Effect Of Genotypes On Rancidity Development During Storage Of Naked Oats, Aastha Gautam Jan 2023

Effect Of Genotypes On Rancidity Development During Storage Of Naked Oats, Aastha Gautam

Electronic Theses and Dissertations

Oats, rich in lipids, lipase, and unsaturated fatty acids, can develop bitterness from triglyceride hydrolysis and unpleasant aromas through unsaturated fatty acid oxidation. To counteract these effects, the processing of hulled oats includes kilning, a step aimed at inactivating the enzymes responsible for lipid degradation. Kilning plays a crucial role in preserving the quality of oats by preventing undesirable flavors development linked to lipid breakdown. Despite the benefits of free threshing and absence of a dehulling requirement in naked oats, assessing lack of enzyme inactivation during processing is crucial for potential storage rancidity issues. Our aim was to determine the …

Phosphate2 And Pin-Likes7 Affect Symbiotic Nodule Phenotypes In Soybean, Bhawandeep Kaur Jan 2023

Phosphate2 And Pin-Likes7 Affect Symbiotic Nodule Phenotypes In Soybean, Bhawandeep Kaur

Electronic Theses and Dissertations

Legumes and soil rhizobia share a symbiotic relationship, wherein rhizobia fix atmospheric dinitrogen in exchange for photosynthates from the host plant. This exchange of mutual benefits occurs in a specialized root structure called ‘nodule’. Soybean (Glycine max) nodules arise from root outer cortical cells. De novo cell differentiation of cortical cells during nodule development leads to the formation of two distinct nodule zones in the mature nodule: the central infection zone where nitrogen fixation occurs and the peripheral parenchyma zone that houses vascular bundles. Plant signaling mechanisms that dictate the development of these nodule zones are not known. To address …

Fungicide Sensitivity In P. Tritici-Repentis Diverse Population And Phenotyping Of Spelt Wheat For Multiple Diseases, Zunera Shabbir Jan 2023

Fungicide Sensitivity In P. Tritici-Repentis Diverse Population And Phenotyping Of Spelt Wheat For Multiple Diseases, Zunera Shabbir

Electronic Theses and Dissertations

Pyraclostrobin, a QoI fungicide, is extensively used in the management of fungal leaf spot diseases. In this study, 215 P. tritici-repentis isolates collected from wheat fields in South Dakota were evaluated for their sensitivity to Pyraclostrobin. Of 215 isolates, 48 isolates (22%) exhibited insensitivity based on G143A mutation and EC50 values using spore germination assay. Our results indicate reduced sensitivity to insensitivity to pyraclostrobin in some isolates suggesting regular monitoring of the P. tritici-repentis population to QoI fungicides is essential to track the evolution of insensitive population. Spelt wheat (Triticum spelta L.) is an ancient cereal that is gaining small …

Temporal, Phenotypic, And Quantitative Characterization Of Thyroid Infiltrating Mononuclear Cells During Development Of Spontaneous Autoimmune Thyroiditis In Obese Strain Chickens, Katelyn M. Clark, Chrysta N. Beck, Gisela F. Erf

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The Obese strain (OS) of chickens spontaneously develops autoimmune thyroiditis (SAT) and is a well-established biomedical model for Hashimoto’s thyroiditis in humans. Both conditions are characterized by the infiltration of thyroid glands with mononuclear immune cells resulting in the destruction of thyroid tissue and impairment of the thyroid’s endocrinological functions. Past studies described immune cell infiltration in thyroids of the OS chickens, but the time-course, cell composition, and relative amounts of the various immune cells infiltrating the thyroids have not been well defined. In this project, frozen and stored thyroid glands that were previously collected at 1, 4, 7, 14, …

The Influence Of Cover Crops On Grassland Restoration, Josh C. Poland Jan 2023

The Influence Of Cover Crops On Grassland Restoration, Josh C. Poland

Masters Theses

Grassland ecosystems comprise almost a fourth of all Earth’s land mass; however, due to ever-increasing rates of agricultural land conversion, these habitats are facing a large-scale biodiversity crisis. The degradation of grasslands extends beyond physical impacts, such as soil erosion, to include the loss of soil microbial communities as a serious risk to the health and productivity of these habitats. Cover cropping, commonly used in agriculture to revive agricultural soils, has rarely been applied to grassland restorations, and could combat or reverse the harmful effects of modern agriculture techniques. For the first chapter of my thesis, I used a greenhouse …

Addressing Soil Carbon Sequestration Response From Multispecies Dairy Forage Systems And Modeling Rangeland Beef Cow Dry Matter Intake Using Precision Enteric Emissions Measurements, Lillian J. Mcfadden

Electronic Theses and Dissertations

Regenerative agriculture is a pressing matter for the dairy industry to address cropland sustainability and carbon sequestration. One regenerative management practice that has been identified to help with row crop sustainability for key metrics like soil organic carbon (SOC) is complex covers. When producers use complex covers one of the main challenges is that it takes time to detect a change in SOC. However, simulation models are a tool that can be used to help determine if a regenerative practice is a strategy that gives the best results (i.e., increased SOC) while aligning with long-term production goals. Therefore, our objectives …

Unveiling Race Diversity And Fungicide Sensitivity Profiles Of Pyrenophora Tritici Repentis Populations In South Dakota Collected From 2021-2023, Jaswinder Kaur

Electronic Theses and Dissertations

Tan spot, a foliar disease of wheat caused by the ascomycetes fungus Pyrenophora tritici repentis (Ptr), poses a significant threat to wheat crops globally. The disease gained economic importance in the late 1970s due to shifts in farming practices, such as minimal tillage and planting on crop residues, providing favorable conditions for the pathogen to overwinter and cause infections. Ptr is classified into eight races based on the production of necrotrophic effectors—Ptr ToxA (necrosis-inducing), Ptr ToxB, and Ptr ToxC (chlorosis-inducing on respective susceptible and sensitive cultivars)—resulting in distinct symptoms on susceptible wheat differentials. The inverse gene-for-gene hypothesis of Ptr suggests …

Plant Sentience? Between Romanticism And Denial: Science, Miguel Segundo-Ortin, Paco Calvo Jan 2023

Plant Sentience? Between Romanticism And Denial: Science, Miguel Segundo-Ortin, Paco Calvo

Animal Sentience

A growing number of non-human animal species are being seriously considered as candidates for sentience, but plants are either forgotten or explicitly excluded from these debates. In our view, this is based on the belief that plant behavior is hardwired and inflexible and on an underestimation of the role of plant electrophysiology. We weigh such assumptions against the evidence to suggest that it is time to take seriously the hypothesis that plants, too, might be sentient. We hope this target article will serve as an invitation to investigate sentience in plants with the same rigor as in non-human animals.

Animal Sentience

The term sentience tends to be associated with affective valence along with affectively neutral sensory states. In the absence of evidence for affectively laden states in plants, the use of the term sentience in the exploration of plant sensory and behavioral complexity is misleading and ethically problematic for its potential to trivialize animal sentience.
