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...
Assessment of the microbiome associated with endangered orchids
(University of Missouri--Columbia, 2018)
or the potential effects of climate change. We studied two species of endangered terrestrial orchids in Missouri and, using DNA collected from soil and high throughput sequencing, evaluated the bacterial microbiome associated with these two orchid species....
Assessing the effects of anticoagulant rodenticides on non-target fish species
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Invasive rat species have negatively affected island ecosystems contributing to the decline and extinction of many endemic species. The eradication of rodents on islands can...
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. ...
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 ...
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...
Genetic diversity and distribution of the ringed salamander (ambystoma annulatum) across multiple spatial scales
(University of Missouri--Columbia, 2018)
that correspond to watershed boundaries. Within each cluster, I found evidence for decreased gene flow in recent generations, possibly due to the extensive timber harvest and land conversion of the CIH post European settlement. Over smaller spatial scales, I found...
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...
Tales of an 'invisible' life stage : survival and physiology among terrestrial juvenile ambystomatid salamanders
(University of Missouri--Columbia, 2019)
of the many amphibian species for which stage-specific data are lacking. Next, I reared larvae of five species (A. annulatum, A. maculatum, A. opacum, A. talpoideum, and A. texanum) from populations along an ~200 km latitudinal gradient in Missouri, USA...
Effects of prescribed fire and timber harvest on terrestrial salamander abundance, behavior, and microhabitat use
(University of Missouri--Columbia, 2014)
surveys for three years and used a statistical modeling approach that accounted for the tendency of terrestrial salamanders to be belowground and unavailable for surveys. I found that terrestrial salamander density at our Missouri Ozark study site ranged...
Mechanisms of the phototropic pathway
(University of Missouri--Columbia, 2018)
Plants are sessile organisms and therefore are limited in their ability to gather resources. Therefore, they have evolved several mechanisms that aid them in their quest to gather light, water and nutrients. One such ...
Identification, characterization and use of novel thermogenetic tools in drosophilia melanogaster
(University of Missouri--Columbia, 2019)
Extrinsic control of neural activity is necessary to decipher the neural mechanisms underlying behavior. Molecular tools that employ light (optogenetics) or temperature (thermogenetics) are primarily used for extrinsic ...
Mechanisms of polar growth in the alphaproteobacterial order rhizobiales
(University of Missouri--Columbia, 2019)
All bacteria elongate and divide to faithfully reproduce their cell shape. Understanding the mechanisms that drive bacterial morphology requires an intimate knowledge of how the cell wall is synthesized. During cell ...
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 ...
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 ...
Development of an amenable system for site-specific addition to a maize chromosome
(University of Missouri--Columbia, 2019)
Currently, transgenic maize is produced by random integration of a transgenes into the plant. This works for single genes, but not as well for multiple traits. Identifying plants that contain several transgenes becomes a ...
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 ...
