wetland, perennial herb. It inhabits calcareous seeps, fens, and spring runs with a distribution restricted to the Interior Plateau and Ridge and Valley ecoregions ...
Functional Identification and Characterization of an Arabidopsis thaliana Gene Involved in Vitamin B6 Biosynthesis
(2009-02-23)
Vitamin B6 (pyridoxine) is a biological coenzyme
seemingly involved in environmental stress
tolerance and an important vitamin in human
nutrition produced in plants as well as fungi and
bacteria. A series ...
Response of Aquatic Biota to Changing Land Use Pattern in Streams of West Georgia, USA
(2009-02-23)
Watershed land use change is one of the most pervasive influences facing streams in the southeastern United States. In particular, watershed urbanization has a potentially dramatic impact on stream biota. Through direct ...
Pyridoxine (Pyridoxamine) 5'-phosphate Oxidase in Arabidopsis Thaliana
(2009-02-23)
Vitamin B6 is the collective term for a group of three related compounds, pyridoxine (PN), pyridoxal (PL) and pyridoxamine (PM), and their phosphorylated derivatives, pyridoxine 5'-phosphate (PNP), pyridoxal 5'-phosphate ...
Functional and Genetic Analysis of Plant Transcription Factors Involved in the Plant Growth Under Various Environmental Conditions
(2009-02-23)
Arabidopsis serves as a model system for the plant molecular biology. Many biotic and abiotic factors affect plant growth from seed germination to mature plant growth. External factors studied in our research include ...
Functional Durability Of A Quartz Crystal Microbalance Sensor For The Rapid Detection Of Salmonella In Liquids From Poultry Packaging
(2008-09-09)
Foodborne disease causes an estimated 4 to 76 million cases of food poisoning with 5,000 associated deaths annually in the United States at a cost of $6.5 –34.9 billion. In poultry products, Salmonella is the most common ...
Polyketide Synthase Pathway Discovery from Soil Metagenomic Libraries
(2009-07-21)
Polyketides are structurally diverse bacterial secondary metabolites, many of which have antibiotic or anti-cancer activity. Modular polyketide synthase (PKS) enzymatic complexes contain conserved ketoacyl synthase (KS) ...
Microhabitat Associations of Wintering Birds in a Southeastern Bottomland Forest within the Eastern Gulf Coastal Plain of Florida
(2009-07-16)
I examined microhabitat characteristics affecting the occupancy of wintering birds in a southeastern bottomland forest with repeated point counts at 186 sites. Models were derived a priori based on published literature and ...
Stream-breeding amphibian responses to land use distrubances
(2009-04-29)
Conversion of land from an undeveloped state into agricultural or urban areas is widespread. Urban areas in particular are growing both in size and number globally. Such land use changes can potentially have negative ...
