Methodological approaches for sound training in underepresented learners: a case study with american toads (Anaxyrus americanus)
(University of Missouri--Columbia, 2021)
), with almost no research on amphibians. Many animals remain unstudied, even though they may possess unique and powerful adaptations to respond to environmental stimuli that can be useful for learning and cognition research. Inspired by the efforts to increase...
The power of synteny : deep evolutionary insights from comparative genomics
(University of Missouri--Columbia, 2021)
tree-species tree incongruence. In Chapter III, as published in Abrahams et al., 2020, I utilize a microsynteny network and phylogenetic inference to investigate the origin and diversification of the MAM/IPMS gene family. I uncover unique MAM-like genes...
Conservation genetics of conflict in the Asian elephant, Elephas maximus
(University of Missouri--Columbia, 2021)
The Asian elephant (Elephas maximus) is an endangered species whose distribution spans 13 countries in south, southeast, and insular Asia. The primary threats to the survival of this species include direct conflict, primarily ...
Brassicales to Brassica : integrating phylogenomics and population genomics
(University of Missouri--Columbia, 2020)
to this diverse order. The focus of my dissertation has been to use phylogenomics and population genomics to understand the evolution of the Brassicales, as well as the important crop species Brassica oleracea. Within the Brassicales, the family Brassicaceae...
Role of non-hypophototropic hypocotyl[3] (NPH[3]) in regulation of phototropism in Arabidopsis
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Light is arguably one of the most important environmental factor that not only provides the plant with its energy needs but also cues to modulate its ...
Uncovering the genetic basis of seed amino acid composition in arabidopsis using a multi-omics integrative approach
(University of Missouri--Columbia, 2021)
belongs to the Glutamate Family (Arginine, Proline, Glutamine, and Glutamate). Although Glutamine is not an EAA, it is a major nitrogencontaining amino acid that is transported to the seed; thus it's regulatory control is of particular interest. I harness...
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 ...
From unique killers to a jumbo genome - isolation and characterization of phages that infect the plant pathogen, Agrobacterium tumefaciens
(University of Missouri--Columbia, 2019)
). The atypical domain structure of PPH, along with the absence of obvious accessory proteins, suggest PPH may function independently to mediate host cell lysis. Contrary to the narrow host range of the phage, expression of PPH from an inducible promoter inhibits...
The genetic and physiological basis of total energy budget in different nutritional environments
(University of Missouri--Columbia, 2020)
Organisms need to adapt to dynamic environments over time. An organism consumes and stores a finite amount of resources that are used for all daily tasks. In order to survive and thrive, they must allocate these finite ...
Coupling, membrane conductance, and ion channel mRNA profiles in the establishment and maintenance of network activity in the crustacean cardiac ganglion
(University of Missouri--Columbia, 2021)
at one hour, which may be maintained or regress at twenty-four hours. Additionally, we find that membrane properties and excitability are not maintained from one to twenty-four hours, suggesting a failure to maintain homeostasis or that additional...
Characterization of the relationship between radiographic grading and biomarkers in patients with knee osteoarthritis
(University of Missouri--Columbia, 2020)
"Osteoarthritis (OA) is a whole-joint degenerative disease, affecting more than 25% of the adult population. Currently, OA is most commonly diagnosed based on radiographic documentation. However, radiographic grading is ...
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 ...
Centromere function and evolution in maize (Zea mays)
(University of Missouri--Columbia, 2006)
of repetitive elements showing that certain families of retrotransposons are enriched in the heterochromatic regions flanking the centromere. Finally, I describe a novel chromosomal rearrangement, an inversion with a breakpoint in the centromere that splits...
