Brassinosteroid-Mediated Stress Tolerance In Arabidopsis Thaliana, Tawhidur Rahman
Brassinosteroid-Mediated Stress Tolerance In Arabidopsis Thaliana, Tawhidur Rahman
Electronic Thesis and Dissertation Repository
Brassinosteroids (BRs) are a group of steroidal plant hormones that are essential for proper plant development and also promote stress tolerance. Without BRs, plants are dwarfs and infertile. To understand the molecular mechanisms underlying BR-mediated stress tolerance, global gene expression analysis of untreated and 24-epibrassinolide (EBR)-treated Arabidopsis thaliana seedlings under non-stress and heat stress (HS) conditions was carried out. Microarray data analysis indicated that stress-related genes were predominant within the EBR up-regulated gene data set. Furthermore, several of these genes were abscisic acid (ABA) and jasmonic acid (JA) related. Measurements of endogenous hormones showed significant increases in the levels ABA …
Gata-Family Transcription Factors In Magnaporthe Oryzae, Cristian F. Quispe
Gata-Family Transcription Factors In Magnaporthe Oryzae, Cristian F. Quispe
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
The filamentous fungus, Magnaporthe oryzae, responsible for blast rice disease, destroys around 10-30% of the rice crop annually. Infection begins when the specialized infection structure, the appressorium, generates enormous internal turgor pressure through the accumulation of glycerol. This turgor acts on a penetration peg emerging at the base of the cell, causing it to breach the leaf surface allowing its infection.
The enzyme trehalose-6- phosphate synthase (Tps1) is a central regulator of the transition from appressorium development to infectious hyphal growth. In the first chapter we show that initiation of rice blast disease requires a regulatory mechanism involving an …
Self-Assembled Rippling Structure Based On Metal-Elastomer Composite For Tunable Plasmonics, Fang-Tzu Chuang
Self-Assembled Rippling Structure Based On Metal-Elastomer Composite For Tunable Plasmonics, Fang-Tzu Chuang
Fang-Tzu Chuang
We demonstrate that a periodic metallic wavy-structure can be easily fabricated on elastomeric polydymethylsiloxane (PDMS) substrates. The metallic wavy-structures are self-assembly formed by thermal evaporation of Ag on PDMS without any lithography processes. The size of the PDMS substrate with an aspect ratio (the ratio of length to width) higher than 2 are found to be necessary to self-assemble the one-dimensional metallic wavy-structure. The period of the wavy-structure is controllable by varing the thickness of the deposited silver film. The elastomeric- gratings can excite surface plasmon on Ag/air interfaces; the resonant wavelength can be tuned to a range of 3.5% …
Science Boot Camp For Librarians: Cpd On A Shoestring, Maxine G. Schmidt, Rebecca Reznik-Zellen
Science Boot Camp For Librarians: Cpd On A Shoestring, Maxine G. Schmidt, Rebecca Reznik-Zellen
Maxine G Schmidt
Science Boot Camp for Librarians was envisioned as a casual but intensive immersion event into selected scientific subjects that employ networked computing capabilities for research and collaboration. The goal of the event is to provide librarians with networking opportunities, but more importantly, to give them some of the context and ocabulary of a discipline to enable them to better engage faculty and research scientists with regard to escience. A half-day is devoted to each of three topics chosen for that year’s camp. A local faculty member provides an overview of the research area, and a second describes a single project …
Muc4 Modulation Of Ligand-Independent Erbb2 Signaling, Goldi Attias Kozloski
Muc4 Modulation Of Ligand-Independent Erbb2 Signaling, Goldi Attias Kozloski
Goldi A Kozloski
The membrane mucin Muc4 is a heterodimer, bi-functional glycoprotein complex that is normally expressed in epithelial tissue. Functional studies on the extracellular mucin subunit of Muc4 have shown that it acts to promote anti-adhesion properties by sterically interfering with cell-cell and cell-matrix interactions and that the extent of this effect is directly associated with the number of tandem repeats on this subunit. Functional studies on the transmembrane subunit of Muc4 have shown that this subunit participates in intracellular signaling through interaction with the receptor tyrosine kinase ErbB2. This role of Muc4 was shown to be mediated by stabilizing the heregulin …
Localized Shape Resonance On Silver Film Perforated By H-Shaped And More Complex Shaped Hole Arrays, Fang-Tzu Chuang
Localized Shape Resonance On Silver Film Perforated By H-Shaped And More Complex Shaped Hole Arrays, Fang-Tzu Chuang
Fang-Tzu Chuang
The experimental results of light transmission through periodic array of H-shaped hole and more complicated hole which is a combination of multiple U shape are demonstrated. The observations indicate that the localized shape resonance in the longest resonant length of unfolded U-shaped part of the hole always appears. However, localized modes resonant in smaller U-shaped length don't always appear. Localized mode with non-U-shaped resonant path cannot be seen in our sample. In addition, localized mode with different order and resonant path can be excited by different polarized light.
Science For The Environment: Examining The Allocation Of The Burden Of Uncertainty, Elisa Vecchione
Science For The Environment: Examining The Allocation Of The Burden Of Uncertainty, Elisa Vecchione
Elisa Vecchione
The aim of this paper is to review the basic literature on scientific uncertainty in its statistical paradigm in order to provide enlightenment on one pivotal facet of the precautionary principle, i.e. the allocation of the burden of proof to demonstrate that an activity is not harmful to the environment. The purpose is not to explain a new theory of statistical inference, but to show how regulatory policymaking that is properly informed by scientific expertise and designed to avoid one type of error, may actually make other errors more likely and thus expose the public to danger. This problem is …

El objetivo de la ganadería bovina es el de la maximización de la producción, entendido como la cantidad máxima de carne o leche que debe producir un bovino para que sea económicamente sustentable. En este afán por subsistir en la competitividad del mercado y en la globalización del mismo, las estrategias alimenticias constituyen quizás la manera más sencilla para mejorar las condiciones productivas de los animales. En lechería especializada tanto los parámetros reproductivos como la incidencia de mastitis en el hato son elementos vitales para asegurar una participación amplia en el mercado. En 1996 se estimó que el costo calculado …

Role Of Vascular Endothelial Growth Factor, Placental Growth Factor And Cytokines On Outer Blood Retinal Barrier Breakdown., Sangeetha Sukumaran
Masters
The aim of this thesis was to investigate the effect of the VEGF family of growth factors and
cytokines TNF- α and IL-1β on oBRB function. The human RPE line ARPE-19 was
employed as an in vitro model of the oBRB. Two-Dimensional gel electrophoresis was
employed to study the effect of growth factors on the RPE proteome. The barrier properties of
the oBRB were evaluated by expression of the TJ proteins occludin or Zo-1, or claudins-1, 2,
3 and 4, determined by western blotting analysis. Claudins 2, 3 and 4 were found to be
significantly up-regulated by TNF-α, while interleukin …

Anesthesia plays a vital role in the maintenance of aquaculture species, where it is used to minimize stress during complex handling tasks such as transport, assessment, and harvesting. However, anesthetics have been shown to suppress the innate immune response, which could impact immunity and increase risk of infection. Tricaine methanesulfonate (MS-222) and 2-Phenoxyethanol (2-PE) represent two of the most commonly used anesthetics in aquaculture, with R-(+)-carvone, in the form of carvone-methyl salicylate (CMS) has recently been proposed as an alternative anesthetic for food fish. These three anesthetics were used to assess the influence of anesthetics on the immune system of …
