The role of Arabidopsis SRFR1 in defense against the beet cyst nematode Heterodera schachtii and beet army worm Spodoptera exigua
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Plants are constantly exposed to a variety of pathogenic microbes and pests. Thus, plants have developed diverse mechanisms to fine-tune defense responses to different types...
Identification of an extracellular adenosine 5'-triphosphate receptor in Arabidopsis thaliana
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Adenosine 5'-triphosphate (ATP) is a well-known energy currency in all organisms. However, ATP also acts as a signaling molecule when it is secreted outside the cell. The long...
Source-sink interactions shape herbivore-induced defense responses in Arabidopsis thaliana
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Plant tissues are not attacked uniformly, nor are they uniformly responsive to insect herbivores, in part because they are modular organisms made up of source and sink tissues...
Identification of an interaction network of Arabidopsis transcription factors and MAP kinases involved in chitin signaling and pathogen defense
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Chitin, found in the fungal cell walls, is an established elicitor of plant defense responses. Our previous study, using the ATH1 Affymetrix microarrays and the quantitative...
Establishment and yield of bioenergy miscanthus on clayplan soil ladscapes
(University of Missouri--Columbia, 2015)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Bioenergy crop Miscanthus × giganteus has been well studied for its establishment and yield in Europe and certain parts of the US Midwest but little has been done to investigate...
Evaluation of pre-formulated micronutrients products and their interactions with glyphosate on corn growth and yield
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Pre-formulated micronutrient fertilizer products are advertised to improve yields and may increase the nutritional content of Missouri's crops. The increase in yields would...
The balance between plant immunity and development: interactions of SRFR1 and TCP transcription factors
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Plants have developed a highly effective immune system for resisting microbial pathogens. One layer of the plant innate immune system is effector-triggered immunity. This immune...
Prairie stream ecology : temporal and spatial patterns of macroinvertebrates
(University of Missouri--Columbia, 2018)
patches to enable recolonization of streams after disturbance. Leptophlebia konza Burian was thought to be restricted to its type locality of Konza Prairie, Kansas; however, a population was discovered at Hi Lonesome Prairie in Missouri during an extensive...
Accessibility of public services : city government institutions and service spatial distribution
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Public services are central to the purpose of city government, and scholars have found that government institutions affect policy and budgetary decisions. I use the locations...
Coordinating the overall stomatal response of plants : rapid leaf-to-leaf communication during light stress
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Plants, being sessile organisms, have evolved unique mechanisms enabling them to rapidly react to ever-changing environmental conditions. In nature, light is one...
Effect of temperature on a soybean [Glycine max (L.) Merr.] mutant
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Soybean is influenced by temperature and light, and global warming has been shown to reduce soybean yields. In this study we tested the germination of TM-Miniature, a soybean...
Utilizing radiotracer and genetic approaches to determine the regulation of sucrose export in maize leaves
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] To sustain plant growth, development, and ultimately crop yield, carbohydrates must be transported from their site of synthesis in leaves to distant parts of the plant...
Application of CRISPR/Cas9-mediated genome editing for studying soybean resistance to soybean cyst nematode
(University of Missouri--Columbia, 2016)
Soybean cyst nematode (SCN) Heterodera glycines has become one of the most economically important pathogens of soybean in the world. The main strategy of SCN management is planting resistant soybean cultivars. The main ...
Feeding the beast : macroeconomic drivers of leadership responses to foreign policy action and the gendered consequences for human trafficking
(University of Missouri--Columbia, 2019)
How do the gendered macroeconomic and macropolitical structures of the international system exacerbate the rise in human trafficking? In this dissertation project, I use a mixed method approach to examine the relationship between domestic leadership...
An attentional theory of issue-carrying capacity
(University of Missouri--Columbia, 2018)
of the extent to which differing cognitive styles affect the scope of problem identification and prioritization. Integrating insights from both political behavior and psychology research, this dissertation argues that women's lower cognitive threshold of urgency...
Vegetation management along roadside and railroad right-of-ways
(University of Missouri--Columbia, 2018)
to restrict weed emergence. Field studies in central Illinois (three), Missouri (one), and Kansas (one) were established in 2015 and 2016 to compare fall single versus multiple application timings of residual herbicides from fall through the following summer...
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...
Cover crop and rotation intensity effects on soil health and yield in corn-soybean cropping systems
(University of Missouri--Columbia, 2020)
In the Midwest, corn-soybean [Glycine max (L). Merrill] is the dominant biennial cropping system, which covers approximately 75% of the arable land surface (Hatfield et al., 2007; Plourde et al., 2013). The growing demand for corn (Zea mays L...
