Resistance management of the western corn rootworm (Diabrotica virgifera virgifera) : behavior, survival and the potential for cross resistance on Bt corn in the field, greenhouse and laboratory
(University of Missouri--Columbia, 2013)
The Environmental Protection Agency recently registered seed blend refuges for two of the transgenic Bt corn products targeting the western corn rootworm (WCR), Diabrotica virgifera virgifera LeConte. Larval movement between ...
Predator diversity impacts herbivore abundance and behavior with cascading effects on the prevalence of a vector-borne plant pathogen
(University of Missouri--Columbia, 2013)
There is growing concern about the loss of biodiversity; particularly of organisms at higher trophic levels, such as predators, which face a disproportionately higher risk of extinction. As predator diversity declines there ...
Seed protein, oil, and yield of soybean genotypes with high and normal oleic acid concentration
(University of Missouri--Columbia, 2013)
Soybeans with seed oil high in oleic acid content have been developed and are desired by oil processors because of improved oxidative stability for broader use in food, fuel and other products. Conventional soybean lines ...
Biology and control of Amur honeysuckle
(University of Missouri--Columbia, 2013)
Amur honeysuckle (Lonicera maackii) is an invasive weed species that is present in a majority of the United States. This weed has the ability to displace native plant species and develop monocultures in undisturbed areas. ...
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 ...
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 ...
Effects of maturity and production stage on residual feed intake classification of beef cows
(University of Missouri--Columbia, 2013)
The objective of this research was to determine if the postweaning residual Feed intake (RFI) classification of beef heifers remain consistent as the animals matured, went through different stages of production and were ...
Improving soybean seed composition through molecular breeding for raffinose family oligosaccharides, lectin, and trypsin inhibitors
(University of Missouri--Columbia, 2013)
In 2011, soybeans were planted on 75 million acres in the US and the total crop value exceeded $35 billion. After the oil is extracted from the soybean, the remaining high protein fraction is made into meal to be used in ...
Evaluation of agrochemical interactions and application timings in corn and soybean
(University of Missouri--Columbia, 2013)
Due to the increase in glyphosate-resistant (GR) weeds, two agrochemical companies have developed soybeans with resistance to 2,4-D and dicamba in an effort to provide growers with new options for the control of problematic ...
Historical landscape interactions and patterns of invasion by subterranean termites (Isoptera: Reticulitermes) in subdivisions of different ages
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The subterranean termite genus Reticulitermes includes some of the most economically destructive termites in the United States, where it is estimated ...
Effect of rootstock on vegetative growth, yield, and fruit composition of Norton grapevines
(University of Missouri--Columbia, 2013)
Norton is an important commercial grape cultivar commonly grown in Missouri and the surrounding region because of its wine quality and disease resistance. However, own-rooted Norton vines typically produce fruit with high ...
Dual use switchgrass :managing switchgrass for biomass production and summer grazing
(University of Missouri--Columbia, 2013)
Two studies were conducted on established switchgrass plots at Columbia and Mount Vernon, Missouri. The Columbia site was located on Mexico silt loam, and the Mount Vernon site on Viraton silt loam. The first study examined ...
Soil characteristics and subsequent corn development following partial corn residue removal in a no-till, corn-soybean rotation
(University of Missouri--Columbia, 2013)
If producers employ corn (Zea mays L.) residue removal for ethanol production, soil and subsequent corn development characteristics could be affected. Little research has evaluated partial corn residue removal from baling ...
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 ...
Phytic acid phosphorus and inorganic phosphorus composition in seeds of soybean lines with independent inositol pentakisphosphate 2-kinase mutations
(University of Missouri--Columbia, 2013)
Soybean [Glycine max (L.) Merr] seeds contain a large amount of phosphorus (P), which is stored as phytic acid (PA). PA is indigestible by nonruminant livestock and considered an anti-nutritional factor because PA chelates ...
Co-ordinated expression of CRTB, At-VTE3, and VTE4 to enhance pro-vitamin A and vitamin E in transgenic soybean
(University of Missouri--Columbia, 2013)
Although soybean is an excellent general nutritional source, it is not very rich in particular vitamins. The main goal of this study is to enhance both pro-vitamin A (carotenoids) and vitamin E (tocopherols) content in ...
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 ...
Comparison of mosquito communities collected from differing livestock locations and an examination of phenotypic traits exhibited by four latitudinally separated populations of Aedes albopictus (Skuse)
(University of Missouri--Columbia, 2013)
Mosquito presence and fitness play key roles in the spread of zoonotic pathogens affecting human as well as livestock and wild populations of vertebrates. This study examined the (1) differences between mosquito communities ...
Managing sweet sorghum for optimum ethanol yield in Missouri
(University of Missouri--Columbia, 2013)
Sweet sorghum has the potential in Missouri for production as a biofuel feedstock, but little is known of the crop's yields and appropriate nitrogen management for optimizing ethanol yields. This thesis is a collection of ...
