Chromosome-Scale Assemblies And A Pangenome Reveal Ltr Repeat Dynamics As A Major Driver Of Genome Evolution In Chenopodium, Kate E. Jaggi Jun 2024

Chromosome-Scale Assemblies And A Pangenome Reveal Ltr Repeat Dynamics As A Major Driver Of Genome Evolution In Chenopodium, Kate E. Jaggi

Theses and Dissertations

The genus Chenopodium, which comprises around 150 species globally, is characterized by its wide geographic distribution and ecological adaptability, particularly in temperate regions. Some species, such as Chenopodium quinoa and Chenopodium pallidicaule, have served as domesticated staple crops in the Andean region of South America for centuries, valued for their robust nutritional profile and adaptability to adverse environmental conditions. In contrast, wild Chenopodium species exhibit broad geographic distributions and diverse niche adaptations, functioning as reservoirs for beneficial traits, including disease resistance and climate hardiness, essential for enhancing domesticated crops through introgression and breeding efforts. However, taxonomic classification within the genus …

Mitigating Toxic Metal Exposure Through Leafy Greens: A Comprehensive Review Contrasting Cadmium And Lead In Spinach, Angelia L. Seyfferth, Matthew A. Limmer, Benjamin R. Runkle, Rufus L. Chaney

Biological Sciences Faculty Publications and Presentations

Metals and metalloids (hereafter, metal(loid)s) in plant-based foods are a source of exposure to humans, but not all metal(loid)-food interactions are the same. Differences exist between metal(loid)s in terms of their behavior in soils and in how they are taken up by plants and stored in the edible plant tissue/food. Thus, there cannot be one consistent solution to reducing toxic metal(loid)s exposure to humans from foods. In addition, how metal(loid)s are absorbed, distributed, metabolized, and excreted by the human body differs based on both the metal(loid), other elements and nutrients in the food, and the nutritional status of the human. …


Removal As A Control Method For Trachemys Scripta Elegans And The Response Of Chrysemys Picta Bellii, Jacob Swanson Jun 2024

Removal As A Control Method For Trachemys Scripta Elegans And The Response Of Chrysemys Picta Bellii, Jacob Swanson

University Honors Theses

The red-eared slider is considered one of the most ubiquitous freshwater turtles globally. Several key ecological advantages and life history traits of this species jointly impact growth rates and survivorship of native freshwater turtles where sympatry occurs. Evaluation of current management actions for red-eared slider turtles is limited, resulting in a paucity of information to guide management for the species and conservation of declining native freshwater turtles. We used previously collected mark-recapture and removal sampling data from sites with sympatric populations of red-eared slider and western painted turtles. We examined the effects of control (trapping and removal) of red-eared sliders …


The Effects Of Wildfire Burn Severity On Bee And Wasp Communities Two Decades Post-Fire, Alaina K. Smith Jun 2024

The Effects Of Wildfire Burn Severity On Bee And Wasp Communities Two Decades Post-Fire, Alaina K. Smith

Electronic Theses and Dissertations

While fire is a natural disturbance in many global ecosystems, anthropogenic changes are affecting fire frequency, severity, and seasonality. Disturbances like wildfire affect bee and wasp communities, but recent meta-analyses are conflicted about whether fire harms or benefits insect pollinators. We investigated the lasting effects of wildfire burn severity on wild bee communities and floral resource availability across different burn severities in two-mixed severity fires that burned >20 years ago. We found that high severity fire has positive effects on bee diversity that are associated with severity-mediated changes to the floral community. We also studied the effects of wildfire burn …

Department of Animal Science: Faculty Publications

Introduction: Pubertal attainment is critical to reproductive longevity in heifers. Previously, four heifer pubertal classifications were identified according to attainment of blood plasma progesterone concentrations > 1 ng/ml: 1) Early; 2) Typical; 3) Start-Stop; and 4) Non-Cycling. Early and Typical heifers initiated and maintained cyclicity, Start-Stop started and then stopped cyclicity and Non- Cycling never initiated cyclicity. Start-Stop heifers segregated into Start-Stop- Discontinuous (SSD) or Start-Stop-Start (SSS), with SSD having similar phenotypes to Non-Cycling and SSS to Typical heifers. We hypothesized that these pubertal classifications are heritable, and loci associated with pubertal classifications could be identified by genome wide association …

Faculty, Staff and Student Publications

The RE1 silencing transcription factor (REST) is a driver of sonic hedgehog (SHH) medulloblastoma genesis. Our previous studies showed that REST enhances cell proliferation, metastasis and vascular growth and blocks neuronal differentiation to drive progression of SHH medulloblastoma tumors. Here, we demonstrate that REST promotes autophagy, a pathway that is found to be significantly enriched in human medulloblastoma tumors relative to normal cerebella. In SHH medulloblastoma tumor xenografts, REST elevation is strongly correlated with increased expression of the hypoxia-inducible factor 1-alpha (HIF1α)-a positive regulator of autophagy, and with reduced expression of the von Hippel-Lindau (VHL) tumor suppressor protein - a …

Uveal melanoma (UM) is the deadliest form of eye cancer in adults. Inactivating mutations and/or loss of expression of the gene encoding BRCA1-associated protein 1 (BAP1) in UM tumors are associated with an increased risk of metastasis. To investigate the mechanisms underlying this risk, we explored the functional consequences of BAP1 deficiency. UM cell lines expressing mutant BAP1 grew more slowly than those expressing wild-type BAP1 in culture and in vivo. The ability of BAP1 reconstitution to restore cell proliferation in BAP1-deficient cells required its deubiquitylase activity. Proteomic analysis showed that BAP1-deficient cells had decreased phosphorylation of ribosomal S6 and …

Slime Molds (Myxomycetes) Causing A “Disease” In Crop Plants And Cultivated Mushrooms, Zhaojuan Zhang, Chao Zhi, Yu Li, Steven L. Stephenson, Pu Liu

Biological Sciences Faculty Publications and Presentations

Myxomycetes (plasmodial slime molds) are eukaryotic protist predators that are associated with wood, leaf litter, and soil in forests, where they feed on bacteria, protozoans, and (to a more limited extent) fungi. The health of crop plants is essential because they represent a primary food source for humans. However, when myxomycetes produce numerous fruiting bodies on the stems and leaves of crop plants, which is herein referred to as a myxomycete colonization, this has the potential of interfering with plant photosynthesis, transpiration and respiration by blocking out light and covering stomata. Myxomycetes are not pathogens, but their occurrence on plants …

Malnutrition Alters Protein Expression Of Kndy Neuropeptides In The Arcuate Nucleus Of Mature Ewes, Jennifer F. Thorson, Ligia D. Prezotto

Department of Animal Science: Faculty Publications

The neuropeptides kisspeptin, neurokinin B, and dynorphin A are imperative for the pulsatile secretion of gonadotropin-releasing hormone and luteinizing hormone to ultimately regulate reproductive cyclicity. A population of neurons co-expressing these neuropeptides, KNDy neurons, within the arcuate nucleus of the hypothalamus (ARC) are positioned to integrate energy status from afferent neuronal and glial cells. We hypothesized that KNDyexpressing neurons in the ARC of mature ewes are influenced by energy balance. To test this hypothesis, ovary-intact, mature ewes were fed to lose, maintain, or gain body weight and hypothalamic tissue harvested during the luteal phase of the estrous cycle. Fluorescent, multiplex …
