RSS 1.0Division of Biological Sciences (MU)
The Division of Biological Sciences at MU offers a unique integration of world-class research, award-winning graduate and undergraduate training, and outstanding community outreach. Our faculty research programs include the acquisition of new knowledge through basic research, and coordinated translational research to improve human health, our food supply, and our environment. Our graduate training programs emphasize the excitement of discovery and the development of individual creativity and critical reasoning skills, with graduate mentors who are experts at the frontiers of their field. In undergraduate education, as in our graduate programs, we emphasize the excitement of discovery and the development of individual creativity and critical reasoning skills, providing an excellent foundation for advanced study or direct entry into the workplace. Because science exposure in the pre-college years is critical to the development of both scientists and informed citizens, we also offer special outreach programs for secondary school science teachers and their students in Missouri.

Periconceptional, gestational, and lactational exposure to unconventional oil and gas chemical mixture alters energy expenditure in adult female mice
(University of Missouri--Columbia, 2018)Unconventional oil and gas (UOG) processes involves injection of pressurized water, chemicals, and suspended solids thousands of feet under the surface to release natural gas and oil. Previously our lab has shown antagonist ... -
Mechanisms of photoreceptor mediated responses in photomorphogenesis and phototropism
(University of Missouri--Columbia, 2018)Photoreceptor facilitated light perception provides plants with critical environmental information from which they can direct their growth. We investigated the early photomorphogenic responses in Glycine max and Glycine ... -
The ecological roles of amphibians and subsidies in ponds
(University of Missouri--Columbia, 2018)Freshwater ponds are often underappreciated landscape features, despite the fact they comprise a major portion of all freshwater ecosystems. Ponds support diverse food webs and species not found in other habitat types. ... -
Plasticity of neurons in mouse major pelvic ganglia in response to loos of physiological input in cases of nerve injury and spinal cord injury
(University of Missouri--Columbia, 2018)Autonomic dysfunctions present significant effects on day to day functions of spinal cord-injured patients. Most people with spinal cord injury (SCI) reported a desire to recover autonomic functions such as bladder and ... -
Roles for the adhension molecule Contactin2 in the development and function of neural circuits in zebrafish
(University of Missouri--Columbia, 2018)Neuronal migration and axon guidance are critical developmental processes that are essential for establishing functional neural circuits underlying complex cognitive and motor functions. Precise neuronal migration and axon ... -
Understanding the effects of maternal undernutrition in early gestation on placental development in late gestation
(University of Missouri--Columbia, 2018)Chronic diseases such as cardiovascular disease and diabetes are on the rise among the U.S. population. Heart Disease is the leading cause of death in the US and is responsible 610,000 deaths per year. A suite of risk ... -
Stimulus specific adaptation in the hearing system of Neoconocephalus katydids (insecta : orthoptera)
(University of Missouri--Columbia, 2017)Stimulus Specific Adaptation (SSA) is a fundamental response that identifies novel signals within a repetitive background noise. It is well characterized in the vertebrate auditory system, but has been studied only in a ... -
Neuronal changes underlying altered biophysical properties of reticulospinal neurons following spinal cord injury in the lamprey
(University of Missouri--Columbia, 2017)Following a severe spinal cord injury (SCI), the descending axons of reticulospinal (RS) neurons are damaged, resulting in paralysis below the site of the injury. For higher vertebrates, including humans, RS neurons are ... -
Genetic and physical interactions of Arabidopsis TOPLESS related 2 with regulators of plant innate immunity
(University of Missouri--Columbia, 2017)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Plants are constantly subjected to attack from pathogens. In order to defend themselves, plants have evolved a robust immune system. However, activation ... -
C4 photosynthetic evolution: Sub-types, diversity, and function within the grass tribe Paniceae
(University of Missouri--Columbia, 2017)Most plants convert sunlight into chemical energy using a process known as C[subscript 3] photosynthesis. However, some of the world’s most successful plants instead use the C[subscript 4] photosynthetic pathway which ... -
Models of gestational diabetes and offspring outcomes in mice
(University of Missouri--Columbia, 2017)Gestational diabetes mellitus (GDM) is the most common pregnancy disorder. GDM pregnancies result in offspring that are more likely to develop metabolic syndrome in adolescence than the background population. As offspring ... -
Eph/ephrin involvement in skeletal muscle development and regeneration
(University of Missouri--Columbia, 2017)Skeletal muscle development and regeneration is one of the best-described areas of vertebrate biology, due in large part to muscle cells’ characteristic sequence of specification, determination, and differentiation. However, ... -
Analysis of cell signaling during floral abscission in arabidopsis
(University of Missouri--Columbia, 2017)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The shedding of plant organs is known as abscission. Floral abscission in Arabidopsis is regulated by two related receptor¬-like protein kinases (RLKs), ... -
Evolution and development of the paired spikelet trait in maize and other grasses (Poaceae)
(University of Missouri--Columbia, 2017)Meristems are composed of groups of tightly-regulated cells that coordinate the number of stem cells in the central zone of the meristem with the number of cells migrating to organ primordia in the peripheral zones of the ... -
