Determining Effects Of Management Practices On Potato Early Dying And Soil Microbiome And Assessing Risk Of Fungicide Resistance In Verticillium Dahliae, Kedi Li
Electronic Theses and Dissertations
Potato early dying (PED) is a yield-constraining soilborne disease of potato, caused by Verticillium spp. with V. dahliae being the predominant causal agent. Since the pathogen inhabits soil for long periods, PED management aims to reduce the population of V. dahliae in soil. Benzovindiflupyr and azoxystrobin are effective chemicals and frequently used in the control of V. dahliae. In this study, field trials were conducted at Aroostook Farm, Presque Isle, ME in 2019 and 2020. Chemical and biological products have been studied for PED control, and fungicide resistance was also examined. To evaluate fungicide resistance, benzovindiflupyr was characterized on sensitivity ...
Trained Immunity Enhances The Immune Response And Maintains Microbiome Diversity In Aging And Sepsis, 2021 East Tennessee State University
Trained Immunity Enhances The Immune Response And Maintains Microbiome Diversity In Aging And Sepsis, P. Spencer Gill
Electronic Theses and Dissertations
The global population is rapidly aging. It is estimated that over the next thirty years, the number of individuals >60 years of age will increase by over a billion, and the number of individuals over age 80 may increase by 300 million. As humans age, our immune system becomes progressively weaker through a process called immune senescence. This age-related decrease in immune function increases susceptibility to infection and chronic diseases. Sepsis is a leading cause of death worldwide. Over the past two decades, there has been an increased incidence of sepsis which is due, in part, to our aging population ...

Advances in Clinical Medical Research and Healthcare Delivery
Lyme disease is caused by a bacteria belonging to the Borreliaceae family. Wooded forests and terrains are affected, including those in the Northeastern United States. Teenage ticks are most commonly discovered on humans as those ticks need to satisfy their nutritional requirements for growth. They bite warm, moist areas of the body and take 24 to 48 hours to transmit the Borrelia Burgdorferi infection. Lyme disease manifests as a multisystem disorder in humans, and is known for its dermatological, neurological and rheumatological findings. For the primary care provider, Lyme disease should be on the differential in multisystem diseases. Our case ...

Journal of Bioresource Management
Entomopathogenic fungi (EPF) specifically infect and kill insects can serve as a potential biological control agent. Several biotic and abiotic factors affect their occurrence, persistence, and epizootics caused by them. In biotic factors, fungi characters (host range, latency, spore density and dispersal, mainly host-pathogen compatibility), insect host factors (behavioral, morphological, and physiological), plant-mediated effects (plant architecture, surface chemistry, and leaf topology) are included supports or causes the barrier to mycobiopesticide. Abiotic factors which affect the EPF field persistence are mainly environmental (temperature, sunlight, humidity, rainfall) physical and chemical soil properties (soil texture, pH, E.c, moisture, C/N content, and ...

Plastic Biodegradation Through Insects And Their Symbionts Microbes: A Review, Huda Bilal, Hasnain Raza, Haseena Bibi, Tehmina Bibi
Journal of Bioresource Management
Plastic waste has recently been identified as one of the most serious environmental issues, affecting all life forms, natural habitats, and the economy, and is one of the most serious global environmental problems, second only to climate change. Seeking alternative environmentally sustainable options, such as biodegradation instead of conventional disposal, is critical in the face of this challenge. However, there is currently a lack of information about the mechanisms and efficacy of plastic biodegradation. From this perspective, this study aims to illustrate the negative environmental impacts of the plastic waste. It also addresses the role of insects and gut microbiota ...

A Nosy Neighbor: Purification And Functional Characterization Of Lpg2149, Ashley M. Holahan
The Journal of Purdue Undergraduate Research
Ubiquitination is a process that marks proteins for various cell-signaling pathways, namely protein degradation and other processes. Th ese pathways are essential in a wide array of cellular processes, including defense mechanisms against invading pathogens. Th e ubiquitination process is universally found in all eukaryotic organisms, including plants and animals, and thus plays a vital role in cellular homeostasis. Recently, more discoveries have been made on prokaryotic effector proteins that hijack the ubiquitination system even when they do not possess a ubiquitin system of their own. MavC, also known as lpg2147 (Gan, Nakayasu, Hollenbeck, & Luo, 2019; Puvar et al., 2020; Valleau et ...
Metabolic Modeling Of Cystic Fibrosis Airway Microbiota From Patient Samples, 2021 University of Massachusetts Amherst
Metabolic Modeling Of Cystic Fibrosis Airway Microbiota From Patient Samples, Arsh Vyas
Cystic Fibrosis (CF) is a genetic disorder, found with higher prevalence in the Caucasian population, affecting > 30,000 individuals in the United States and > 70,000 worldwide. Due to the astoundingly high rate of mortality among CF patients being attributed to respiratory failure brought on by chronic bacterial infections and subsequent airway inflammation, there has been a lot of focus on systematically analyzing CF lung airway communities. While it is observed traditionally that Pseudomonas aeruginosa is the most threatening and persistent CF colonizer due to high antibiotic resistance, recent studies have elicited the roles of other pathogens and it has ...
The Role Of Low-Molecular Weight Fungal Metabolites In Eutypa Dieback Grapevine Trunk Disease, 2021 University of Massachusetts Amherst
The Role Of Low-Molecular Weight Fungal Metabolites In Eutypa Dieback Grapevine Trunk Disease, Dana Sebestyen
Eutypa dieback, one of several grapevine trunk diseases (GTDs), is of serious concern to the grape industry globally. This disease is caused by the fungus Eutypa lata but it is often seen in consortia growth with Phaeoacremonium minimum and Phaeomoniella chlamydospora. It is vital to understand the mechanisms for how this disease functions to develop control measures to combat it. Brown rot fungi are able to use a complex of low molecular weight (LMW) metabolites to induce a Fenton reaction to deconstruct woody tissue. These metabolites are part of a chelator mediated Fenton (CMF) chemistry that produces reactive oxygen species ...
Structure-Function Studies Of The Trypanosome Mitochondrial Replication Protein Polib, 2021 University of Massachusetts Amherst
Structure-Function Studies Of The Trypanosome Mitochondrial Replication Protein Polib, Raveen Armstrong
Trypanosoma brucei and related protists are distinguished from all other eukaryotes by an unusual mitochondrial genome known as kinetoplast DNA (kDNA) that is a catenated network composed of minicircles and maxicircles. Replication of this single nucleoid involves a release, replicate, and reattach mechanism for the thousands of catenated minicircles and requires at least three DNA polymerase (POLIB, POLIC and POLID) with similarity to E. coli DNA polymerase I. Like other proofreading replicative DNA polymerases, POLIB has both an annotated polymerase domain and an exonuclease domain. Predictive modelling of POLIB indicates that it has the canonical right hand polymerase structure with ...
Immunometabolic Dysregulation At The Intersection Of Obesity And Covid-19, 2021 Tennessee State University
Immunometabolic Dysregulation At The Intersection Of Obesity And Covid-19, Collins N. Khwatenge, Marquette Pate, Laura C. Miller, Yongming Sang

Obesity prevails worldwide to an increasing effect. For example, up to 42% of American adults are considered obese. Obese individuals are prone to a variety of complications of metabolic disorders including diabetes mellitus, hypertension, cardiovascular disease, and chronic kidney disease. Recent meta-analyses of clinical studies in patient cohorts in the ongoing coronavirus-disease 2019 (COVID-19) pandemic indicate that the presence of obesity and relevant disorders is linked to a more severe prognosis of COVID-19. Given the significance of obesity in COVID-19 progression, we provide a review of host metabolic and immune responses in the immunometabolic dysregulation exaggerated by obesity and the ...

Coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), resulted in an unprecedented global crisis. Although primarily a respiratory illness, dysregulated immune responses may lead to multi-organ dysfunction. Prior data showed that the resident microbial communities of gastrointestinal and respiratory tracts act as modulators of local and systemic inflammatory activity (the gut-lung axis). Evolving evidence now signals an alteration in the gut microbiome, brought upon either by cytokines from the infected respiratory tract or from direct infection of the gut, or both. Dysbiosis leads to a "leaky gut". The intestinal permeability then allows access to ...

Oxidation Alters The Architecture Of The Phenylalanyl-Trna Synthetase Editing Domain To Confer Hyperaccuracy, Pooja Srinivas, Rebecca E. Steiner, Ian J. Pavelich, Ricardo Guerrera-Ferreira, Puneet Juneja, Michael Ibba, Christine M. Dunham
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
High fidelity during protein synthesis is accomplished by aminoacyl-tRNA synthetases (aaRSs). These enzymes ligate an amino acid to a cognate tRNA and have proofreading and editing capabilities that ensure high fidelity. Phenylalanyl-tRNA synthetase (PheRS) preferentially ligates a phenylalanine to a tRNAPhe over the chemically similar tyrosine, which differs from phenylalanine by a single hydroxyl group. In bacteria that undergo exposure to oxidative stress such as Salmonella enterica serovar Typhimurium, tyrosine isomer levels increase due to phenylalanine oxidation. Several residues are oxidized in PheRS and contribute to hyperactive editing, including against mischarged Tyr-tRNAPhe, despite these oxidized residues not being ...
Response Of The Soil Bacterial Community, Resistome, And Mobilome To A Decade Of Macrolide Antibiotic Contamination, 2021 The University of Western Ontario
Response Of The Soil Bacterial Community, Resistome, And Mobilome To A Decade Of Macrolide Antibiotic Contamination, Liam Paul Brown
Electronic Thesis and Dissertation Repository
Biosolids (treated sewage sludge) are used as agricultural fertilizer but are frequently contaminated with macrolide antibiotics, to which resistance is rising among historically susceptible bacteria. To determine if the land-application of macrolides carried in biosolids could promote antibiotic resistance in soil bacteria, soil plots were exposed annually to environmentally realistic or high doses of macrolides for ten years. I sequenced the bacterial 16S ribosomal DNA, metagenomic DNA, and integron gene cassettes within the treated and antibiotic-free soil to compare the compositions and diversities of the bacterial communities, antibiotic resistance genes, and mobile genetic elements. I determined that the high dose ...
Reactive Chlorine Species Reversibly Inhibit Dnab Protein Splicing In Mycobacteria, 2021 Murray State University
Reactive Chlorine Species Reversibly Inhibit Dnab Protein Splicing In Mycobacteria, Christopher Lennon Dr, Daniel Wahl, J. R. Goetz, Joel Weinberger Ii
Faculty & Staff Research and Creative Activity
Intervening proteins, or inteins, are mobile genetic elements that are translated within host polypeptides and removed at the protein level by splicing. In protein splicing, a self-mediated reaction removes the intein, leaving a peptide bond in place. While protein splicing can proceed in the absence of external cofactors, several examples of conditional protein splicing (CPS) have emerged. In CPS, the rate and accuracy of splicing are highly dependent on environmental conditions. Because the activity of the intein-containing host protein is compromised prior to splicing and inteins are highly abundant in the microbial world, CPS represents an emerging form of posttranslational ...
