Characterization of soybean rooting depth in response to different environmental conditions
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] Soybean (Glycine max (L.) is currently grown throughout the world because it has been adapted to many environments and because of the high protein and oil content...
Herbage accumulation, nutritive value and nitrogen dynamics of a tall fescue forage system with either nitrogen fertilization or intercropped sunn hemp
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Elevated temperatures and declining precipitation during the summer results in tall fescue [Schedonorus arundinaceus (Schreb.) Dumort., nom. Cons] forage systems limiting cattle...
Interactions between cover crops, herbicides and weeds in soybean production systems
(University of Missouri--Columbia, 2018)
. An identical field experiment was conducted in 2016 in Arkansas, Indiana, Missouri and Wisconsin and repeated in Arkansas, Indiana, Mississippi and Missouri in 2017 to evaluate the most effective herbicide treatments for spring termination of regionally...
Recommendations for tree establishment in tall fescue-based silvopasture
(University of Missouri--Columbia, 2008)
Silvopasture offers Midwest landowners the opportunity to plant trees in their pastures without significant loss of forage production. However, much of the pasture in the Midwest is dominated by tall fescue (Schedonorus ...
Integrating cover crops into crop rotations in upstate Missouri
(University of Missouri--Columbia, 2018)
"There is an increasing emphasis on management strategies such as reduced tillage, use of cover crops, and implementation of conservation practices (i.e. terraces, no-till, and cropping systems) in Missouri cropping systems. By combining best...
Consequences of plant water limitation for aphids, their natural enemies, and insect communities
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Climate change is causing an increase in drought events around the world. Water limitation affects the quality and quantity of plant resources for herbivorous insects, resulting...
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...
Corn tissue nutrient response related to soil health and fertility
(University of Missouri--Columbia, 2021)
fertilizer decisions. End of season yield response to fertilizer may be improved by using both of these two diagnostic tools. Research conducted in 2019 and 2020 on 91 producer corn fields in Missouri encompassed many soil types, management practices...
Sulfur metabolism in Glycine max [L.] Merr : characterization of serine acetyletransferase and O-acetylserine (thiol) lyase
(University of Missouri--Columbia, 2006)
Soybean (Glycine max [L.] Merr) is considered an excellent protein source for both humans and livestock. Further improvement of quantity and quality of soybean protein is vital for maintaining the utility of this versatile ...
Partial characterization of Bt resistance and the bacteriome of western corn rootworm
(University of Missouri--Columbia, 2018)
Western corn rootworm (Diabrotica virgifera virgifera LeConte) and northern corn rootworm (Diabrotica barberi (Smith and Lawrence)) are major pests of maize in the USA. These pests have been managed with a variety of tactics ...
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 ...
Impact of alternate host phenology amd alternate hose-transgenic corn interactions on the Western corn rootworm (Coleoptera: Chrysomelidae)
(University of Missouri--Columbia, 2006)
followed by movement to Bt maize increased beetle emergence from Bt maize, fecundity of those that survived, and the number of viable eggs produced. In greenhouse trials, western corn rootworm larvae had significantly greater survival on younger grassy...
Investigation of genes involved in somatic embryogenesis and plant-Agrobacterium interactions through transcriptional profiling
(University of Missouri--Columbia, 2021)
Plant genetic engineering relies on the ability to transmit and express cloned DNA sequences in plant cells (transformation) as well as the capacity for the cells carrying this DNA to undergo division and differentiation ...
Resource extraction, resistance, and religion in Nicaragua
(University of Missouri--Columbia, 2019)
My dissertation examines the causes of protest over resource extraction in Nicaragua, and underlines the role of religion as a catalyst for sustained and successful challenges against resource extraction. With few exceptions, ...
