Switchgrass responses to manganese availability
(University of Missouri--Columbia, 2019)
in biomass production grown in the 0 [micro]M Mn treatment compared to 10-25 [micro]M Mn treatments was only observed for Alamo and KGraze, and not for Cave-in-Rock. Late in the season, relative chlorophyll contents of both switchgrass ecotypes were...
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 ...
Soybean seed components as affected by nodal position, environmental conditions, and irrigation
(University of Missouri--Columbia, 2005)
Soybeans (Glycine max [L.] Merr.) are a major source of vegetable protein and edible oil. The nutritional quality of these seed components depends upon the relative abundance of specific proteins and fatty acids. Additionally, ...
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 ...
Novel approaches in macroinvertebrate biomonitoring
(University of Missouri--Columbia, 2008)
The increasing popularity of benthic macroinvertebrate use for biological monitoring and assessment of lotic systems calls for new applications for regions with a lesser known fauna and an overall better understanding of ...
A digestive phospholipase a2 in Midguts of worker honey bees, Apis mellifera : significance in lipid nutrition and health
(University of Missouri--Columbia, 2018)
Phospholipase A2 (PLA2) catalyzes hydrolysis of the fatty acid moiety from the sn-2 position of phospholipids. At least 16 groups of PLA2s are known in mammals. In insects, PLA2s occur in several tissues, where they act ...
Development of high protein soybean experimental lines with enhanced sulfur amino acid content
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Soybean is one of the most important field crops grown in the United States. Commercial soybeans contain about 36 - 40 [percent] protein and 18 - 20 ...
Impact of alternate host phenology amd alternate hose-transgenic corn interactions on the Western corn rootworm (Coleoptera: Chrysomelidae)
(University of Missouri--Columbia, 2006)
weeds (4 to 6 weeks old) versus older grassy weeds. In behavioral tests, western corn rootworm larvae recognized younger roots (4 week old) as hosts but did not recognize older roots (7 or 10 week old) as hosts. Phenological changes in grassy weeds could...
Cotton and maize primary root growth responses to water deficit : comparative physiological and metabolic analysis
(University of Missouri--Columbia, 2019)
similarities or differences occur. A series of experiments was conducted to establish the foundation for directly comparing the metabolic responses to water deficit of cotton and maize primary roots. A modified vermiculite-culture seedling system was developed...
Biodiversity of ants (Hymenoptera: Formicidae) in restored grasslands of different ages
(University of Missouri--Columbia, 2006)
Grasslands are an endangered ecosystem. Unfortunately, few studies monitoring the health of these grasslands have included arthropods, thus leaving out a vital biodiversity component. Ants have been proven to be reliable ...
Conservation and divergence of reproductive phasiRNAs in flowering plants
(University of Missouri--Columbia, 2021)
Plant small RNAs (sRNAs) are important regulatory elements that fine-tune gene expression and maintain genome integrity by silencing transposons. They have critical roles in most pathways involved in plant growth and ...
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 ...
Prairie stream ecology : temporal and spatial patterns of macroinvertebrates
(University of Missouri--Columbia, 2018)
Tallgrass prairie streams and their fauna are understudied, due in part to their rarity. The composition of prairie stream communities differs geographically due to regionally and locally determined environmental characteristics ...
Behavioral responses of drosophila suzukii (diptera: drosophilidae) to olfactory and visual cues
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Selected fruit and leaf volatiles were assessed to determine their attractiveness to Drosophila suzukii Matsumura (Diptera: Drosophilidae). Two- and ...
Growth, photosynthesis, and carbohydrate dynamics of cotton during early development
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Stand establishment and early growth is critical for successful cotton (Gossypium hirsutum L.) production. Rapid early growth enhances the chances that ...
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, ...
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 ...
Role of the Arabidopsis peptide transporter AtOPT6 in heavy metal detoxification and plant-pathogen interaction
(University of Missouri--Columbia, 2007)
AtOPT6, is a member of oligopeptide transport (OPT) gene family. In Arabidopsis thaliana, there are nine members in the OPT gene family that are thought to be involved in peptide transport. Spacial and temporal expression ...
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 ...
