A Membrane Protein Of The Rice Pathogen Burkholderia Glumae Required For Oxalic Acid Secretion And Quorum Sensing, Asif Iqbal, George Nwokocha, Vijay Tiwari, Inderjit K. Barphagha, Anne Grove, Jong Hyun Ham, William T. Doerrler Nov 2023

A Membrane Protein Of The Rice Pathogen Burkholderia Glumae Required For Oxalic Acid Secretion And Quorum Sensing, Asif Iqbal, George Nwokocha, Vijay Tiwari, Inderjit K. Barphagha, Anne Grove, Jong Hyun Ham, William T. Doerrler

Faculty Publications

Bacterial panicle blight is caused by Burkholderia glumae and results in damage to rice crops worldwide. Virulence of B. glumae requires quorum sensing (QS)-dependent synthesis and export of toxoflavin, responsible for much of the damage to rice. The DedA family is a conserved membrane protein family found in all bacterial species. B. glumae possesses a member of the DedA family, named DbcA, which we previously showed is required for toxoflavin secretion and virulence in a rice model of infection. B. glumae secretes oxalic acid as a “common good” in a QS-dependent manner to combat toxic alkalinization of the growth medium …

Effects Of Ingested Essential Oils And Propolis Extracts On Honey Bee (Hymenoptera: Apidae) Health And Gut Microbiota, Allyson Martin Ewert, Michael Simone-Finstrom, Quentin Read, Claudia Husseneder, Vincent Ricigliano Nov 2023

Effects Of Ingested Essential Oils And Propolis Extracts On Honey Bee (Hymenoptera: Apidae) Health And Gut Microbiota, Allyson Martin Ewert, Michael Simone-Finstrom, Quentin Read, Claudia Husseneder, Vincent Ricigliano

Faculty Publications

Managed honey bee (Hymenoptera: Apidae: Apis mellifera Linnaeus) hives require frequent human inputs to maintain colony health and productivity. A variety of plant natural products (PNPs) are delivered via feeding to control diseases and reduce the use of synthetic chemical treatments. However, despite their prevalent use in beekeeping, there is limited information regarding the impact of ingested PNPs on bee health. Here, we tested the effects of different essential oils and propolis extracts on honey bee life span, nutrient assimilation, xenobiotic detoxification, and gut microbiota abundance. Brazilian propolis extract lengthened worker life span, while the other PNPs (Louisiana propolis extract, …

Weight And Protozoa Number But Not Bacteria Diversity Are Associated With Successful Pair Formation Of Dealates In The Formosan Subterranean Termite, Coptotermes Formosanus, Junyan Chen, Garima Setia, Li Hsiang Lin, Qian Sun, Claudia Husseneder Nov 2023

Weight And Protozoa Number But Not Bacteria Diversity Are Associated With Successful Pair Formation Of Dealates In The Formosan Subterranean Termite, Coptotermes Formosanus, Junyan Chen, Garima Setia, Li Hsiang Lin, Qian Sun, Claudia Husseneder

Faculty Publications

New colonies of Formosan subterranean termites are founded by monogamous pairs. During swarming season, alates (winged reproductives) leave their parental colony. After swarming, they drop to the ground, shed their wings, and male and female dealates find suitable nesting sites where they mate and become kings and queens of new colonies. The first generation of offspring is entirely dependent on the nutritional resources of the founder pair consisting of the fat and protein reserves of the dealates and their microbiota, which include the cellulose-digesting protozoa and diverse bacteria. Since termite kings and queens can live for decades, mate for life …

Minimal Shift Of Eastern Wild Turkey Nesting Phenology Associated With Projected Climate Change, Wesley W. Boone, Christopher E. Moorman, Adam J. Terando, David J. Moscicki, Bret A. Collier, Michael J. Chamberlain, Krishna Pacifici Nov 2023

Minimal Shift Of Eastern Wild Turkey Nesting Phenology Associated With Projected Climate Change, Wesley W. Boone, Christopher E. Moorman, Adam J. Terando, David J. Moscicki, Bret A. Collier, Michael J. Chamberlain, Krishna Pacifici

Faculty Publications

Climate change may induce mismatches between wildlife reproductive phenology and temporal occurrence of resources necessary for reproductive success. Verifying and elucidating the causal mechanisms behind potential mismatches requires large-scale, longer-duration data. We used eastern wild turkey (Meleagris gallopavo silvestris) nesting data collected across the southeastern U.S. over eight years to investigate potential climatic drivers of variation in nest initiation dates. We investigated climactic relationships with two datasets, one inclusive of successful and unsuccessful nests (full dataset) and another of just successful nests (successfully hatched dataset), to determine whether successfully hatched nests responded differently to weather changes than all nests did. …

Community-Wide Correlations Between Species Richness, Abundance And Population Genomic Diversity In A Freshwater Biodiversity Hotspot, Jamie R. Bucholz, Garrett W. Hopper, Irene Sánchez González, Taylor E. Kelley, Colin R. Jackson, Ryan C. Garrick, Carla L. Atkinson, Jeffrey D. Lozier

Faculty Publications

Understanding patterns of diversity across macro (e.g. species-level) and micro (e.g. molecular-level) scales can shed light on community function and stability by elucidating the abiotic and biotic drivers of diversity within ecological communities. We examined the relationships among taxonomic and genetic metrics of diversity in freshwater mussels (Bivalvia: Unionidae), an ecologically important and species-rich group in the southeastern United States. Using quantitative community surveys and reduced-representation genome sequencing across 22 sites in seven rivers and two river basins, we surveyed 68 mussel species and sequenced 23 of these species to characterize intrapopulation genetic variation. We tested for the presence of …

Labeling Effects Of Initial Juvenile Justice System Processing Decision On Youth Interpersonal Ties*, Zachary R. Rowan, Adam Fine, Laurence Steinberg, Paul J. Frick, Elizabeth Cauffman Nov 2023

Labeling Effects Of Initial Juvenile Justice System Processing Decision On Youth Interpersonal Ties*, Zachary R. Rowan, Adam Fine, Laurence Steinberg, Paul J. Frick, Elizabeth Cauffman

Faculty Publications

The juvenile justice system can process youth in myriad ways. Youth who are formally processed, relative to being informally processed, may experience more public and harsh sanctions that label youth more negatively as “deviant.” Drawing on labeling theory, the current study evaluates the relative effect of formal justice system processing on the interpersonal dynamics of youth peer networks. Using data from the Crossroads Study, a multisite longitudinal sample of first-time adolescent offenders, the current study applies augmented inverse probability weighting and generalized mixed-effects models to estimate the effects of formal processing on friendship selection processes of homophily and withdrawal and …

Webb, Sean Fogenburg, William S. Beatty, Dylan Kesler, Robert H. Blenk, Kevin M. Ringelman, Matt L. Miller, Céline Arzel, John M. Eadie

Faculty Publications

The dynamics of wintering waterfowl populations at the landscape scale are the result of complex interactions of environmental, behavioral and energetic drivers. Agent-based models provide a method to directly link these factors in a spatially explicit framework and allow the emergence of patterns from the aggregation of individual agent actions. We adapted the Spatially-explicit Waterbird Agent-based Model Program (SWAMP), originally developed for waterfowl in central California, to simulate a basin-scale population of mallards (A. platyrhynchos) wintering in the Mississippi Alluvial Valley over a four-month period (November–February). Simulated agents move within the landscape, foraging on areas made available based on a …

Characterizing The Role Of Hydraulic Retention Time On Nitrate Removal Indices In Denitrifying Bioreactors By Nonlinear Models, Yuchuan Fan, Jie Zhuang, Michael Essington, Xi Zhang, Guanghui Hua, Jehangir Bhadha, Shaopan Xia, Xuanyu Lu, Jaehoon Lee

Faculty Publications

Denitrifying bioreactors (DNBRs) are a sustainable and cost-effective practice commonly used at the edge of fields to reduce nitrate from agricultural runoff. The hydraulic retention time (HRT) is a crucial variable that affects nitrate removal rate (NRR, g N m−3 d−1), nitrate removal efficiency (NRE, %), and nitrate concentration reduction per length (Nrd, mg N L−1 m−1). In this study, two nonlinear models, the developed Michaelis-Menten (MM) model and the Mitscherlich (MT) model, were developed to characterize the relationship between nitrate removal indices (NRR, NRE, and Nrd) and HRT. This study first utilizes nonlinear models to quantitatively understand the relationship …

Responses Of Winter Wheat Yield And Water Productivity To Sowing Time And Plastic Mulching In The Loess Plateau, Lihong Wu, Hao Quan, Lina Wu, Xi Zhang, Hao Feng, Dianyuan Ding, Kadambot H.M. Siddique Nov 2023

Responses Of Winter Wheat Yield And Water Productivity To Sowing Time And Plastic Mulching In The Loess Plateau, Lihong Wu, Hao Quan, Lina Wu, Xi Zhang, Hao Feng, Dianyuan Ding, Kadambot H.M. Siddique

Faculty Publications

On the Loess Plateau, unfavorable late-sowing conditions often arise due to late harvests from the previous season or excessive rainfall during the sowing season, which can delay seed germination, reduce tiller numbers, and decrease winter wheat yields. Few studies have explored whether plastic mulching (PM) can mitigate the adverse effects of late sowing. Consequently, we conducted a 3-year field experiment from 2017 to 2020 on the Loess Plateau combining two mulching conditions [PM and no mulching (NPM)] and three sowing times (normal, 10-day late, and 20-day late sowing). We investigated the combined influence of sowing time and mulching conditions on …

Quantitative Trait Loci, Candidate Genes, And Breeding Lines To Improve Salt Tolerance At The Flowering And Seedling Stages In Rice, Rajat Pruthi, Sandeep Chapagain, Sapphire Coronejo, Lovepreet Singh, Prasant Kumar Subudhi

Faculty Publications

Salinity is a major environmental constraint that limits growth and productivity of rice all over the world. Although rice plants are vulnerable to salt stress at both seedling and flowering stages, genetic dissection of salt tolerance at the flowering stage is challenging due to non-uniformity of stress application at the appropriate growth stage. The present study was conducted to identify quantitative trait loci (QTLs) and candidate genes associated with the flowering stage salt tolerance and compare with those associated with the seedling stage using a high-resolution genetic map. A population of advanced generation introgression lines with uniform flowering time was …

Investigating Conspecific Csrv1 Transmission In Callinectes Sapidus, Julie A. Lively, Matthew I. Spitznagel, Eric J. Schott, Hamish J. Small

Faculty Publications

A reo-like virus, CsRV1, is found in blue crabs, Callinectes sapidus, from every North American location assessed, including Chesapeake Bay and the Atlantic and Gulf coasts, USA and associated with blue crabs in softshell production. CsRV1-associated crab mortality is prevalent in captive crabs, but it is still unknown how CsRV1 is transmitted. The purpose of this study was to examine the role that conspecific predation or scavenging may play in per os transmission in single exposure and repeated exposure experiments. For viruses without cell culture propagation, repeated exposure experiments have the challenge of presenting the virus consistently during the experiment …

Faculty Publications

Esports has been boosted by the proliferation of gamified social live streaming (SLS) platforms over the past few years. While previous research has recognized the complexity of gamification, limited scholarship has examined gamification effectiveness in terms of consumer loyalty in esports. Through the lens of technology acceptance model (TAM), the current study surveyed esports consumers of two SLS platforms (n = 583) to explore the relationships between gamification dimensions, TAM determinants, and SLS platform loyalty. We examined the structural model on both aggregate and segment-specific levels and revealed the existence of unobserved heterogeneity in the model's paths and observations. The …

We observed the low-mass X-ray binary Sco X-1 for 12 nights simultaneously using the Rossi X-Ray Timing Explorer and the Otto Struve Telescope at McDonald Observatory at 1-s time-resolution. This is among the most comprehensive simultaneous X-Ray/optical data sets of Sco X-1. Evidence of reprocessing was observed in the form of nine positive, near-zero lag peaks in the cross-correlation function, eight of which were relatively small, and took the shape of piecewise exponential functions. These peaks were initially identified by eye, after which a computational identification scheme was developed to confirm their significance. Based on their short lags (less than …

Faculty Publications

There is a pressing need for more-holistic approaches to fisheries assessments along with growing demand to reduce the health impacts of sample collections. Metabolomic tools enable the use of sample matrices that can be collected with minimal impact on the organism (e.g., blood, urine, and mucus) and provide high-throughput, untargeted biochemical information without the requirement of a sequenced genome. These qualities make metabolomics ideal for monitoring a wide range of fish species, particularly those under protected status. In the current study, we surveyed the relative abundances of 120 endogenous metabolites in epidermal mucus across eight freshwater fish species belonging to …

Responses Of Phytoplankton Communities To The Effect Of Both River Plume And Coastal Upwelling, Zhuyin Tong, Lingqi Ma, Shujie Cai, Lei Wang, Wupeng Xiao, Bangqin Huang, Edward A. Laws Nov 2023

Responses Of Phytoplankton Communities To The Effect Of Both River Plume And Coastal Upwelling, Zhuyin Tong, Lingqi Ma, Shujie Cai, Lei Wang, Wupeng Xiao, Bangqin Huang, Edward A. Laws

Faculty Publications

River plumes and coastal upwelling systems are both nutrient-abundant habitats compared to the open ocean, and the mechanisms that structure the phytoplankton community when these occur together are unclear. In this study we investigated the dynamics and drivers of phytoplankton biomass and community composition in the Pearl River plume-coastal upwelling system on the northern South China Sea shelf during summer. We found that phytoplankton biomass was lower in the plume than in upwelled water. Diatoms were the only dominant group in the upwelled water. In contrast, diatoms and Synechococcus were co-dominant in the plume, and the negative correlation between the …

Oxidation 1-Methyl Naphthalene Based On The Synergy Of Environmentally Persistent Free Radicals (Epfrs) And Pahs In Particulate Matter (Pm) Surface, Ajit Ghimire, Farhana Hasan, Xia Guan, Phillip Potter, Chuqi Guo, Slawo Lomnicki

Faculty Publications

Studies of the environmental fate through the interactions of particle-associated polycyclic aromatic hydrocarbons (PAHs) with environmentally persistent free radicals (EPFRs) are presented. The formation of PAHs and EPFRs typically occurs side by side during combustion-processes. The laboratory simulation studies of the model PAH molecule 1-Methylnaphthalene (1-MN) interaction with model EPFRs indicate a transformational synergy between these two pollutants due to mutual and matrix interactions. EPFRs, thorough its redox cycle result in the oxidation of PAHs into oxy-/hydroxy-PAHs. EPFRs have been shown before to produce OH radical during its redox cycle in aqueous media and this study has shown that produced …

Excluded Minors Are Almost Fragile Ii: Essential Elements, Nick Brettell, James Oxley, Charles Semple, Geoff Whittle

Faculty Publications

Let M be an excluded minor for the class of P-representable matroids for some partial field P, let N be a 3-connected strong P-stabilizer that is non-binary, and suppose M has a pair of elements {a,b} such that M﹨a,b is 3-connected with an N-minor. Suppose also that |E(M)|≥|E(N)|+11 and M﹨a,b is not N-fragile. In the prequel to this paper, we proved that M﹨a,b is at most five elements away from an N-fragile minor. An element e in a matroid M′ is N-essential if neither M′/e nor M′﹨e has an N-minor. In this paper, we prove …

The Excluded Minors For 2- And 3-Regular Matroids, Nick Brettell, James Oxley, Charles Semple, Geoff Whittle Nov 2023

The Excluded Minors For 2- And 3-Regular Matroids, Nick Brettell, James Oxley, Charles Semple, Geoff Whittle

Faculty Publications

The class of 2-regular matroids is a natural generalisation of regular and near-regular matroids. We prove an excluded-minor characterisation for the class of 2-regular matroids. The class of 3-regular matroids coincides with the class of matroids representable over the Hydra-5 partial field, and the 3-connected matroids in the class with a U2,5- or U3,5-minor are precisely those with six inequivalent representations over GF(5). We also prove that an excluded minor for this class has at most 15 elements.

Ab Initio Single-Neutron Spectroscopic Overlaps In Lithium Isotopes, G. H. Sargsyan, K. D. Launey, R. M. Shaffer, S. T. Marley, N. Dudeck, A. Mercenne, T. Dytrych, J. P. Draayer Nov 2023

Ab Initio Single-Neutron Spectroscopic Overlaps In Lithium Isotopes, G. H. Sargsyan, K. D. Launey, R. M. Shaffer, S. T. Marley, N. Dudeck, A. Mercenne, T. Dytrych, J. P. Draayer

Faculty Publications

We calculate single-neutron spectroscopic overlaps for lithium isotopes in the framework of the ab initio symmetry-adapted no-core shell model. We report the associated neutron-nucleus asymptotic normalization coefficients (ANCs) and spectroscopic factors (SFs) that are important ingredients in many reaction cross-section calculations. While spectroscopic factors have been traditionally extracted from experimental cross sections, their sensitivity on the type of reactions, the energy, and the underlying models point to the need for determining SFs from first-principle structure considerations. As illustrative examples, we present Li6+n, Li7+n, and Li8+n, and we show that the results are in a good agreement with those of other …

We report the first detection of the X-ray polarization of the bright transient Swift J1727.8−1613 with the Imaging X-ray Polarimetry Explorer. The observation was performed at the beginning of the 2023 discovery outburst, when the source resided in the bright hard state. We find a time- and energy-averaged polarization degree of 4.1% ± 0.2% and a polarization angle of 2.°2 ± 1.°3 (errors at 68% confidence level; this translates to ∼20σ significance of the polarization detection). This finding suggests that the hot corona emitting the bulk of the detected X-rays is elongated, rather than spherical. The X-ray polarization angle is …

The Nancy Grace Roman Space Telescope (Roman) is NASA’s next astrophysics flagship mission, expected to launch in late 2026. As one of Roman’s core community science surveys, the Galactic Bulge Time Domain Survey (GBTDS) will collect photometric and astrometric data for over 100 million stars in the Galactic bulge in order to search for microlensing planets. To assess the potential with which Roman can detect exoplanets via transit, we developed and conducted pixel-level simulations of transiting planets in the GBTDS. From these simulations, we predict that Roman will find between ∼60,000 and ∼200,000 transiting planets—over an order of magnitude more …

Widespread Sympatry In A Species-Rich Clade Of Marine Fishes (Carangoidei), Jessica R. Glass, Richard C. Harrington, Peter F. Cowman, Brant C. Faircloth, Thomas J. Near Nov 2023

Widespread Sympatry In A Species-Rich Clade Of Marine Fishes (Carangoidei), Jessica R. Glass, Richard C. Harrington, Peter F. Cowman, Brant C. Faircloth, Thomas J. Near

Faculty Publications

A universal paradigm describing patterns of speciation across the tree of life has been debated for decades. In marine organisms, inferring patterns of speciation using contemporary and historical patterns of biogeography is challenging due to the deficiency of species-level phylogenies and information on species' distributions, as well as conflicting relationships between species' dispersal, range size and co-occurrence. Most research on global patterns of marine fish speciation and biogeography has focused on coral reef or pelagic species. Carangoidei is an ecologically important clade of marine fishes that use coral reef and pelagic environments. We used sequence capture of 1314 ultraconserved elements …

Exposing The Error Hidden In Plain Sight: A Critique Of Calder's (1983) Group Selectionist Seed-Dispersal Hypothesis For Mistletoe “Mimicry” Of Host Plants, Kyle E. Harms, David M. Watson, Luis Y. Santiago-Rosario, Sarah Mathews Nov 2023

Exposing The Error Hidden In Plain Sight: A Critique Of Calder's (1983) Group Selectionist Seed-Dispersal Hypothesis For Mistletoe “Mimicry” Of Host Plants, Kyle E. Harms, David M. Watson, Luis Y. Santiago-Rosario, Sarah Mathews

Faculty Publications

Some mistletoe species (Loranthaceae) resemble their host plants to a striking degree. Various mechanisms have been proposed for the developmental origins of novel traits that cause mistletoes to appear similar to their hosts, as well as for the adaptive phenotypic evolution of such traits. Calder (1983) proposed a logically flawed group selectionist seed-dispersal hypothesis for mistletoes to resemble their hosts. Calder's (1983) hypothesis does not provide a viable potential explanation for mistletoe resemblance to hosts.

A Target Enrichment Probe Set For Resolving Phylogenetic Relationships In The Coffee Family, Rubiaceae, Laymon D. Ball, Ana M. Bedoya, Charlotte M. Taylor, Laura P. Lagomarsino

Faculty Publications

Premise: Rubiaceae is among the most species-rich plant families, as well as one of the most morphologically and geographically diverse. Currently available phylogenies have mostly relied on few genomic and plastid loci, as opposed to large-scale genomic data. Target enrichment provides the ability to generate sequence data for hundreds to thousands of phylogenetically informative, single-copy loci, which often leads to improved phylogenetic resolution at both shallow and deep taxonomic scales; however, a publicly accessible Rubiaceae-specific probe set that allows for comparable phylogenetic inference across clades is lacking. Methods: Here, we use publicly accessible genomic resources to identify putatively single-copy nuclear …

Environment And Host Genetics Influence The Biogeography Of Plant Microbiome Structure, Na Wei, Jiaqi Tan Nov 2023

Environment And Host Genetics Influence The Biogeography Of Plant Microbiome Structure, Na Wei, Jiaqi Tan

Faculty Publications

To understand how microbiota influence plant populations in nature, it is important to examine the biogeographic distribution of plant-associated microbiomes and the underlying mechanisms. However, we currently lack a fundamental understanding of the biogeography of plant microbiomes across populations and the environmental and host genetic factors that shape their distribution. Leveraging the broad distribution and extensive genetic variation in duckweeds (the Lemna species complex), we identified key factors that governed plant microbiome diversity and compositional variation geographically. In line with the microbial biogeography of free-living microbiomes, we observed higher bacterial richness in temperate regions relative to lower latitudes in duckweed …

Combining antiviral drugs with different mechanisms of action can help prevent the development of resistance by attacking the infectious agent through multiple pathways. Additionally, by using faster and more economical screening methods, effective synergistic drug candidates can be rapidly identified, facilitating faster paths to clinical testing. In this work, a rapid method was standardized to identify possible synergisms from drug combinations. We analyzed the possible reduction in the antiviral effective concentration of drugs already approved by the FDA, such as ivermectin (IVM), ribavirin (RIBA), and acyclovir (ACV) against Zika virus (ZIKV), Chikungunya virus (CHIKV), and herpes virus type 2 (HHV-2). …

Engaging with Kimberlé Crenshaw’s concept of intersectionality, the authors (re)turn to its genesis in critical race theory (CRT) and specifically, its forms of structural intersectionality, political intersectionality, and representational intersectionality. Discussing each form in relation to contemporary issues in sport that Black women and women of Color navigate, they argue that Crenshaw’s intersectionality provides additional compelling layers of engagement with existing intersectional scholarship and scholarship about activism in sport, invites structural and discursive change through intersectional policies and practice, and promotes coalition building toward intersectional racial justice in sport.
