Genomic Characterization Of Necrotrophic Effector Sensitivity Genes In Wheat, Katherine Running Jan 2022

Genomic Characterization Of Necrotrophic Effector Sensitivity Genes In Wheat, Katherine Running

Genomics and Bioinformatics

The necrotrophic fungal pathogens Parastagonospora nodorum and Pyrenophora tritici-repentis cause the diseases septoria nodorum blotch (SNB) and tan spot, respectively, reducing yield by decreasing the photosynthetic area of the plant. The pathogens produce necrotrophic effectors (NEs) that target host genes to induce cell death. The Tsc1-Ptr ToxC and Tsn1-Ptr ToxA interactions contribute to plant susceptibility to tan spot, while the Tsn1-SnToxA and Snn5-B1-SnTox5 interactions contribute to SNB susceptibility. The three main goals of this dissertation were to clone susceptibility genes Tsc1 and Snn5 and develop robust genetic markers for use in marker-assisted elimination of Tsn1.

Health Nutrition and Exercise Science

During the US-Dakota War of 1862-1865, fighting and bloodshed targeted unarmed non-combatants on both sides. American memory has often fixated only on actions committed by Dakota peoples, Oceti Sakowin, that were deemed depraved. However, sane and level-headed US soldiers also killed and mutilated wounded warriors, as well as fired on women and children.

Commanders were able …

Using Electronic Handgrip Dynamometry To Determine Human Performance In Master's Aged Cyclists And Triathletes, Lukus Klawitter

Health Nutrition and Exercise Science

Purpose: This dissertation study sought to examine the correlations of maximal handgrip strength (HGS), rate of HGS force development, and HGS fatigability on lean body mass, peak power, functional threshold power, and aerobic capacity in master’s aged cyclists and triathletes. Methods: A cross-sectional design was utilized and the analytic sample included n=31 master’s aged cyclists and triathletes (age: 49.1±10.4 years). Achievement motivation was self-reported with a Situational Motivation Scale Questionnaire. A stationary bicycle trainer and metabolic cart was used to evaluate peak power and aerobic capacity with standardized protocols. Whole body bioelectrical impedance measured lean body mass. An electronic handgrip …
