A genotypic comparison of plasticity of root system development during soil drying in soybean (Glycine max (L.) merrill)
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Water deficit is responsible for significant losses in soybean (Glycine max (L.) Merrill) yield under dryland conditions. Under drought, increases in ...
Agronomic and pest interactions in no-till corn and soybean wih fall versus spring herbicide applications
(University of Missouri--Columbia, 2006)
Fall herbicide applications have increased in popularity in recent years. Little is known of how fall herbicide applications impact soil conditions, insect populations, and winter and summer annual weed populations. Few ...
Sulfur metabolism in Glycine max [L.] Merr : characterization of serine acetyletransferase and O-acetylserine (thiol) lyase
(University of Missouri--Columbia, 2006)
Soybean (Glycine max [L.] Merr) is considered an excellent protein source for both humans and livestock. Further improvement of quantity and quality of soybean protein is vital for maintaining the utility of this versatile ...
The effect of environment on seed composition of tofu and natto soybean cultivars
(University of Missouri--Columbia, 2006)
Composition of soybean seeds is important to manufacturers of tofu and natto food products. The effect of environment on seed composition of tofu and natto soybean cultivars was measured in Missouri in 2004 and 2005. The ...
Function of abscisic acid in maintenance of maize primary root growth under water deficit
(University of Missouri--Columbia, 2006)
Previous studies suggested that ABA accumulation is required to maintain maize primary root elongation under water deficit and that one of the functions of ABA is to restrict ethylene evolution. These studies were conducted ...
Management alternatives for urea use in corn and wheat production
(University of Missouri--Columbia, 2006)
Traditionally, urea has been incorporated to avoid losses of N by ammonia volatilization. However, this option is not available when topdressing wheat. The objective of this project is to evaluate several strategies designed ...
Functional analysis of drought responsive soybean GmNAC003 and GmNAC004 transcription factors in lateral root development in arabidopsis
(University of Missouri--Columbia, 2011)
Several NAC transcription factors promote lateral root (LR) numbers in Arabidopsis through the auxin signaling pathway. In soybean, a majority of genotypes increased LR number in response to water deficit. It is possible ...
Manganese nutrition and photosynthesis in NAD-malic enzyme C-4 plants
(University of Missouri--Columbia, 2008)
Based on their photosynthetic pathways, plants can be divided into three major groups: C-3, CAM, and C-4. In C-4 plants, the release of CO2 for Calvin cycle reactions in bundle sheath cells (BSC) involves one of the three ...
Weed management and nitrogen loss in glyphosate-resistant corn (Zea mays)
(University of Missouri--Columbia, 2009)
The advent of glyphosate-resistant corn in Missouri has changed traditional reemergence (PRE) followed by postemeregence (POST) herbicide programs to ones that predominately utilize glyphosate POST. POST only programs can ...
Physiological traits underlying differences in salt tolerance among glycine species
(University of Missouri--Columbia, 2008)
Salinity drastically reduces crop yield by limiting water uptake and causing ion-specific stress. Soybean is sensitive to soil salinity. Previous studies, however, have shown that there is variability among soybean genotypes ...
The role of genetic and phenotypic diversity in maize and its effects on aflatoxin accumulation by the fungus Aspergillus flavus
(University of Missouri--Columbia, 2008)
Accumulation of the potent carcinogen, aflatoxin, in maize poses a significant health risk to humans and animals. Most commercially grown maize lines are susceptible to infection by the fungus that synthesizes aflatoxin, ...
Recommendations for tree establishment in tall fescue-based silvopasture
(University of Missouri--Columbia, 2008)
Silvopasture offers Midwest landowners the opportunity to plant trees in their pastures without significant loss of forage production. However, much of the pasture in the Midwest is dominated by tall fescue (Schedonorus ...
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 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 ...
Molecular cloning and characterization of regulatory enzymes in threonine biosynthetic pathway from soybean
(University of Missouri--Columbia, 2007)
Soybeans (Glycine max [L.] Merr.) are a good source of protein and oil. Despite being a very good source of protein, soybeans nutritional value is limited by low proportion of sulfur amino acids methionine and cysteine ...
Impact of aphids species and barley yellow dwarf virus on soft red winter wheat
(University of Missouri--Columbia, 2005)
Barley yellow dwarf virus is one of the most widespread viral diseases of wheat. Yield reductions up to 70% have resulted from barley yellow dwarf virus (BYDV) infection. Several aphid spp. transmit BYDV. In Missouri, the ...
Overseeding annual ryegrass and cereal rye into soybean for winter forage and as a cover crop for weed control and soil conservation
(University of Missouri--Columbia, 2005)
Annual ryegrass (Lolium multiflorum Lam.) and cereal rye (Secale cereale L.) are two forages that fit well into mixed row crop/livestock operations as they can be used both as a cover crop and as a source of winter pasture. ...
Soybean seed components as affected by nodal position, environmental conditions, and irrigation
(University of Missouri--Columbia, 2005)
Soybeans (Glycine max [L.] Merr.) are a major source of vegetable protein and edible oil. The nutritional quality of these seed components depends upon the relative abundance of specific proteins and fatty acids. Additionally, ...
