Genetic architecture and marker-assisted breeding for salt tolerance in soybean
(University of Missouri--Columbia, 2018)
Salinity is one of the major abiotic stresses that inhibits plant growth and causes seed yield loss in soybean. Although a major gene for salt tolerance on chromosome (Chr.) 3 was mapped, cloned and characterized, it does ...
Molecular characterization of CLE peptide mimicry during cyst nematode pathogenesis
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Plant-parasitic cyst nematodes establish intimate parasitic relationships with their hosts by penetrating the root as motile juveniles and migrating intracellularly until...
A multi-dimensional investigation into the effects of flooding on the physical, chemical and biotic properties of riparian soils
(University of Missouri--Columbia, 2008)
flooding. Simulated floods were created under greenhouse and field laboratory settings to assess these changes as well as the effect of soil chemistry changes on germination and seedling growth. In addition, riparian forests in northwest Missouri were...
Investigation of rare alleles in maize using the zea synthetic doubled haploid population
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The biology of rare alleles is important to our understanding of genotype-to-phenotype relationships. Understanding the role of rare alleles can aid in the selection...
Body size and shape in insular environments and applications of the island rule in biological anthropology
(University of Missouri--Columbia, 2021)
The discovery of small-bodied hominin fossils in 2004 on the island of Flores, Indonesia, unearthed a large debate within biological anthropology. This debate has exemplified that there are questions and research areas ...
"Sin mujeres no hay revolución" : transversal feminist politics in the digital mediated activism of the Argentine collective Ni una menos
(University of Missouri--Columbia, 2019)
While the advent of the Internet and digital social networks has opened opportunities for global connectivity, participation, and broadcasting to agents outside the media, corporations and the state, inequities structuring ...
Thinking locally : provincialism and cosmopolitanism in American literature since the Great Depression
(University of Missouri--Columbia, 2007)
Thinking Locally produces an account of twentieth-century literary history that counters the literary-historical over-reliance on wars as framing events. Eschewing the standard break between pre-World War II and post-World ...
Animals in ancient Greek warfare : a study of the elephant, camel, and dog
(University of Missouri--Columbia, 2020)
My dissertation asserts that the study of animals is integral to the thorough understanding of the ancient military landscape, and three animals in particular warrant particular attention: the elephant, camel, and dog. I ...
Authoritarian successor parties and political protest in Asia
(University of Missouri--Columbia, 2020)
How does an authoritarian successor party (ASP) interact with civil society in East and Southeast Asia? Does an ASP's control over the executive and legislature increase or decrease protest movements? Do ASPs effectively ...
Development and validation of standardized sampling protocols for assessing freshwater mussel populations in Missouri
(University of Missouri--Columbia, 2017)
step in assessing populations. We surveyed 14 sites in the Meramec River Basin in East-central Missouri to determine the effectiveness of visual sampling methods and to determine the effects of habitat variability on the effectiveness of these methods...
Storied possessions : post-household disbandment older adult placemaking through meaningful belongings
(University of Missouri--Columbia, 2018)
If older adults do not age-in-place, one of their last residential moves involves significant downsizing referred to as household disbandment. During this process, older adults divest themselves of possessions, change ...
Nutrients, chlorophyll and bacterial fecal indicators in coves and open water areas of Lake of the Ozarks, Missouri
(University of Missouri--Columbia, 2009)
Urban development and use of septic tanks in porous soils of Lake of the Ozarks poses a threat to public health via leaching into drinking wells and coves used for swimming. During 2 summers, phosphorus (TP), nitrogen (TN), ...
Applications of ancestry estimation in cattle population genetics
(University of Missouri--Columbia, 2019)
Accounting for ancestry and cryptic population structure is important in population genetic data analysis. The estimation of ancestry can help elucidate the effects of admixture or stratification on allele and genotype ...
My year pooping in a bucket : lifestyle, cultural, and social movements in the "node" at Dancing Rabbit ecovillage
(University of Missouri--Columbia, 2018)
What happens between the most visible aspects of social movements? When protestors put down their signs, petitioners hang up their clipboards, and movement organizations contract, there are several theories about what ...
Hydrodynamic characteristics and capillary-assisted heat transfer enhancement of non-condensing/condensing two-phase flows
(University of Missouri--Columbia, 2020)
Interfacial characteristics of two-phase flows were studied through visualization experiments and numerical simulation using computational fluid dynamics (CFD) based on the volume-of-fluid (VOF)-continuum surface force (CSF) method...
