Has Maize Overtaken Our Reality? A Personal Briefing, Biochemical Comparison, Agrigenomics, And History Of Maize, Nader Pahlevan May 2021

Has Maize Overtaken Our Reality? A Personal Briefing, Biochemical Comparison, Agrigenomics, And History Of Maize, Nader Pahlevan

Honors Theses

Maize (Zea mays ssp. Mays) is a revolutionary cereal grain that has raced to the world’s most popular staple crop, transforming societies and impacting history. This paper aims to build and portray the story maize has created through its journey to world domination. The important details that encompass this literature are maize’s cultural significance in my life’s story, the comparison of various starches broken down into amylose and amylopectin ratios, a summative historical account on maize’s spread throughout numerous parts of the old world, and the genetical analysis of maize that explains the key features that have led …


Examining The Role Of The Drosophila Melanogaster Unc13 Protein In Open Field Activity Using Rnai, Islam Orabi May 2021

Examining The Role Of The Drosophila Melanogaster Unc13 Protein In Open Field Activity Using Rnai, Islam Orabi

Honors Theses

Unc13 are proteins in the presynaptic neurons essential in controlling synaptic vesicle fusion and synaptic transmission. Recently, the reduction of Drosophila melanogaster Unc13 proteins (Dunc13), were found to result in a resistance to alcohol, highly reminiscent of tolerance formation. I investigated whether genetically reducing Dunc13 activity in Drosophila brain regions leads to different forms of behavioral plasticity using an open field activity paradigm. In my approach, a Dunc13 RNAi transgene was expressed in the Drosophila brain within the mushroom body, the ellipsoid body, and in all neurons. The activities of the flies were examined in the open field paradigm to …


The Biodiversity Of Deadwood-Associated Arthropods In The Southern Appalachian Mountains, Isabelle Ong May 2021

The Biodiversity Of Deadwood-Associated Arthropods In The Southern Appalachian Mountains, Isabelle Ong

Honors Theses

A biodiversity hotspot is a location that has significantly elevated levels of biodiversity including many species found nowhere else, and which is also in danger of losing much of this diversity. By identifying biodiverse regions, conservation efforts can be targeted to those locations where they are likely to have the most beneficial impacts. We looked at deadwood associated arthropods within the Southern Appalachian Mountains to examine centers of biodiversity. Nine logs were sampled, three of which were located in Bankhead National Forest and six were located in the Great Smoky Mountains. Polymerase chain reaction was used to amplify the mitochondrial …


Association Of Trim Gene Variation And Lpdv Infection Patterns In Wild Turkeys, Bennett Fry Apr 2021

Association Of Trim Gene Variation And Lpdv Infection Patterns In Wild Turkeys, Bennett Fry

Honors Theses

Emerging infectious diseases pose a serious threat to various species throughout the globe, including humans. The lymphoproliferative disease virus (LPDV) in wild turkeys is an example of disease virus whose impact on its host requires additional study. Although the first description of lymphoproliferative disease came from outbreaks in domestic turkey flocks in Europe, it is now known that LPDV is widespread in wild turkey populations in North America. In an effort to understand what may affect an individual turkey’s susceptibility to this virus, variation in part of the anti-viral TRIM62 gene was investigated. DNA was extracted from hunter-collected, turkey blood …
