Viability, vigor, and field performance of a low phytic acid, high phytase activity soybean line, CAPPA
(University of Missouri--Columbia, 2009)
to lower the PA content of seeds may affect seed viability and seedling performance. This project was conducted in 2006 and 2007 to test the viability, vigor, and field performance of a high phytase activity, transgenic soybean line, CAPPA compared to its...
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 nodule that is able to fix...
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 by using carotenoid...
Poison hemlock (conium Maculatum L.) : biology, implications for pastures and response to herbicides
(University of Missouri--Columbia, 2008)
no dormancy restriction. Poison hemlock plants were actively growing in mid-March, and growth increased exponentially through mid-May. Biomass produced between mid-March and mid-May, considering all plant densities studied, range from 13 to 3,464 kg/ha. Most...
Molecular characterization of genetic resistance to soybean cyst nematode in soybean line SS97-6946
(University of Missouri--Columbia, 2008)
Soybean Cyst Nematode (SCN) (Heterodera glycine) is the most damaging pest of soybean and estimated annual yield losses are 1.5 billion dollars in USA. Breeding resistant cultivars is the most efficient means to control ...
Reflectance sensors to predict mid-season nitrogen need of cotton
(University of Missouri--Columbia, 2008)
with three sensors (Crop Circle, GreenSeeker, and Cropscan) at three growth stages (early square, mid square and early bloom) and at three heights above the cotton canopy (25, 50, and 100 cm) in 2006 and 2007. Results indicated that all three sensors have...
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 grazing stockpiled tall fescue of lactating beef cows
(University of Missouri--Columbia, 2006)
Two experiments are described, in which fall-calving cow-calf pairs grazed stockpiled tall fescue at three different endophyte infection levels (20, 51, and 89%) and four forage allowances (2.25, 3.00, 3.75, and 4.50% of ...
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 ...
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 ...
The balance between plant immunity and development: interactions of SRFR1 and TCP transcription factors
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Plants have developed a highly effective immune system for resisting microbial pathogens. One layer of the plant innate immune system is effector-triggered immunity. This immune...
Abscisic acid: interactions with ethylene and reactive oxygen species in the regulation of root growth under water deficit
(University of Missouri--Columbia, 2011)
Abscisic acid (ABA) is involved in several responses to plant water deficits, including an important role in root growth maintenance. Studies of the ABA-deficient maize mutant viviparous 14 (vp14) showed that ABA-deficiency ...
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 ...
Dissipation and carryover of imidazolinone herbicides in imidazolinone-resistant rice (Oryza sativa)
(University of Missouri--Columbia, 2007)
including flooded soils. Thirteen selected treatments of two and three sequential applications of imazethapyr and imazamox were applied to IR rice in 2004 and 2005. In 2005 and 2006, non-IR rice was planted into the previous years' plots to evaluate...
Reducing ergovaline and ergot alkaloid concentrations through fertilizer, herbicide and clipping management
(University of Missouri--Columbia, 2010)
rather than chemical NPK reduced ergovaline by at least 124 [mu] kg-1 DM. Another experiment showed the herbicide clethodim reduced ergovaline up to 72%. A third experiment, conducted with Clemson University and the University of Georgia, showed...
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 root depth and density, i...
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 ...
Characterization of raffinose synthase genes in soybean
