Biology and control of Amur honeysuckle
(University of Missouri--Columbia, 2013)
the biology and control options for this plant. The objectives of this research were to: a) determine efficacy of various herbicides using postemergence and basal bark applications; b) determine the means of seed spread and time at which Amur honeysuckle seeds...
The effects of drought stress and western corn rootworm feeding on maize root biology
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Drought and western corn rootworm (WCR), Diabrotica virgifera virgifera, can have substantial impacts on the potential yield of maize, Zea may L. Maize ...
Physiological responses of continental (summer-active) and mediterranean (summer-dormant) tall Fescue to cold stress and identification of underlying QTL for fall growth and winter survival
(University of Missouri--Columbia, 2010)
We describe three experiments; the first two experiments were conducted in a greenhouse and with the use of cold chambers. The first experiment determined the effect of endophyte (Neotyphodium ceonophialum) presence under ...
Taxonomic composition and distribution of saucer bugs (Heteroptera: Nepomorpha: Naucoridae) of Tanzania
(University of Missouri--Columbia, 2012)
to harbor the mycobacterium responsible for Buruli ulcer in Africa, although transmission is not known. Therefore, to provide a sound foundation for future biological, ecological, and epidemiological investigations, a study to document the taxonomic...
Mechanisms of non-consumptive effects of parasitoid wasps on aphid populations : enhancing aphid suppression by increasing natural enemy and plant diversity /
(University of Missouri--Columbia, 2016)
Predators are typically evaluated for their potential effectiveness as natural biological control agents by examining traits related to their consumptive relationship with an herbivore. For example, voracious predators with a high prey attack rate...
Genetic engineering of sorghum and switchgrass for improved biofuel production
(University of Missouri--Columbia, 2016)
among the public laboratories. Of randomly analyzed independent transgenic events, 40-50% events carried a single copy of integrated T-DNA. The system developed here should be beneficial to sorghum biology study and genome exploration including genome...
Synthesis and evaluation of sigma receptor ligands
(University of Missouri--Columbia, 2010)
number of CNS disorders and the [sigma]2 receptor is involved in tumor proliferation among others. Because of the important biological functions of the [sigma] receptor, development of structure activity relationships (SAR) can aid in the identification...
Genetic and molecular analysis of soybean cyst nematode virulence
(University of Missouri--Columbia, 2017)
The soybean cyst nematode (SCN) Heterodera glycines is the most economically important pathogen of soybean, capable of causing large scale yield loss on a global scale. Current management practices utilize host resistance, ...
Elucidating the role of jasmonate metabolites in jasmonic acid signaling
(University of Missouri--Columbia, 2017)
, the amidohydrolases ILL6 and IAR3 cleave JA-Ile at the amide bond into free jasmonic acid and -Ile. In contrast to the well-established function of JA-Ile in mediating JA-dependent responses, biological functions of other JA metabolites are less clear. Identification...
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 ...
Integrated management of the invasive weed, cut-leaved teasel (Dipsacus laciniatus L.) along a Missouri highways
(University of Missouri--Columbia, 2008)
Cut-leaved leaved teasel is an invasive, exotic, and noxious weed in Missouri. Biennial plant infest roadsides and undisturbed areas. Studies regarding seed biology, detection, and control measures were conducted to improve teasel management along a...
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 how community measures...
Poison hemlock (conium Maculatum L.) : biology, implications for pastures and response to herbicides
(University of Missouri--Columbia, 2008)
Poison hemlock is a biennial, toxic and invasive weed that grows along roadsides, pastures and low-disturbed areas. Research was conducted to determine seed ecology, growth characteristics and response to herbicides. Seed ...
Role of microRNAs in the legume - rhizobium nitrogen fixing symbiosis
(University of Missouri--Columbia, 2019)
such damage to the environment is through biological nitrogen fixation between legume species and Rhizobium bacteria. The symbiotic interaction between legume plants and rhizobia results in the formation of root nodules, specialized organs within which...
Herbage accumulation, nutritive value and nitrogen dynamics of a tall fescue forage system with either nitrogen fertilization or intercropped sunn hemp
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Elevated temperatures and declining precipitation during the summer results in tall fescue [Schedonorus arundinaceus (Schreb.) Dumort., nom. Cons] ...
Exploring the symbiotic relationship of plants and microbes by mass spectrometry imaging
(University of Missouri--Columbia, 2019)
to extensive chemical runoff into waterways, increases in use of fossil fuel-derived energy with concomitant increases in greenhouse gas emissions, and accumulating costs correlated with fertilizer distribution. In contrast, biological nitrogen fixation (BNF...
Armillaria species in the Missouri Ozarks forests
(University of Missouri--Columbia, 2005)
In the Missouri Ozark Mountains, species of the white-rot wood decay fungus Armillaria contribute to oak decline. To investigate the relationships of Armillaria species with their hosts, the DNA fingerprinting technique ...
A study of transcript profiling of soybean roots during nitrogen fixing symbiosis
