Buriscon regulated immune response in Drosophila melanogaster
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Bursicon is a heterodimeric neurohormone which binds to the receptor LGR2 and regulates various aspects in cuticle sclerotization and wing expansion ...
Adaptation of soybean to tropical environments for smallholder farmers
(University of Missouri--Columbia, 2018)
There are many traits that influence crop adaption to a new environment so that it can perform as a farmer would prefer. In these chapters, I have shown the influence of the genetic mechanisms behind pod shatter, days to ...
Horticultural crop response to synthetic auxins
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Rising adoption of dicamba-tolerant soybeans increases the potential exposure of grapes to dicamba, where off-target injury may occur via particle or ...
Characterizing hormesis and the in vitro effects of sub-lethal fungicide exposure in sclerotinia homoeocarpa
(University of Missouri--Columbia, 2018)
Dollar spot, caused by Sclerotinia homoeocarpa F.T. Bennett, is the most economically important disease of turfgrass. Dollar spot reduces aesthetics and playability of turfgrass, and when left uncontrolled can result in ...
Genotype, environment and GE interaction effect on soybean oil composition
(University of Missouri--Columbia, 2005)
Changing the content of the five major soy-oil fatty acids is important to enhance food, fuel and other applications of soybean oil. In addition to genetic effects, the growth environment can significantly affect oil ...
The underlying genetic control of maize root system architecture
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Maize (Zea mays ssp. mays) is one of the most widely cultivated and highest yielding grain crops in the world. The genetic and phenotypic diversity ...
Nested association mapping and accuracy of predicting genomic breeding value for agronomic and seed composition traits in three interspecific soybean populations
(University of Missouri--Columbia, 2019)
Given the narrow genetic base of soybean, discovering useful traits in exotic germplasm could increase the diversity in the current elite gene pool. However, it is essential to characterize beneficial alleles from the wild ...
Predator-prey interactions involving the soybean aphid (Hemiptera: Aphididae) in Missouri
(University of Missouri--Columbia, 2007)
The recently introduced soybean aphid, Aphis glycines Matsumura, is found in all soybean growing areas within Missouri. Despite soybean aphid's widespread distribution, it has reached economic threshold in few soybean ...
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)
Subterranean termite species in the genus Reticulitermes are ecologically and economically important in the United States. At least six species of the genus Reticulitermes are native from North American forests where they ...
Influence of some external conditions upon infection of hosts with powdery mildews
(University of Missouri--Columbia, 1914)
It has long been observed that one condition or another of the environment is favorable to the perpetuation and spread of fungous diseases. For example, it is very easy to recognize the close relation which exists between ...
Vegetation management along roadside and railroad right-of-ways
(University of Missouri--Columbia, 2018)
Efficient transportation of freight as well as motorists requires effective control of vegetation on right-of-ways (ROW's). Traditionally on railroad ROW's, residual herbicides are applied early in the growing season with ...
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. ...
Environmental regulation of the larval diapause of the southwestern corn borer, Diatraea grandiosella Dyar (Lepidoptera : pyralidae)
(University of Missouri--Columbia, 1973)
Diapause is a state of arrested growth or reproduction which is commonly found in insects (Lees, 1955). It may occur at any stage in the life cycle of an insect and is usually an important adaptation in the development of ...
Glyphosate resistance : pollen movement within a common ragweed (Ambrosia artemisiifolia L.) population and herbicide release from common waterhemp (Amaranthus rudis sauer) plants
(University of Missouri--Columbia, 2011)
Common ragweed and Common waterhemp are native, summer annual weeds distributed widely throughout the United States. Both weed species have developed resistance to the broad-spectrum herbicide glyphosate. Research was ...
Molecular characterization of soybean resistance to soybean cyst nematode
(University of Missouri--Columbia, 2009)
The soybean cyst nematode, Heterodera glycines, is a devastating pathogen to soybean worldwide. This obligate parasite establishes specialized feeding cells within host roots that are required for completion of the nematode ...
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 ...
A study of transcript profiling of soybean roots during nitrogen fixing symbiosis
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Nodulation is a symbiotic association between a host plant and its bacterium. The result of this interaction is the formation of a novel organ, the ...
Characterization of a diverse USDA collection of wild soybean (glycine soja siebold & zucc.) accessions and subsequent mapping for seed composition and agronomic traits in a RIL population
(University of Missouri--Columbia, 2018)
The relatively low genomic variation of current U.S. soybean [Glycine max (L.) Merill] cultivars constrains the improvement of grain yield, seed quality, and other agronomic traits within soybean breeding programs. Recently, ...
Biodiversity of ants (Hymenoptera: Formicidae) in restored grasslands of different ages
(University of Missouri--Columbia, 2006)
