Investigating And Characterizing Septin Cellular Regulators During Infection Related Development In M. Oryzae, Rinalda Proko
Investigating And Characterizing Septin Cellular Regulators During Infection Related Development In M. Oryzae, Rinalda Proko
Graduate Theses and Dissertations
The fungus Magnaporthe oryzae causes a devastating disease of rice and wheat, called blast, which poses a major threat to food security across the planet. To enter plant tissue, M. oryzae produces a remarkable pressure-generating infection cell called an appressorium, which mechanically ruptures the tough cuticle of host leaves through the application of enormous physical force directed onto a narrow penetration structure emerging from its base. Importantly, appressorium form and functionality depends on the regulated assembly of a toroidal ring-like structure, composed of septins, which forms within its base. Septins are a family of membrane-associated GTP-binding proteins that polymerize into …

The Future Of Public And Private Plant Breeding According To Plant Scientists, Lexie Burris
The Future Of Public And Private Plant Breeding According To Plant Scientists, Lexie Burris
Graduate Theses and Dissertations
Plant breeding has been effective in addressing food insecurity by increasing agricultural yields and productivity. Historically, public plant breeding programs have long-term, integrated approaches to plant breeding research, germplasm enhancement, and variety development, but as funding is reduced the future is less certain as to areas of focus. This survey builds off those before it and asks the next logical question, if a divergence between private and public breeding is taking place, what aspects should each sector focus on? The impetus of this study was to ask opinions of plant breeders globally regarding the direction they believe the public and …
The Economic Effects Of Covid-19 On Smallholder Farmers In Kenya, Sarah Hope Brasche
The Economic Effects Of Covid-19 On Smallholder Farmers In Kenya, Sarah Hope Brasche
Graduate Theses and Dissertations
Like many Sub-Saharan African countries, the Kenyan economy heavily relies on agriculture. Agriculture in Kenya accounted for 50% of the total workforce in 2019 and 70% of the rural workforce. Though reliant on agriculture for employment and subsistence, Kenya has been historically impoverished and malnourished. Kenya has been experiencing an economic recession since 2018, which was exacerbated by the COVID-19 pandemic. Relatively speaking to other African countries, Kenya managed to escape the worst health effects of the pandemic, but the economic effects were substantial. This study analyzes survey responses from 1,059 Kenyan smallholder agricultural producers on the economic impacts they …

Consumer Valuation Of Rice Quality In Colombia, Juliann Phillips
Consumer Valuation Of Rice Quality In Colombia, Juliann Phillips
Graduate Theses and Dissertations
Rice is a crucial contributor to global food security and is an important staple for over half the world’s population. In Colombia, total rice consumption has grown by 25% in the last decade (2011-2021), reaching 1.9 MMT in 2021, yet in 2021 around 15.5 million Colombians were classified as food insecure. Colombia is the third largest rice producer in Latin America, producing 1.8 million metric tons (milled basis) in 2021. Increasing rice consumption coupled with high levels of food insecurity highlights the necessity that rice markets effectively price rice according to consumer preferences. Therefore, the goal of this study focuses …
Injectable Immunomodulatory Strategies To Enhance Muscle Recovery Following Injury, Tai Huu Huynh
Injectable Immunomodulatory Strategies To Enhance Muscle Recovery Following Injury, Tai Huu Huynh
Graduate Theses and Dissertations
Although skeletal muscle displays an astonishing regenerative capacity, injuries or diseases that resulted in bedridden or chronic muscle wasting can overwhelm this intrinsic feature of skeletal muscle and lead to functional deficit (range of motion and/or strength) and overall reduction in quality of life. Microenvironmental cues within injured skeletal muscle dictate regenerative and repair process which are tightly coordinated interplay among resident cells, cells recruitment and immune response following an assault in the muscle extracellular matrix (ECM). The successful regeneration of functional tissues requires both appropriate modulation of the inflammatory response, and activation of a variety of cell populations. Biomaterials …

The Influence Of Climate And Landscape On Allocapnia Mohri Distribution In Arkansas, Brianna Leigh Annaratone
The Influence Of Climate And Landscape On Allocapnia Mohri Distribution In Arkansas, Brianna Leigh Annaratone
Graduate Theses and Dissertations
Stoneflies are a globally threatened aquatic insect order. In Arkansas, a diverse group of winter stonefly (Capniidae: Allocapnia) have not been surveyed since the 1980s, likely because species-level identification requires the rarely-collected adult form. Allocapnia mohri, a regional endemic, was previously commonly found in mountainous, intermittent streams from the Ouachita Mountains ecoregion north to the Ozark Highlands, but no species distributional models including land use or climate variables exist to our knowledge. We collected adults from 70 stream reaches from the historic Arkansas range from November to April 2020 and 2021. We modeled distributions using random forest (RF) models populated …
Evaluation Of Heat Stress And Dietary Amino Acid Density On Nutrient And Energy Partitioning In Broilers, Jean-Remi Teyssier
Evaluation Of Heat Stress And Dietary Amino Acid Density On Nutrient And Energy Partitioning In Broilers, Jean-Remi Teyssier
Graduate Theses and Dissertations
The simultaneous increase in the global demand for animal-based protein products and the rise in temperature associated with global warming pose important challenges to the poultry industry. Heat stress (HS) occurs when an animal’s heat production (HP) surpasses its capacity to dissipate heat into the surrounding environment, ultimately leading to reduced feed intake (FI) and negative impacts on performance. A better understanding of bird responses to elevated temperatures is required to propose effective nutritional strategies that mitigate the adverse effects of HS. Therefore, this dissertation aimed to characterize the nutritional and physiological mechanisms explaining the loss in performance and carcass …

The Effect Of Herbal Adaptogen On Feeding-Related Hypothalamic Neuropeptides In Heat-Stressed Broilers, Maryam Afkhami Ardakani
The Effect Of Herbal Adaptogen On Feeding-Related Hypothalamic Neuropeptides In Heat-Stressed Broilers, Maryam Afkhami Ardakani
Graduate Theses and Dissertations
Heat stress is a major issue in the poultry industry, having numerous negative consequences for chicken productivity. Decreasing feed intake is one of these issues, which results in higher mortality and poor growth performance. Moreover, Herbal adaptogens, plant extracts that are also known as stress response modifiers, are metabolic regulators that improve an organism's ability to adapt to environmental stresses and minimize damage from such stressors. Previously, we published data indicating that herbal adaptogen supplementation increased feed intake under heat stress conditions. Therefore, we hypothesized that dietary herbal adaptogen supplementation might exert these effects through alteration of the expression of …
Investigation Of Consumer Freezing Practices, Condition And Duration On Palatability Of Beef, Elizabeth Sue Neal
Investigation Of Consumer Freezing Practices, Condition And Duration On Palatability Of Beef, Elizabeth Sue Neal
Graduate Theses and Dissertations
The objective of these studies was to determine: the impact of extended periods of frozen storage duration and packaging type on palatability traits of cooked beef steaks from two muscles and the impact of freezing type and storage duration on objective and subjective measures of ground beef palatability traits. In study 1, no differences were elicited from any of the possible interactions (P= 0.95) for SSF or CL: package × muscle × freezing duration, package × muscle, package × duration or muscle × duration. However, freezing duration did impact both SSF (P < 0.01) and CL (P < 0.001). Generally, for both SSF and CL steaks that were frozen for 9-months elicited both the highest SSF values as well as the greatest percentage of CL among all treatments. In comparison, EM was impacted by the interaction (P = 0.059) of packaging type muscle freezing duration. Samples from OW GM stored for 9-months elicited the highest percentage of EM while fresh OW LL samples resulted in the lowest. Additionally, expressible moisture was impacted by the interaction (P = 0.047) of muscle freezing duration. Among all treatments, GM steaks that were frozen for 9-months elicited the highest EM values and fresh LL samples the lowest EM values. Contrastingly, there was no significant difference observed in expressible moisture for the interaction (P 0.18) of package type freezing duration or for the interaction (P = 0.70) of package type muscle. Generally, fresh OW GM steaks resulted in the greatest concentration of lipid derived volatile compounds such as aldehydes, hydrocarbons and alcohols which contrasted sensory ratings of trained panelists that indicated oxidized and refrigerator-stale ratings increased as storage time increased for OW steaks. In study 2, The interaction of freezer treatment × storage duration impacted gumminess (P = 0.05), a TPA attribute. In greater detail, samples stored in RF for 6-months resulted in the greatest gumminess values (P < 0.001), while those stored in the CF for 12-months elicited the lowest (P < 0.001). Similarly, flavor development was also impacted by the interaction (P = 0.05) of freezer treatment × storage duration. Three lipid derived compounds were of greatest concentration among RF patties stored for 1-month. In contrast, the interaction of freezer treatment × storage duration elicited no impact on consumer ratings, SF or TBARS. Nonetheless, frozen storage duration impacted TPA, flavor development, consumer ratings, SF and TBARS as a main effect (P < 0.05), especially in regard to tenderness and juiciness. Moreover, beef flavor development, tenderness and juiciness are impacted by freezing duration, muscle, freezer type and packaging, however these factors are not necessarily independent of one another. Furthermore, the retail display period is a critical period for fresh beef steaks, especially when packaged in aerobic conditions. For optimal eating experience, beef products should be stored for extended periods in a vacuum packaging, in a designated freezer that is not opened frequently to allow for optimal air flow regulation and minimize freezer burn to improve tenderness and juiciness.
Use Of Microorganisms For The Enrichment Of Zn And Se By Using Solid-State Fermentation, Rashmi Rangaswamaiah
Use Of Microorganisms For The Enrichment Of Zn And Se By Using Solid-State Fermentation, Rashmi Rangaswamaiah
Graduate Theses and Dissertations
Zinc (Zn) and selenium (Se) are essential minerals for human health and naturally found in many food sources. However, the risk of Zn and Se deficiency has been recognized in several countries. As most people throughout the world consume rice, grains, and cereals as staple foods in their daily diet, which contain a certain amount of phytic acid (antinutrients), the phytic acid content inhibits mineral absorption (Zn and Se) by the human body. Moreover, the low levels of Zn and Se content found in the crop's soil also reduce the amount of minerals in the food sources. Therefore, it is …

Starch Granule And Crystalline Structures With Relation To Enzyme Digestibility, Ana Isabel Gonzalez Conde
Graduate Theses and Dissertations
Porous starch produced by enzyme hydrolysis has attracted much attention for its adsorption and delivery properties. Porous starch has been successfully prepared from A-type starch, but not from B-type and C-type starches, which is partly attributed to the surface and crystalline structure. The present study aimed to characterize the role of the crystalline structure and the structure-function relationship impacting the susceptibility of starch with different crystalline polymorphs to amylase digestion. The starches were subjected to chemical modification (acid hydrolysis or surface gelatinization), physical modification (heat-moisture treatment, HMT, or high-pressure processing, HPP) or their combinations prior to amylase digestion, and the …
An Investigation Of Seed Hardness And Seed Coat Color Values In Natto Soybean, Joshua Winter
An Investigation Of Seed Hardness And Seed Coat Color Values In Natto Soybean, Joshua Winter
Graduate Theses and Dissertations
Natto is a specialty fermented soyfood made from small-seeded (seeds-1) soybean varieties. Seed hardness and seed coat color are important seed traits that determine the texture and appearance of natto and are thus valuable to breeders. Prior research has identified quantitative trait loci (QTL, hereafter) for seed hardness, but its nature as a quantitative trait heavily influenced by the environment means that it is still poorly understood. Prior research has identified the primary genetic components of seed coat color using simple visual inspection, but few studies have investigated the usefulness of more quantitative measurements, such as the color space coordinates …
