Development Of A Novel Aluminum Tolerance Phenotyping Platform Used For Comparisons Of Cereal Aluminum Tolerance And Investigations Into Rice Aluminum Tolerance Mechanisms, Adam N. Famoso, Randy T. Clark, Jon E. Shaff, Eric Craft, Susan R. Mccouch, Leon V. Kochian
Faculty Publications
The genetic and physiological mechanisms of aluminum (Al) tolerance have been well studied in certain cereal crops, and Al tolerance genes have been identified in sorghum (Sorghum bicolor) and wheat (Triticum aestivum). Rice (Oryza sativa) has been reported to be highly Al tolerant; however, a direct comparison of rice and other cereals has not been reported, and the mechanisms of rice Al tolerance are poorly understood. To facilitate Al tolerance phenotyping in rice, a high-throughput imaging system and root quantification computer program was developed, permitting quantification of the entire root system, rather than just the longest root. Additionally, a novel …

The depletion of petroleum reserves, rising and extremely volatile crude oil prices, and environmental concerns have led to search for renewable and environmentally friendly fuels. The ultimate goal of this research was to develop, test and optimize a batch microwave system using traditional and alternate non-food feedstocks. Microwave assisted extraction (MAE) of oil from conventional feedstocks (soybeans and rice bran) and an alternative feedstock (Chinese tallow tree (CTT) seeds) was carried out. The study concluded that MAE of oil is …
Adolescents' Expectancy Beliefs And Task Values For Physically Interactive Video Games, Andrew James Mcgregor
Adolescents' Expectancy Beliefs And Task Values For Physically Interactive Video Games, Andrew James Mcgregor
LSU Master's Theses
The health benefits associated with appropriate levels of physical activity are well documented, but a large percentage of the population is not sufficiently active to attain those health benefits. Children are also not as active as they should be, and their activity levels decline during adolescence. Given that childhood activity patterns are likely to persist into adulthood, it is important to investigate ways to encourage children and adolescents to be physically active. Since virtually all school students participate in physical education programs, one way to do that is to explore ways that physical education programs can motivate children to be …

Investigating The Use Of Bioengineered Oyster Reefs As A Method Of Shoreline Protection And Carbon Storage, Daniel D. Dehon
LSU Master's Theses
The Louisiana Gulf Coast is losing land at an alarming rate for a combination of reasons. At the same time carbon dioxide is accumulating in the atmosphere and the oceans by the increased burning of fossil fuels. Therefore, bioengineered oyster dominated artificial reefs have been developed in an effort to mitigate erosion while storing carbon in the oyster shells. These reefs support the growth of a native oyster species, Crassostrea virginica, which are considered ecological engineers and serve to improve water quality, protect coastal wetlands, capture and store carbon, and enhance the economy. Evaluation of test pieces showed the addition …

A Study Of Passalid Beetle Prokaryote And Yeast Gut Symbionts, Stephanie Rachelle Gross
LSU Master's Theses
Scheffersomyces stipitis (=Pichia stipitis) is a xylose-fermenting and assimilating yeast (Ascomycota: Saccharomycotina) consistently isolated from the gut of Odontotaenius disjunctus (Coleoptera: Passalidae). This filamentous yeast is often attached to the wall of the posterior hindgut of the beetle by a holdfast. Gallery walls of white-rotted wood inhabited by the beetle are lined with macerated wood and frass that includes the yeast and other microbes. Previous studies have mentioned the relationship between the passalid and this yeast; however, passalid beetles also harbor a community of prokaryotes in their guts that have not been characterized. Experiments using culturing and cloning techniques and …

Developing Tools To Identify Factors That Limit Production In Coastal Marshes, Vanessa Danielle Tobias
Developing Tools To Identify Factors That Limit Production In Coastal Marshes, Vanessa Danielle Tobias
LSU Doctoral Dissertations
Marsh loss is a problem in many areas around the world. In Louisiana’s coastal marshes, where Spartina patens is the most common plant, restoration and management seek to slow wetland loss rates that average approximately 77.4 km2/year. To combat the problem, scientists and managers require tools to determine local causes and evaluate the effectiveness of management techniques. Current methods for identifying factors that limit productivity in marshes are too time-consuming or expensive for wide-spread, regular use. Critical values of elemental concentrations in plant tissue are widely used to diagnose mineral deficiencies and toxicities in agricultural crops, however. I used the …

Effects Of Environmental Variables And Crop Growth On Development Of Brown Rust Epidemics In Sugarcane, Wilmer Anibal Barrera
Effects Of Environmental Variables And Crop Growth On Development Of Brown Rust Epidemics In Sugarcane, Wilmer Anibal Barrera
LSU Master's Theses
Natural epidemics of brown rust, caused by Puccinia melanocephala, affecting sugarcane were studied to determine the crop and/or environmental factors that affect epidemic onset, severity and eventual decline. Environmental and crop growth variables were monitored along with disease severity in two susceptible cultivars, LCP 85-384 and Ho 95-988, each grown at a different location in Louisiana. During two seasons, correlation and multiple regression analyses identified leaf wetness and temperature as important determinants of disease severity for both cultivars. The results suggested that crop growth variables were not determinants for epidemics. Controlled conditions experiments assessing the interaction of leaf wetness and …

Effects Of Emulsion Coatings On The Internal Quality And Shelf Life Of Eggs, Damir Dennis Torrico
LSU Master's Theses
Mineral oil (MO) is currently used for coating eggs to preserve quality. Chitosan possesses inherent antimicrobial and film-forming properties. Chitosan coating (CH) is dried much faster than MO when applied on egg shell. Information on synergistic effects of MO:CH emulsion coatings on egg quality does not exist. We developed MO:CH emulsion coatings, and evaluated their effects on internal quality and shelf-life of eggs during storage. In the first study, MO, CH and three emulsions (MO:CH = 75:25, 50:50, and 25:75) were evaluated during 5 weeks at 25°C. Haugh unit (HU) and yolk index values decreased whereas weight loss increased during …
Ancestral Determination From Foramen Magnum, Stephanie Marie Crider
Ancestral Determination From Foramen Magnum, Stephanie Marie Crider
LSU Master's Theses
Ancestry estimation is a crucial part of the biological profile creation in forensic anthropology. Without proper classification of ancestry, other aspects of the biological profile, such as stature, can be affected. Several techniques are used by forensic anthropologists to determine ancestry of unidentified remains. Some anthropologists believe the cranium to be an excellent indicator of ancestry (Rhine 1990). The focus of this research was to determine the utility of the foramen magnum region on the cranial base as a positive indicator of ancestry. Previous studies have explored the effectiveness of using the cranial base’s occipital condyles for ancestry assignment of …
Role Of Gastrointestinal Multidrug Resistance (Mdr1) Gene And P-Glycoprotein (P-Gp) In The Oral Absorption Of Methadone In Horses, Renata Lehn Linardi
Role Of Gastrointestinal Multidrug Resistance (Mdr1) Gene And P-Glycoprotein (P-Gp) In The Oral Absorption Of Methadone In Horses, Renata Lehn Linardi
LSU Doctoral Dissertations
Methadone is a mu-opioid receptor agonist which is a very effective analgesic used to treat moderate to severe acute and chronic pain in humans. Due to methadone’s minimal undesirable side-effects in people, we believed it could be of use in horses as an analgesic agent. As found with the majority of lipophilic drugs, absorption of methadone occurs primarily in the small intestine via transcellular transport and its absorption is regulated by P-glycoprotein. P-glycoprotein is a transmembrane transporter protein encoded by the multidrug resistance gene, which is constitutively expressed in the apical membrane of enterocytes of various species. This protein may …

LSU Doctoral Dissertations
This study examined African American (AA) caregivers’ beliefs about their children’s language-literacy development and their book reading behaviors with their children as a function of socioeconomic status (SES). Caregivers’ behaviors were examined before, during, and after a three-day caregiver training program that targeted four behaviors (i.e., tracking print, reference to print, text to life, and interpretations). Participants were 20 caregiver-child dyads classified as Low-SES (LSES) or Middle-SES (MSES) based on the caregivers’ level of education. Children were typically developing girls between the ages of four and five years. At pre-test, the two groups of caregivers differed in some of their …
A High Fat Diet Attenuates The Fermentation Effects Of Resistant Starches And Fructans, Felicia Robin Goldsmith
A High Fat Diet Attenuates The Fermentation Effects Of Resistant Starches And Fructans, Felicia Robin Goldsmith
LSU Master's Theses
In our previous studies, ingestion of prebiotics in low fat diets resulted in decreased cecal pH from 8 to about 6 and increases in short chain fatty acids indicating robust fermentation. However, in some preliminary studies this effect on fermentation was not seen when rodents were obese and/or fed a high-fat diet. This comprehensive high-fat diet study was conducted to determine which sources and combinations of prebiotics would enhance fermentation despite a high dietary fat content. The effects of prebiotics in a high-fat diet (44% energy) on pH, cecal weights, abdominal fat, and body weight were studied in mature male …

The Influence Of Two Estrogens On The Sex And Ovarian Development Of Eastern Oysters (Crassostrea Virginica) Maintained In A Closed Recirculating System, Wesley Michael Burnside
LSU Master's Theses
As a multi-million dollar industry, production of the eastern oyster Crassostrea virginica is significant to the economy of the nation’s coastal regions. The cost of commercial oyster aquaculture has higher inputs than the oyster fishery, but larger, better quality oysters can be produced for culture by the stable availability of triploid individuals.
The goal of this project was to determine if the use of an estrogen, estradiol-17β or estradiol-3-benzoate, at a consistent environmental temperature would increase the percentage of females in a population, as well as ovarian development of eastern oysters. Ultimately, this could be applied to triploids to increase …

The Returns And Volatility Of Agribusiness Stocks: How Do They Measure Up To Non-Agribusiness Stocks?, Benjamin Michael Clark
LSU Master's Theses
Little literature exists that analyzes the historical risk and return associated with investing in the US agricultural sector. However, several observable trends have recently made investing in the US agricultural sector an area of interest among investors. Stock price indexes are a commonly used tool for summarizing the historical performance of a specific sector. A market-capitalization weighted stock price index is created to represent the largest US agribusiness firms since 1970, using the US Census Standard Industrial Classification system and the Economic Research Service’s definition of agribusiness. Geometric returns, standard deviation, Sharpe Ratio, and beta values are calculated for one, …
Effect Of Resistant Starch On Microbial Content Of The Intestinal Tract, Reshani Nisansala Senevirathne
Effect Of Resistant Starch On Microbial Content Of The Intestinal Tract, Reshani Nisansala Senevirathne
LSU Doctoral Dissertations
Resistant starch (RS) increases beneficial gastro-intestinal bacterial populations simultaneously increasing short-chain fatty acids (SCFA) such as butyrate. Butyrate acts as energy source for epithelial cells of colonic mucosa which stimulates intestinal cell proliferation and has been implicated as important in reducing obesity, diabetes and cancer. The Lactobacillus spp, Bifidobacterium spp, Bacteroides thetaiotaomicron, Clostridium cluster IV and Clostridium cluster XIV are mainly involved in the production of butyrate by fermenting RS in the large intestine. With age there is a decline in these gut bacteria, but in the present study RS and diet restriction both enhanced the bacteria involved in butyrate …
