Molecular characterization of genetic resistance to soybean cyst nematode in soybean line SS97-6946
(University of Missouri--Columbia, 2008)
. Seeds from 160 F2:3 families were evaluated against races 1, 2, 3 and 5 for SCN bioassay following standard protocol. The ratio observed between resistant to susceptible F2:3 families revealed that SCN resistance involved three recessive genes for both...
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 ...
Cotton and maize primary root growth responses to water deficit : comparative physiological and metabolic analysis
(University of Missouri--Columbia, 2019)
Cotton (Gossypium hirsutum L.) and maize (Zea mays L.) are important economic crops that can suffer significant yield loss under drought. Cotton and maize root systems have fundamentally different architectures, in addition to cotton being a...
Comparing the diversity, geographic distribution, and intraspecific variation of subterranean termites (Reticulitermes: Isoptera: Rhinotermitidae) occuring in woodlands and urban environments of Missouri using morphology and 16s mtDNA
(University of Missouri--Columbia, 2007)
approximately 600 samples of termite colonies collected during 2004 and 2005 in nine conservation areas, nine cities located near these conservation areas, and from home infestations occurring at many different locations within the state. Reticulitermes flavipes...
Grasshopper and bee communities on Missouri prairies : comparing reconstructions and remnants
(University of Missouri--Columbia, 2018)
Tallgrass prairies once occupied a large swath of central North America, but now face the combined challenges of habitat loss and fragmentation. In Missouri, where less than 1% the historical prairie remains, prairies are ...
An attentional theory of issue-carrying capacity
(University of Missouri--Columbia, 2018)
A plethora of research in cognitive and behavioral psychology showed that there are significant differences in the way men and women process political and social information. It has been widely accepted that women show ...
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...
The influence of fusarium species on sweet potato plant performance, root yield and quality
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Sweet potato (Ipomoea batatas (L.) Lam.) is a global important food crop, that has recorded an increase in the consumption, and demand for especially ...
Impact of grazing stockpiled tall fescue of lactating beef cows
(University of Missouri--Columbia, 2006)
Two experiments are described, in which fall-calving cow-calf pairs grazed stockpiled tall fescue at three different endophyte infection levels (20, 51, and 89%) and four forage allowances (2.25, 3.00, 3.75, and 4.50% of ...
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 ...
Armillaria species in the Missouri Ozarks forests
(University of Missouri--Columbia, 2005)
species, specifically red oak species. Analyses of isolates collected from stumps in 2003 and 2004 revealed no significant difference in the recovery of A. mellea, A. gallica, or A. tabescens from red and white oak species stumps....
Switchgrass responses to manganese availability
(University of Missouri--Columbia, 2019)
promising biofuel species for sustainable production of bioenergy feedstock. As a NADME C4 species, switchgrass may have a high requirement for Mn for optimum growth. However, little is known about switchgrass responses to Mn availability at present...
The role of the vasculature in iron allocation and sensing in plants
(University of Missouri--Columbia, 2019)
affect people whose diets heavily rely on highly processed foods, which are energy dense and micronutrient-poor. By number, moderate to severe anemia in the U.S. population increased from 1.0% to 1.9%, comparing data of 2003-2004 to 2011-2012 census (5...
Comparing mosquito communities of various patch-matrix landscape combinations in central Missouri, with implications for developing models to forecast abundances of important mosquito taxa
(University of Missouri--Columbia, 2010)
environmental conditions within different landscape configurations may help approximate a model for predicting the risk of encountering these disease vectors. Therefore, the goals of the research were to 1) describe the mosquito fauna of the various patch...
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)
(Xanthium strumarium L.) on total biomass yield and nutritive values. Results from these experiments indicate that a variety of herbicide treatments will provide good control of several common pasture weed species, but that infestations of these weeds may...
Examination of host genetic determinants of the hypersensitive response in Nicotiana edwardsonii to CaMV and TMV
