Biology and management of cut-leaved Teasel (Dipsacus laciniatus L.) in central Missouri
(University of Missouri--Columbia, 2006)
Cut-leaved teasel is a biennial invasive weed that grows along roadsides and low disturbed areas. This research was to determine growth characteristics, herbicide efficacy, and seed production of teasel. Growth characteristics ...
Cover crop and rotation intensity effects on soil health and yield in corn-soybean cropping systems
(University of Missouri--Columbia, 2020)
In the Midwest, corn-soybean [Glycine max (L). Merrill] is the dominant biennial cropping system, which covers approximately 75% of the arable land surface (Hatfield et al., 2007; Plourde et al., 2013). The growing demand for corn (Zea mays L...
Field pennycress management in upstate Missouri
(University of Missouri--Columbia, 2017)
Field pennycress has the potential to serve as a cover and oilseed crop. A seed oil content of 25 to 36 percent has created interest in pennycress domestication. This research evaluated management strategies for growing ...
Integrated management of the invasive weed, cut-leaved teasel (Dipsacus laciniatus L.) along a Missouri highways
(University of Missouri--Columbia, 2008)
under field conditions, seed viability was only 6.1%. Cut-leaved teasel can be detected among other species in a highway environment with greater 80% accuracy. Application of the herbicide aminopyralid in both May and October, combined with sowing tall...
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)
of Missouri. Ecological studies as well as integrated management may benefit from the information provided in this study....
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...
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 ...
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 ...
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 ...
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...
Identification and characterization of glyphosate-resistant common ragweed
(University of Missouri--Columbia, 2007)
A revolution in production agriculture has occurred over the past decade; the development and use of herbicide-resistant crops. Glyphosate is an effective, broad spectrum and offers flexible application timing with minimal ...
Influence of entomopathogenic fungi from forest and urban habitats on founding pairs of reticulitermes flavipes (rhinotermitidae)
(University of Missouri--Columbia, 2015)
by Reticulitermes flavipes primary kings and queens, control of founding pairs by preventing establishment may be an important method of termite control. Using locally collected Beauveria and Metarhizium, this research compared mortality and sublethal effects...
Molecular characterization of CLE peptide mimicry during cyst nematode pathogenesis
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Plant-parasitic cyst nematodes establish intimate parasitic relationships with their hosts by penetrating the root as motile juveniles and migrating ...
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...
Role of microRNAs in the legume - rhizobium nitrogen fixing symbiosis
(University of Missouri--Columbia, 2019)
-transfer compounds, such as ATP. Although 78 [percent] of the atmosphere is diatomic nitrogen, this form is inert and unavailable to plants due to the strong nitrogen-nitrogen triple bond. Plants can only absorb nitrogen in the forms of NH4+ or NO3-. Most...
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 ...
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...
