Using Genomic And Gene Expression Methods To Understand The Phenotypic Response Of Soybean To Sudden Death Syndrome Caused By Fusarium Virguliforme, Alexander Stephen Luckew Jan 2018

Using Genomic And Gene Expression Methods To Understand The Phenotypic Response Of Soybean To Sudden Death Syndrome Caused By Fusarium Virguliforme, Alexander Stephen Luckew

Graduate Theses and Dissertations

Soybean sudden death syndrome (SDS) is one of the most important soybean diseases in the Midwestern United States, leading to average losses of $396 million per year from 1996 to 2015. The causal agent of SDS, soilborne fungus Fusarium virguliforme (Fv), causes root rot symptoms and releases phytotoxins taken up by the plant to produce chlorosis and necrosis in the leaves. The main management practice used to reduce the impact of SDS is planting resistant soybean cultivars. Resistance to SDS is known to be quantitative with 88 known quantitative trait loci (QTL) based on Soybase.org. Many of these QTL ...


Molecular Mechanisms Governing Plant Parasitic Nematode Signaling And Host Parasitism, Stacey Nicola Barnes Jan 2018

Molecular Mechanisms Governing Plant Parasitic Nematode Signaling And Host Parasitism, Stacey Nicola Barnes

Graduate Theses and Dissertations

Pathogen infection of crops causes large-scale annual yield losses for farmers worldwide and hinders global efforts to provide adequate amounts of nutrition for the ever-growing human population. Plant-parasitic nematodes (PPN) are among some of the most devastating pathogens due to their ability to parasitize an expansive variety of agriculturally important crops. In order to identify ways to attenuate PPN infection and limit yield losses it is vital that we increase our understanding of host-PPN interactions. Here we investigate the molecular mechanisms that are occurring both within PPN and at the interface between PPN and their host plants.

Research into PPN-derived ...


Investigating The Interplay Of Physiological And Molecular Mechanisms Underpinning Programmable Aspects Of Heat Stress In Pigs, Jacob Seibert Jan 2018

Investigating The Interplay Of Physiological And Molecular Mechanisms Underpinning Programmable Aspects Of Heat Stress In Pigs, Jacob Seibert

Graduate Theses and Dissertations

Heat stress (HS) undermines production efficiency in all animal agriculture, culminating in major economic losses annually. The effects of HS in pigs is realized through depressed growth, altered body composition, and impaired reproductive performance. Pigs, unlike other mammals, do not possess functional sweat glands, making them rely on other mechanisms to thermoregulate during a heat challenge. Continual investigation of hyperthermia in pigs is crucial for developing new strategies and/or technologies that mitigate the effects of HS imposed on the pork industry. The studies conducted in this dissertation investigate the complex interplay of whole-animal physiology as well as cellular and ...
