The development of cleaner, cheaper and more reliable alternative energy sources such as biofuels is necessary to meet the increasing demand for energy production and environmental sustainability. The biofuel that is expected to be widely used around the globe is cellulosic ethanol. In this regard, the temperate grass Brachypodium is currently in use for studying how to modify grass crops for biofuel feedstock production. However, functional genomics tools have not been fully developed in Brachypodium, and its cell wall biogenesis pathway is not understood.
The neural networks that organize the motor pattern for locomotion are located in the spinal cord. These networks normally receive descending inputs from the brain that activate them and direct them to modify their output for variable behavior. These inputs are lost after spinal cord injury (SCI). As a consequence, the neurons begin to change their properties, in ways that might be deleterious to eventual recovery from SCI.
The Plant Ontology (PO) is a unique and effective tool to bridge communities that emphasize their research in different disciplines, such as genetics, molecular biology, cell biology, taxonomy, botany, and genomics.
Providing shade is critical for cattle in feedlot as it can provide a shield from direct solar load, especially for animals with black and dark-colored hair coats. The objectives were to determine whether shade made a significant difference in thermal responses (animal activities and vaginal temperature), and determine the effect of hair-coat color on body temperature due to solar exposure. We found that providing shade lowered vaginal temperature, especially for the black Angus and the dark-red colored MARC III, which both have hair-coat color of higher capacity to absorb solar load.
The nutritional adequacy of the food supply and promotion of healthy dietary habits are increasingly identified as major public health objectives to promote longer lives and a better quality of living throughout the life cycle. Minerals are particularly essential components of the diet. Calcium and iron are needed for many biological reactions within the body, and adequate intakes are essential to maintain optimum health.
Cancer cells are characterized by uncontrolled cell proliferation, genome instability, accumulation of mutations, and aneuploidy. Many of these characteristics are associated with misregulated DNA replication. Our laboratory uses yeast, fruit flies, and mice as model systems to study the regulation of DNA replication.
I am studying the consequences to food composition and quality due to the unintended effects of transgenic crop improvement. I am using tomato as a model system, examining the range of phenotypic variance in fruit composition in diverse conventional tomato varieties. The variation observed will be used to estimate the significance of variation observed in a set of transgenic tomatoes with altered fruit ripening my laboratory has generated.
The horse, like other domesticated species, has been molded by selection into a variety of forms. While the horse is not a common source of food in the United States, the horse industry has a significant economic impact, estimated at $39 billion dollars annually (American Horse Council, 2005). This impact translates into a $102 billion dollar annual contribution to the U.S. Gross Domestic Product. The horse also represents a relatively new frontier in genetic research.
My research project addresses the neural mechanisms of small-motor network plasticity using the pyloric network of the lobster stomatogastric ganglion as a model system. We are searching for fundamental principles that govern motor network operation that will apply to more complex motor networks, such as the one governing locomotion in humans.
I study how insects function, especially how they obtain enough nutrients from their food to grow and reproduce, sometimes with the help of "friendly" bacteria.
