Identification and characterization of M cells in the mammalian conjunctiva
(University of Missouri--Columbia, 2007)
The M cell is a morphologically and functionally distinct epithelial cell found in the follicle associated epithelium (FAE) above organized lymphoid tissue at distinct locations along mucosal surfaces. By sampling antigens ...
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...
Uncovering the genetic basis of seed amino acid composition in arabidopsis using a multi-omics integrative approach
(University of Missouri--Columbia, 2021)
Seeds are a vital source of protein in the diet of humans and livestock. However, protein composition in the seed is low, comprising about 10 percent of the total composition in the seed. Additionally, protein quality in ...
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 ...
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...
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 ...
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 ...
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 growth and development...
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)
Neural networks produce critical rhythmic behaviors throughout an animal's lifespan, despite growth, differing environments, and changes in physiological state. This requires networks which balance stability in their ...
