A Novel Strategy Of Mycorrhizal Fungi Usage To Enhance Crop Resilience In Saline Environments: Biopriming With Serendipita Indica, Tuğba Özteki̇n, Meli̇sa Ayişiği, Lale Yildiz Aktaş

Turkish Journal of Botany

Soil salinization is a critical global challenge, threatening agricultural productivity by imposing osmotic stress, ionic toxicity, and oxidative imbalance in plants. This study investigated the potential of Serendipita indica biopriming to enhance salt stress tolerance in maize (Zea mays L. cv. Simon) seedlings through comprehensive physiological and biochemical analyses under controlled conditions. Maize seeds were bioprimed with different concentrations of mycorrhizal fungi S. indica spores and exposed to varying NaCl concentrations (0, 50, 100, and 200 mM). Nonprimed maize seedlings had a gradual reduction in seed vigor index, reaching about 93.56% in 200 mM NaCl treatment. Under nonsaline conditions, S. …

The origin of cancer is poorly understood because premalignant cells are rarely followed in their native environments. Although the spatial compartmentalization of metabolic functions is critical for proper liver function, it is unknown whether cancers arise from some zones but not others and whether there are metabolic determinants of cancer risk. Zone-specific, mosaic introduction of Ctnnb1 (catenin beta 1) and Arid2 (AT-rich interaction domain 2) mutations, commonly co-mutated genes in hepatocellular carcinoma (HCC), in mouse models showed that position and metabolic context determine clone fates. Ctnnb1/Arid2-driven cancers were much more likely to arise in zone 3. The …

Drought × Herbivory Induce Leaf Trichomes In Soybean With Differential Impact On Its Major Herbivore Soybean Looper Chrysodeixis Includens, Manish Gautam, Karen Alanis, Rupesh R. Kariyat

School of Integrative Biological & Chemical Sciences Faculty Publications

Trichomes have been well studied as a physical defense against stress. With climate change, stressors like drought and/or herbivory can have exacerbated effects on crop morpho-physiology. However, the interactive effects of such stressors on physical defenses like trichomes and their effects on herbivores is poorly understood. To examine this, soybean plants were exposed to a major herbivore, soybean looper (SBL) (Chrysodeixis includens Walker), under simulated drought conditions to examine the interactive effects of drought and herbivory (D × H) on leaf trichomes. Additionally, SBL growth traits were monitored under different leaf diet concentrations (10% and 20%) and trichome enriched diets …

Association Of Hair Shedding Level With Cow–Calf Performance In Summer-Bred Dexter Cattle, Ichard Browning Jr, Emily G. Hayes, Kaylee S. Hillin, Maria Lenira Leite-Browning

Food and Animal Sciences Faculty Research

Reduced winter hair shedding in beef cows through the spring and summer months may contribute to heat stress and reduced performance in spring-calving herds. This study evaluated the relationship of hair shedding with the fertility and maternal performance of 72 Dexter cows. Hair shedding data for 20 May, 3 June, 17 June, and 1 July in 2019 were used to classify cows as high or low hair shedders. Hair shedding levels were lower (p < 0.05) for 2-year-old cows than for cows 7+ years of age for the first three dates and lower (p ≤ 0.05) for lactating cows than for dry cows on the first two dates. Concurrent and four years of historical performance records were used to assess the associations between hair shedding and cow–calf performance. Data from 230 natural matings in July and August from 2015 to 2019 were analyzed. Birth to weaning weight data were recorded from 2016 to 2019 on 124 spring-born calves. Cow fertility was higher (p < 0.05) for high-shed cows than for low-shed cows for the 1 July classification. When the records from cows that were dry in 2019 were excluded from testing, fertility was higher (p < 0.05) for high-shed cows than for low-shed cows at all four scoring dates. The associations of cow hair shedding levels with preweaning calf performance were minimal. Dexter cows exhibiting higher hair shedding levels in the spring and summer expressed higher summer fertility.

Coexisting Salps Exhibit Distinct Feeding Selectivity On Microorganisms In The North Pacific Subtropical Gyre, Anne W. Thompson, Kylee Lamberson, Kelly R. Sutherland

Biology Faculty Publications and Presentations

Mortality mechanisms play an important role in how oceanic microorganisms contribute to global biogeochemical cycles. Salps are widespread pelagic tunicates known to remove phytoplankton from coastal and high-latitude waters, but their interaction with microorganisms in the vast tropical and subtropical gyres is not well quantified. Using quantitative measurements of six major marine microorganisms in the guts of six distinct but co-occurring salp species from the North Pacific Subtropical Gyre, we examined the impact and dynamics of salp feeding on marine microorganisms in a vast open ocean region. All salps preferentially removed prey greater than 1 μm in diameter, including marine …

Department of Nutrition Student Projects

Abstract

Background:

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and dual glucose-dependent insulinotropic polypeptide/glucagon-like peptide-1 receptor agonists (GIP/GLP-1 RAs) have revolutionized obesity management, producing unprecedented weight loss outcomes. Their widespread use has outpaced research on nutritional implications, adverse events, and evidence-based guidance for dietitians. Given the central role of nutrition practitioners in supporting adults with obesity, understanding the mechanisms, risks, and nutrition-related outcomes of GLP-1 therapies is critical.

Methods:

A comprehensive literature search was conducted utilizing PubMed, Embase, and Google Scholar to identify relevant peer-reviewed articles on the topic of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) use and nutrition-related …

Differentiation In The Human Urothelia Is Defined By Distinct Alternative Polyadenylation, Ninh B Le, Surbhi Sona, Briana Santo, Yi Zhang, Rosie Ou, R Allen Schweickart, Veena Kochat, William I Padron, Kunal Rai, Shih-Han Lee, Joo Mi Yi, Oliver Wessely, Byron H Lee, Angela H Ting

Faculty, Staff and Student Publications

Distinct epithelial cell states arise during differentiation, but mechanisms generating transcriptomic diversity among them remain poorly defined. The human ureter urothelium contains basal progenitor, intermediate cells, and terminally differentiated umbrella cells. Prior single-cell RNA sequencing revealed similar global gene expression profiles across these states, raising the question of how distinct identities emerge. Here, we show that alternative cleavage and polyadenylation (APA) introduces a major layer of transcriptomic diversity during urothelial differentiation, largely independent of changes in mRNA levels. Analysis of 13,544 urothelial cells identified hundreds of differentiation-associated APA events. Single-cell imaging revealed spatially specific APA patterns, and reporter assays demonstrated …

An Antioxidant Cocktail Of Tert-Butylhydroquinone And A Manganese Porphyrin Induces Toxic Levels Of Oxidative Stress In Cancer Cells, Sandra Tamarin, Hannah Jung, Joseph Lamorte, Laura Biesterveld, Gabriel Piñero, Grace Turchetta, Molly Myers, Rebecca Oberley-Deegan, Aimee Eggler

Student Papers, Posters & Projects

Despite significant advancement in cancer treatments, therapies with minimal toxicity to healthy cells are still limited. One targetable weakness of cancer cells is their sensitivity to oxidative stress. We find that the combination of two antioxidants—the common food additive tert-butylhydroquinone (tBHQ) and a manganese porphyrin in clinical trials, MnTnBuOE-2-PyP5+ (MnBuOE)—increases oxidative stress and causes apoptotic death in several cancer cell lines, but not in mouse primary fibroblasts. Investigating the mechanism of cell death, MnBuOE is observed to catalyze the oxidation of tBHQ, producing the electrophilic quinone tert-butylquinone (tBQ). A critical role for tBQ and its electrophilic character was revealed with …

All Peer-Reviewed Publications

Human activities, either intentional or unintentional, have significantly influenced the global distribution and genetic composition of many species. The black soldier fly (Hermetia illucens; BSF) is a species native to North America that has rapidly gained commercial importance due to its bioconversion efficiency, upcycling organic waste into higher-value products. Through human-mediated dispersal associated with trade and insect farming, BSF has been introduced widely across the Old World, including Africa, where both wild and captive populations are now established. Despite its expanding global distribution, the demographic history and genomic consequences of these introductions remain poorly understood, particularly in Africa. This work …
