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...
Molecular cloning and characterization of regulatory enzymes in threonine biosynthetic pathway from soybean
(University of Missouri--Columbia, 2007)
Soybeans (Glycine max [L.] Merr.) are a good source of protein and oil. Despite being a very good source of protein, soybeans nutritional value is limited by low proportion of sulfur amino acids methionine and cysteine ...
Chloroplast GFP expression in tobacco plants agroinfiltrated with tobacco mosaic virus based vectors
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Viruses are submicroscopic infectious particles comprising of nucleic acid and protein which can replicate only within living host cells. TMV is a positive single-stranded RNA...
Characterization of raffinose synthase genes in soybean
(University of Missouri--Columbia, 2009)
As the use of soy products in foods and feeds increases, it is ever more important to consider the nutritional value of each component of the seed. The carbohydrate component is largely composed of sucrose, raffinose, and ...
A study of transcript profiling of soybean roots during nitrogen fixing symbiosis
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Nodulation is a symbiotic association between a host plant and its bacterium. The result of this interaction is the formation of a novel organ, the nodule that is able to fix...
Influence of herbicides application on weed and tall fescue management and grazing distribution in Missouri pastures
(University of Missouri--Columbia, 2012)
One weed that is of concern in Missouri pastures that can be detrimental is Northern dewberry (Rubus flagellaris Willd.). This weed can be detrimental due its production of spines which can injure grazing animals and also ...
Abscisic acid: interactions with ethylene and reactive oxygen species in the regulation of root growth under water deficit
(University of Missouri--Columbia, 2011)
Abscisic acid (ABA) is involved in several responses to plant water deficits, including an important role in root growth maintenance. Studies of the ABA-deficient maize mutant viviparous 14 (vp14) showed that ABA-deficiency ...
Identification and management of glyphosate-resistant annual bluegrass (Poa annua L.)
(University of Missouri--Columbia, 2010)
Annual bluegrass is the most problematic weed on golf courses in the Transition Zone and Southern United States. Applications of glyphosate are common on dormant zoysiagrass to remove winter annual weeds. In 2007, a suspect ...
Viability, vigor, and field performance of a low phytic acid, high phytase activity soybean line, CAPPA
(University of Missouri--Columbia, 2009)
Plants store inorganic phosphate (Pi) in seeds as phytic acid (PA). Phytic acid chelates essential macro and micronutrients in developing seeds forming phytate, which is nutritionally unavailable to monogastric livestock. ...
Function of abscisic acid in maintenance of maize primary root growth under water deficit
(University of Missouri--Columbia, 2006)
Previous studies suggested that ABA accumulation is required to maintain maize primary root elongation under water deficit and that one of the functions of ABA is to restrict ethylene evolution. These studies were conducted by using carotenoid...
Molecular characterization of soybean resistance to soybean cyst nematode
(University of Missouri--Columbia, 2009)
The soybean cyst nematode, Heterodera glycines, is a devastating pathogen to soybean worldwide. This obligate parasite establishes specialized feeding cells within host roots that are required for completion of the nematode ...
Genetic engineering of soybean using candidate genes to improve drought tolerance
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Drought is one of the major abiotic stresses which affect productivity in soybean. Plants respond and adapt to drought stress through various biochemical and physiological...
Development and validation of a DNA microarray for analysis of the Bradyrhizobium japonicum transcriptome
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Bradyrhizobium japonicum, forms a nitrogen fixing symbiosis with soybean. The ability to survive in soil environments, colonize the rhizosphere and establish effective plant...
Molecular characterization of soybean squalene synthases (GmSQSs) and genetic engineering for enhanced phytosterols in Arabidopsis seeds
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Squalene synthase (SQS), which converts fanesyl diphosphate (FPP) to squalene, represents a crucial branch point of the isoprenoid pathway and is considered a key enzyme...
The underlying genetic control of maize root system architecture
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Maize (Zea mays ssp. mays) is one of the most widely cultivated and highest yielding grain crops in the world. The genetic and phenotypic diversity of maize facilitate its use...
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...
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...
Role of microRNAs in the legume - rhizobium nitrogen fixing symbiosis
(University of Missouri--Columbia, 2019)

Influence of herbicide applications and common pasture weeds on total forage yield and nutritive values in tall fescue pastures and hayfields in Missouri
(University of Missouri--Columbia, 2009)
The addition of several new herbicides labeled for pastures or hayfields has led many growers to question their options for weed management in these environments. In addition, little is known about the influence of common ...
