Identifying Lepidopteran resistance within hcf mutants
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Southwestern corn borer (SWCB) and fall armyworm (FAW) feeding on maize causes extensive crop damage in the United States. Previous proteomic analysis comparing resistant and susceptible lines of maize indicates genes found ...
Quantitative trait loci for seminal root angle and number in the maize IBM population
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
In maize, seminal roots develop and the primary root system deteriorates as the plant matures. The seminal roots comprise the majority of the root system of the adult plant and give the plant stability against lodging. ...
Characterization of N gene homologs in Nicotiana species
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
We have developed a new variety of Nicotiana, N. edwardsonii var. Columbia, that can be used as a bridge plant to move virus resistance genes from N. glutinosa to N. clevelandii, and have made crosses between N. edwardsonii. ...
Development of conversation in toddlers: The role of maternal input
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
One of the most important human skills is the ability to engage in conversation. This includes our ability to initiate topics, take turns appropriately, and respond contingently to a partner's utterances. While we know ...
Mean value formulas for differential operators
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The main goal of our research is to discuss Mean Value Formulas for solutions of partial differential equations of a certain form (see 1 below) where A is a symmetric, positive definite, real-valued matrix. Such equations ...
The role of Periostin in regulating the biomechanical properties of cushion tissue
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
During embryonic heart development the atrio-ventricular (AV) cushions swell and fuse to form the valves and septa of the adult heart. Initially, the cushions appear as swellings on the interior wall of the AV canal and ...
Issues with scale using very high resolution digital aerial photographs
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
This study involves the use of remote sensing equipment to observe plant communities. A remote sensor is any instrument that gathers information about an object or area from a distance. Advanced cameras, the most common ...
Expression and purification of AlgX in Pseudomonas aeruginosa
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Pseudomonas aeruginosa is a Gram-negative bacterium that is the leading cause of hospital acquired infections. While this bacteria is present in water and soil, this bacteria only severely affects severely ill patients, ...
Characterizing polymerization dynamics using fluorescent molecular rotors and magnetoelastic sensors
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The dynamics of polymerization are critical in many medical applications; for instance, polymers used to fill aneurysms must be timed accurately. Two distinct methods were examined for their ability to probe the polymerization ...
Aβ toxicity to SHSY-5Y human neuroblastoma cells
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Alzheimer's disease (AD) is a progressive neurodegenerative disorder that results in the loss of memory, language deterioration, confusion, restlessness, and eventually destroyed cognition. It is characterized by an ...
Imaging reticulospinal neurons in the lamprey brainstem using calcium indicator
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Imaging reticulospinal neurons in the lamprey brainstem using calcium indicator In the lamprey, a lower vertebrate, reticulospinal (RS) neurons in the brain are the output elements of the command system that activate spinal ...
Analysis of mitochondrial DNA insertions into a nuclear chromosome of the maize B73 line
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Mitochondrial DNA (mtDNA) is known to have integrated into the nuclear DNA of plants and animals. The purpose of this project is to investigate the on-going migration of mtDNA into the nuclear DNA of maize plants. Specific ...
The effect of caloric restriction on the mitotic rates of mice
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Caloric restriction has been shown to cause a number of biological changes in animals including the retardation of the aging process. Calorically- restricted animals show an average increase in life span of 30 - 50 %. In ...
A search for regulators of a yeast synaptojanin
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The yeast S. cerevisiae expresses three synaptojanins: Inp51p, Inp52p, and Inp53p. These enzymes are characterized by two specific characteristics. They contain an inositol 5'-phosphatase and a polyphosphoinositide ...
The evolving technology of bio-printing
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Bio-printing is a novel method of tissue engineering that uses living cell spheroids as the 'bio-ink' and biocompatible gels as the 'bio-paper' with a three dimensional printer that deposits these aggregates into the gel ...
Effects of washings and treatments on the usefulness of hair as a biomarker
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Hair is a useful matrix for the analysis of many trace elements found in the human body. Studies show that hair can incorporate trace metals into its structure during the growth process. Hair is an attractive monitor because ...
Camgaroo-2 as an indicator of function in embryonic and neuralized stem cells
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The transplantation of stem cells to replace cells that have been lost or damaged due to disease or injury is quickly becoming a conceivable treatment method. Embryonic stem (ES) cells have the capacity to become any cell ...
Studying DNA methylation changes of CpG islands in different stages of prostate cancer by pyrosequencing
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Prostate cancer is one of the most common forms of cancer in men. Our lab is currently investigating changes in DNA methylation that occur during cancer progression, and in response to the soy phytoestrogen genistein ...
