Genome-Wide Association Study Identified Candidate Genes For Alkalinity Tolerance In Rice, Lovepreet Singh, Rajat Pruthi, Sandeep Chapagain, Prasanta K. Subudhi

Faculty Publications

Alkalinity stress is a major hindrance to enhancing rice production globally due to its damaging effect on plants’ growth and development compared with salinity stress. However, understanding of the physiological and molecular mechanisms of alkalinity tolerance is limited. Therefore, a panel of indica and japonica rice genotypes was evaluated for alkalinity tolerance at the seedling stage in a genome-wide association study to identify tolerant genotypes and candidate genes. Principal component analysis revealed that traits such as alkalinity tolerance score, shoot dry weight, and shoot fresh weight had the highest contribution to variations in tolerance, while shoot Na+ concentration, shoot Na+:K+ …

Aleman, Shirin Kazemzadeh Pournaki, Mallerly Sarmiento Madrid, Andrea Muela, Yeimi Mendoza, Jhunior Marcia Fuentes, Witoon Prinyawiwatkul, Joan M. King

Faculty Publications

Gluten-free bread is an important product that is under development using different sources, such as rice and starchy plants. Teosinte seeds are utilized by ethnic groups in Honduras to produce gluten-free flour to prepare traditional baked goods and beverages. The quality of gluten-free products could vary depending on flour properties, such as amylose content, particle size, and water absorption capacity. A good strategy for developing baked goods is to mix different cereal grain sources to optimize their physicochemical properties. As a result, the current study aimed to develop bread from novel flours including teosinte (TF), high-protein brown rice (BRF), and …

Silica Concentrations In Dominant Vegetation Species Of Wax Lake Delta, Louisiana, Danielle M. Soileau

LSU Master's Theses

Coastal deltaic wetlands colonize dynamic environments and experience fluctuations of salinity, river connectivity, sediment dredging or deposition, and periods of inundation resulting in unique vegetation and soils. Louisiana’s coastline is experiencing enhanced loss of coastal deltaic wetlands in coastal basins where the Mississippi River no longer is connected to waterways and channels that would normally provide freshwater and sediments representing the abandonment phase of the delta cycle. There is a coastal basin in the central regions of the state, the Atchafalaya Bay, that is still in the active phase of delta cycle resulting in the growth of the Wax Lake, …

Measuring Food Literacy Among Limited-Resourced Adults, Emelia Clement

LSU Doctoral Dissertations

Food literacy is the interrelated knowledge, skills and behaviors needed to plan and manage, select, prepare, and eat healthy food. It is positively associated with improved consumption of nutritious diets, and can be beneficial to limited-resource adults, who are often at risk for chronic diet-related diseases. Valid instruments for measuring food literacy in this population are scarce but urgently needed. The Eating and Food Literacy Behavior Questionnaire (EFLBQ) can be used to measure food literacy among limited-resource audiences.

Part one of this study aimed to determine the fitness of the EFLBQ to measure food literacy in limited-resource adults. A convenience …

Niche Specialization And Community Niche Space Increase With Species Richness In Filter-Feeder Assemblages, Irene Sánchez González, Garrett W. Hopper, Jamie R. Bucholz, Megan E. Kubala, Jeffrey D. Lozier, Carla L. Atkinson

Faculty Publications

Ecological theory posits that higher species richness should be associated with greater exploitation of resources and niche packing resulting from either increasing species niche overlap or specialization of species' niches. Research evaluating niche theory in animals tends to focus on organisms among functional feeding guilds, while resource partitioning might be more critical within functional groups. Freshwater mussels (Family: Unionidae) are a diverse and imperiled group of animals that are ideal models to test niche occupancy due to their functional similarity as filter-feeders and their occurrence in spatially and temporally stable multispecies aggregations. We evaluated the relationship between species richness and …

Results: Nine postmenopausal women (mean [SD], age 59 [4] years, …

Learning About Our Vices From Devices: A Model Of Individual Learning With An Application To Consumer Food Waste, Danyi Qi, Brian E. Roe, John W. Apolzan, Corby K. Martin

Clinical Research Faculty Publications

We formulate an empirical learning model suitable for understanding individual behavioral responses to personal devices and sensors. We estimate this model using data collected about personal decisions of food selection, intake, and waste during a study in which users photographed their meal selections and plate waste over the course of a week with a cell phone. We found substantial learning-by-doing effects in plate-waste reduction: Those who document greater plate waste in their photographs waste less on subsequent days. Further, we identified that participants reduced plate waste by learning to eat more rather than by learning to select less food.

Assessing The Nutritional Value Of Dubia Roaches (Blaptica Dubia) As A Feeder Insect In Reptiles, Elise Barras

LSU Master's Theses

Dubia roaches (Blaptica dubia) have emerged on the market as a high protein and low-fat alternative to other feeder insects for captive reptiles. However, much like other insects, dubia roaches naturally have an inverse calcium to phosphorus (Ca:P) ratio. Offering insects to reptiles that are deficient in calcium can lead to nutritional disease (e.g., nutritional secondary hyperparathyroidism). For dubia roaches to be a valuable feeder insect, their Ca:P ratio must be corrected. Several studies have assessed their nutritional composition, but no studies have manipulated the calcium content of these insects. Using a high calcium (8.3% calcium, dry matter) …

Influence Of Metabolic Interventions On Animal Aging And Lifespan, Bhaswati Ghosh

LSU Doctoral Dissertations

Aging is associated with metabolic rewiring. Most lifespan-extending longevity interventions target metabolic pathways. Genetic or pharmacological metabolic approaches that mediate longer lifespan and healthspan, are often linked to detrimental effects on human health. Here, I show that supplementation of botanical extracts from Artemisia scoparia (SCO), dramatically increases animal lifespan. Mechanistically, this lifespan extension is dependent on AMPK-DAF-16 signaling via inhibition of the insulin pathway. In SCO-fed worms, longer lifespan was accompanied by higher fat storage and improved resiliency to age-related physiological stress. Notably, DAF-16, the master regulator of longevity, activated the fatty acid desaturation processes, which promoted the accumulation of …

Domain Specific Analysis Of Privacy Practices And Concerns In The Mobile Application Market, Fahimeh Ebrahimi Meymand

LSU Doctoral Dissertations

Mobile applications (apps) constantly demand access to sensitive user information in exchange for more personalized services. These-mostly unjustified-data collection tactics have raised major privacy concerns among mobile app users. Existing research on mobile app privacy aims to identify these concerns, expose apps with malicious data collection practices, assess the quality of apps' privacy policies, and propose automated solutions for privacy leak detection and prevention. However, existing solutions are generic, frequently missing the contextual characteristics of different application domains. To address these limitations, in this dissertation, we study privacy in the app store at a domain level. Our objective is to …

Effect Of Furosemide Administration On Plasma Analytes And Urine Enzyme Excretion In Two Reptilian Species, Kathryn Metcalf

LSU Master's Theses

Renal disease is a common ailment of captive reptiles that is often closely linked to chronic, subclinical states of dehydration. Currently, the diagnosis of renal disease in reptiles is poorly characterized and often relies on invasive diagnostic techniques (e.g., renal biopsy) for definitive diagnosis. A potential outlet for the further characterization of renal dysfunction in reptiles is the induction of dehydration by furosemide therapy. Furosemide is a loop diuretic that is commonly used in mammalian patients for the treatment of congestive heart failure. The utility of furosemide in reptiles is poorly characterized, however, both experimental and clinical utility of this …

Natural Lights & Natural Rights: The Problem Of The New Classical Natural Law Theory, Charles Neville Cacciatore

LSU Master's Theses

The present work examines the natural law jurisprudence of John Finnis. It argues that Finnis’s teaching is a genuinely new natural law theory. Finnis’s jurisprudence is not a re- presentation of the jurisprudence of St. Thomas Aquinas because its central element—a doctrine of natural rights—is a departure from Aquinas’s natural law teaching. In support of these claims, the present work relies upon the scholarship of Ernest L. Fortin, A.A. Following Fr. Fortin, it presents an understanding of the natural law that endorses a clear distinction between natural right and natural rights—between premodern political philosophy and modern political philosophy.

Snacking Consumption Among Adults In The United States: A Scoping Review, Jean Pierre Enriquez, Elizabeth Gollub

Snacks are a staple of the American diet, contributing to approximately 20% of energy intake. Most U.S. adults consume one to three snacks/day, yet few reviews have focused on snacking among this population. This scoping review was conducted to characterize snacks and snacking occasions among U.S. adults to further inform healthy eating practices. The protocol was prepared following the PRISMA-Extension for Scoping Reviews. Three web databases were used to identify articles using snacking or eating occasions as primary or secondary outcomes among U.S. adults. A search strategy was developed using subject headings, truncation, and phrase searching in the title and …

Horizontally Transferred Genes As Rna Interference Targets For Aphid And Whitefly Control, Honglin Feng, Wenbo Chen, Sonia Hussain, Sara Shakir, Vered Tzin, Femi Adegbayi, Todd Ugine, Zhangjun Fei, Georg Jander

Faculty Publications

RNA interference (RNAi)-based technologies are starting to be commercialized as a new approach for agricultural pest control. Horizontally transferred genes (HTGs), which have been transferred into insect genomes from viruses, bacteria, fungi or plants, are attractive targets for RNAi-mediated pest control. HTGs are often unique to a specific insect family or even genus, making it unlikely that RNAi constructs targeting such genes will have negative effects on ladybugs, lacewings and other beneficial predatory insect species. In this study, we sequenced the genome of a red, tobacco-adapted isolate of Myzus persicae (green peach aphid) and bioinformatically identified 30 HTGs. We then …

Melatonin Treatment Of Strawberry Fruit During Storage Extends Its Post-Harvest Quality And Reduces Infection Caused By Botrytis Cinerea, Surassawadee Promyou, Yenjit Raruang, Zhi Yuan Chen

Faculty Publications

Gray mold is a main disease of strawberry fruit (Fragaria × xananassa cv. Camino Real) caused by Botrytis cinerea, which leads to marketable value losses in the supply chain. The purpose of this study was to investigate the effects of exogenous melatonin (MT) on the physicochemical quality, antioxidant defense system, and disease resistance of strawberry fruit to B. cinerea infection. The results revealed that strawberry fruit immersed in 100 µM MT for 15 min effectively maintained its brightness and delayed the change in fruit color. MT also maintained the level of titratable acidity and slowed down the increase of total …

In the published version on page 5, subchapter 5.1 Heart and large arteries, right column, the paper by Booth et al. (2021) was erroneously quoted as describing DMX cardiac neurons conducting at about B-fiber speed. However, these authors only described DMX neurons in general and not specifically cardiac neurons. Thus, the term “cardiac” should be deleted in lines 7 and 9. Also, in line 7, conduction speed should be 6 m/s.
