Understanding the effects of maternal undernutrition in early gestation on placental development in late gestation
(University of Missouri--Columbia, 2018)
acid transporter, in restricted placentae.These changes in placentae from dams fed a nutrient restricted diet suggestsome compensation to ensure adequate nutrients are available to the fetus forproper development.I also examined the effects MUN...
Friends in high places : ecology of mycorrhizal associations in alpine plant communities
(University of Missouri--Columbia, 2010)
Mutualisms are ubiquitous in nature, yet these interactions often vary in strength and persistence. This variation raises the questions of what determines whether mutualisms persist or vanish, and how does variation in the ...
The Agrobacterium tumefaciens min system contributes to the regulation of cell division
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In A. tumefaciens, the essential FtsZ protein is located at the growth pole before shifting to the mid-cell right before division. Recruitment of FtsZ to mid-cell is required...
The secret lives of African forest elephants: using genetics, networks, and telemetry to understand sociality
(University of Missouri--Columbia, 2012)
Knowledge of social structure is important to understanding the overall evolution and behavioral ecology of a species as it ultimately influences spatial patterns and gene flow. This dissertation focuses on the social ...
Establishing a foundation for large DNA transfer to artificial minichromosomes and B insert platforms in maize
(University of Missouri--Columbia, 2019)
In plants, conventional genetic engineering methods limit the number of available traits that could potentially improve the quality of agriculture. Agrobacterium-mediated transformation and biolistic bombardment are tools ...
Novel approach to assessment of efficacy of platelet inhibition by clopidogrel and aspirin in healthy dogs
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Introduction: Antiplatelet therapy, including clopidogrel and aspirin, is used to decrease the risk of thromboembolism in dogs. However, efficacy of therapy...
Flipping the switch : regulation of proliferation and differentiation in adult muscle stem cells
(University of Missouri--Columbia, 2011)
Adult muscle stem cells or satellite cells are the committed somatic stem cells responsible for maintenance and regeneration of adult skeletal muscle tissue. Skeletal muscle is capable of multiple rounds of complete ...
Genetic diversity and distribution of the ringed salamander (ambystoma annulatum) across multiple spatial scales
(University of Missouri--Columbia, 2018)
Species distributions are governed by a complex suite of abiotic and biotic interactions that govern movement of individuals and are variable through time and space. These dynamic processes, such as shifts in temperature ...
Approaches for unveiling the kinetic mechanisms of voltage gated ion channels in neurons
(University of Missouri--Columbia, 2019)
Ionic currents drive cellular function within all living cells to perform highly specific tasks. For excitable cells, such as muscle and neurons, voltage-gated ion channels have finely tuned kinetics that allow the ...
Elucidation of the genetic control of carbohydrate partitioning in Zea mays
(University of Missouri--Columbia, 2019)
Carbohydrate partitioning, the process of transporting carbohydrates from sites of synthesis in hotosynthetic tissue to developing sink tissues, is crucial for the growth, development, and yield in plants and crops. ...
Genome-wide exploration of direct GBX2 target genes and their contributions to mouse development
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The cells that comprise the vertebrate nervous system require molecular cues to determine their cellular position, identity and their ability to make appropriate connections...
Developmental programming by xenoestrogens
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Xenoestrogens (XE) are chemicals in the environment that mimic the body's natural steroidal estrogens. Developmental exposure to XE may interfere with normal hormonal signaling...
Periconceptional, gestational, and lactational exposure to unconventional oil and gas chemical mixture alters energy expenditure in adult female mice
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] 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...
Phylogenomics of orchids and their mycorrhizal fungi : trees, diversity, and the pursuit of symbiosis
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Phylogenetic trees show us how organisms are related and provide frameworks for studying and testing evolutionary hypotheses. To better understand the evolution of orchids...
PopZ and FtsZ coordinate polar growth termination and cell division in Agrobacterium tumefaciens
(University of Missouri--Columbia, 2018)
Understanding how bacterial cells expand their cell walls is an important question with relevance to development of antibiotics. While many studies have focused on the regulation of bacterial elongation utilizing lateral ...
The impacts of partner abundance on benefits from facultative pollination mutualism
(University of Missouri--Columbia, 2010)
Partner abundance affects costs and benefits in obligate mutualisms, but its role in facultative partnerships is less clear. I investigated this topic in a small alpine pollination web in the Colorado Rocky Mountains ...
From unique killers to a jumbo genome - isolation and characterization of phages that infect the plant pathogen, Agrobacterium tumefaciens
(University of Missouri--Columbia, 2019)
Bacteriophages and their lytic peptides can protect plants from phytopathogens such as Agrobacterium tumefaciens. To better understand mechanisms of phagemediated host killing, we isolated and characterized five lytic ...
