Microrna regulation of bursicon in drosophila melanogaster
(University of Missouri--Columbia, 2014)
Bursicon is a heterodimeric neuropeptide hormone composed of two cystine knot subunits, bursicon α (burs α) and its partner, bursicon β (burs β). In Drosophila melanogaster, the heterodimer regulates wing expansion and the ...
Molecular mechanisms of stress tolerance in plants
(University of Missouri--Columbia, 2015)
Environmental stress conditions such as drought, salt stress and pathogenic fungi affect negatively plant growth and productivity. Therefore, it is necessary to search for new genetic components and strategies for improving ...
DNA insulator minimizing interactions between adjacent transgenes, transcriptomes contrasting callus induction of somatic embryogenesis in maize B73
(University of Missouri--Columbia, 2015)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In plants, transgene expression and inheritance patterns are either in some cases unpredictable or in most cases vary between different transgenic ...
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 ...
Suitability of cold-hardy loblolly and pitch x loblolly hybrid pines for commercial pine straw production in Missouri
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Pine straw production is a multi-million dollar industry, primarily in the Southern United States. The pine species, Pinus palustris Mill., P. elliotii ...
Vegetative growth and fruiting characteristics of black walnut
(University of Missouri--Columbia, 2011)
Three studies were conducted to evaluate sequential vegetative and fruiting characteristics of black walnut. 'Sparrow' vegetative shoots or those with one fruit were smaller in diameter than shoots with three fruits in ...
Genotypic and phenotypic predictors of low aflatoxin accumulation in Zea mays
(University of Missouri--Columbia, 2011)
Zea mays L. is one of the world's most important and widely grown crops and is susceptible to a wide range of plant pathogens. One fungal pathogen of particular concern is Aspergillus flavus Link, which is capable of ...
Influence of Manganese and other micronutrients on soybean yield and seed quality
(University of Missouri--Columbia, 2014)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Soybean (Gycine max [L.] Merr.) is the most popular oil seed crop in the United States and is the most widely planted row crop in the state of Missouri. ...
Integration of cultural practices and herbicide-resistant crop technologies for the management of glyphosate-resistant waterhemp in soybean
(University of Missouri--Columbia, 2014)
Common waterhemp (Amaranthus rudis Sauer) is the most prominent and troublesome weed in agronomic crops in Missouri, Iowa, and Illinois. As of 2014 in the U.S., herbicide resistance was present in waterhemp to one or more ...
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 ...
Synthesis and evaluation of sigma receptor ligands
(University of Missouri--Columbia, 2010)
Sigma receptors are unique binding sites located in the central nervous system (CNS) and peripheral organs. Two sigma receptor subtypes ([signma]1 and [sigma]2) have been described so far. It is known that the [sigma]1 ...
Influence of herbicide programs, weed height, and glufosinate and 2,4-D combinations on weed management in soybean resistant to 2,4-D
(University of Missouri--Columbia, 2012)
The introduction of transgenic crops with resistance to 2,4-D will provide growers with new weed management options in soybean. To better understand the utility of this technology in soybean production systems, field and ...
Identification of nontarget-site mechanisms of glyphosate resistance in roots and pollen of Amaranthus and Ambrosia
(University of Missouri--Columbia, 2014)
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 ...
