In order to see the correlation between stem rust resistance and tan spot susceptibility in 1970’s, to know the pathogen virulence profile, and explore the sources of tan spot resistance, we recovered isolates from wheat and rye and evaluated wheat and rye lines with …


Silencing Seed Dormancy Genes To Mitigate Risk Of Transgene Flow To Weedy Rice, Alexander Wireko Kena Jan 2017

Silencing Seed Dormancy Genes To Mitigate Risk Of Transgene Flow To Weedy Rice, Alexander Wireko Kena

Electronic Theses and Dissertations

The flow of fitness-enhancing transgenes from genetically modified crops into wild/weed relatives may cause serious ecological and economic consequences. Seed dormancy (SD) is a key adaptive trait that distributes germination over time, resulting in weed persistence in agroecosystems. Thus, silencing major genes controlling SD would reduce the adaptive fitness of weeds. SD-enhancing genes cloned from weedy rice include SD7-1, SD7-2, SD12a, SD12b, and SD12c. The goal of this study was to develop a transgenic mitigation (TM) strategy using SD gene-silencing structures as mitigating factors to reduce the risk of transgene flow to wild/weed populations. TM vector constructs consisted of the …

Elucidation Of Abscisic Acid In Stress Resistance Of Mnium Cuspidatum Through Salt Exposure And Chlorophyll Content Analysis, Kurt Corsbie

Undergraduate Honors Thesis Collection

Upon exposure to stresses, a battery of reactions occurs within the model moss Physcomitrella patens that induces the expression of defense-related genes. One of these reactions results in the production of abscisic acid (ABA), a plant hormone that helps a plant resist desiccation by inducing the activation of defense genes which results in protective physiological reactions. In this study, experiments were conducted on the moss species Mnium cuspidatum to see if it responds similarly to P. patens. This comparison was investigated as sample groups of M. cuspidatum and P. patens were pre-treated with 0µM, 50µM, or 500µM ABA to …

Dreadlocks (Dock) Is Necessary To Regulate Growth Of The Germline Ring Canals In The Developing Drosophila Melanogaster Egg Chamber, Olivia Crowe

Undergraduate Honors Thesis Collection

Infertility is a prevalent issue in the United States, impacting 1.5 million women (1). A possible cause of infertility is defects in gametogenesis, or the formation of sperm and egg. Therefore, understanding the basic mechanisms that promote normal gamete formation could impact our understanding of infertility. The Drosophila melanogaster egg develops from an organ-like structure called an egg chamber. The egg chamber is composed of a central cluster of 16 germ cells that are connected to one another by intercellular bridges, called ring canals. These ring canals are composed of filamentous actin and allow the transfer of materials from supporting …

The Media And Teenage Violence: How Much Is Too Much When It Comes To Adolescent Aggression?, Taylor Pearson

Undergraduate Honors Thesis Collection

With the advent of increasingly accessible technology and the growing prevalence of both fictional and nonfictional violence in the media (American Academy of Pediatrics 2009; American Psychological Association 2013; Emmons 2013; Pew Research Center 2015), the effects of such content on emotional states and behavioral patterns in youths has garnered a great deal of interest among sociologists, psychologists, and developmental experts. However, the results of existing research are inconclusive and often contradictory (APA 2013; Siegel and Welsh 2017:86-87), providing no clear answer to the question of whether or not this content actually affects viewer behavior. I explore the current body …


The Social Construction Of Winston Churchill: How Life Experiences Shaped The Identity Of A Wartime Legend, Molly Elisabeth Smith Jan 2017

The Social Construction Of Winston Churchill: How Life Experiences Shaped The Identity Of A Wartime Legend, Molly Elisabeth Smith

Undergraduate Honors Thesis Collection

While the theory of social constructivism in international relations may not be the most common, it has appeared in different forms throughout the twentieth century and has gained popularity in recent years. Focusing on the formation of - and potential for change in - identities and interests, constructivism allows for the consideration of both ideational and behavioral factors in studying actors of the international community. Pairing these concepts with principles from both social identity theory and political psychology, one can observe the constructivist development of identities and interests of a political individual, such as Winston Churchill. Churchill's unique life experience …


The Back Pocket Play: Revealing White Privilege And Its Contribution To Institutionalized Racism, Sonia Michelle Goldberg Jan 2017

The Back Pocket Play: Revealing White Privilege And Its Contribution To Institutionalized Racism, Sonia Michelle Goldberg

Undergraduate Honors Thesis Collection

Black lives matter. This phrase incites intense and polarizing emotions in our community: with it brings images of police brutality. It forces the topic of racism to the forefront of the listener’s mind. And when that listener hardly ever considers issues of race in their daily life, “Black lives matter” easily becomes a hostile phrase, one to shrink away from. Why? This ability to dissociate – to write off uncomfortable situations – is a privilege. In predominately White communities like Butler University, individuals are often hesitant to have a conversation about race, because they believe firmly it is not their …


Regulating Milk: Women And Cows In France, Mathilde Cohen Jan 2017

Regulating Milk: Women And Cows In France, Mathilde Cohen

Faculty Articles and Papers

Animal milk, most commonly cow’s milk, is one of the most heavily regulated commodities in both France and the United States. With the increasing popularity of breastfeeding and the possibility of pumping, freezing, and storing breast milk, a cottage industry has emerged for people wishing to buy, sell, or donate milk produced by humans. Yet the legal landscape for human milk remains inchoate, prompting public health officials and medical professionals to call for tighter regulation. Animal and human milk are typically viewed as two distinct substances with little in common beyond a name. In contrast, this Article highlights the analogies …
