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 ...
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 ...
Reaction of soybean cultivars to waterlogged soil
(University of Missouri--Columbia, 2006)
Irrigating soybean prior to an extensive rain can result in waterlogged soil that may cause root damage and plant death. Some soybean cultivars tolerate waterlogged soils. The objective of this study was to evaluate tolerance ...
The sublethal effects of ecdysone agonists on the attractiveness, responsiveness, fertility and fecundity of oriental fruit moth, a comparative examination with codling moth on larval feeding damage
(University of Missouri--Columbia, 2006)
The ecdysone agonists methoxyfenozide and tebufenozide are designed to affect the larval stage of Lepidopteran pests. Recent studies have reported sublethal effects on the adults of several tortricid apple tree pests exposed ...
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 ...
Investigation of resistance to Heterodera glycines (scn) in soybean plant introductions (pi) 467312 and 507354
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Soybean cyst nematode (SCN) Heterodera glycines Ichinohe is the most serious pest of soybean [Glycine max (L.) Merr.] in the world. The effectiveness ...
Identification and management of glyphosate-resistant annual bluegrass (Poa annua L.)
(University of Missouri--Columbia, 2010)
Annual bluegrass is the most problematic weed on golf courses in the Transition Zone and Southern United States. Applications of glyphosate are common on dormant zoysiagrass to remove winter annual weeds. In 2007, a suspect ...
Molecular characterization of soybean squalene synthases (GmSQSs) and genetic engineering for enhanced phytosterols in Arabidopsis seeds
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Squalene synthase (SQS), which converts fanesyl diphosphate (FPP) to squalene, represents a crucial branch point of the isoprenoid pathway and is ...
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 ...
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 ...
Plasticity of soybean (Glycine max (l.) Merrill) root system development under mild water deficit
(University of Missouri--Columbia, 2008)
Drought is the major abiotic factor limiting soybean yield in the US. Under water deficit conditions, root systems may exhibit developmental plasticity resulting in morphological changes that extend the water-absorbing ...
Reflectance sensors to predict mid-season nitrogen need of cotton
(University of Missouri--Columbia, 2008)
Nitrogen (N) is an essential nutrient for cotton production; consequently there is a tendency to over-apply nitrogen. High N causes excessive vegetative growth and delayed crop maturity, which result in increased cost in ...
Allelopathic effects and removal of overseeded ryegrass on bermudagrass
(University of Missouri--Columbia, 2010)
Allelopathy is a complex phenomenon among plants that involves the production of defensive chemicals that influence the growth and survival of adjacent plants. Plants like perennial ryegrass become suspect when bermudagrass ...
Characterization of raffinose synthase genes in soybean
(University of Missouri--Columbia, 2009)
As the use of soy products in foods and feeds increases, it is ever more important to consider the nutritional value of each component of the seed. The carbohydrate component is largely composed of sucrose, raffinose, 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 ...
Influence of various factors, principally transpiration, upon infection of wheat and barley plants by the powdery mildew
(University of Missouri--Columbia, 1912)
Erysiphe Graminis is the powdery mildew which grows upon the Gramineae (Grass family). Something like fifty-five species of the family are affected by this fungus. Among these species are the cereals wheat, barley, oats, ...
