Host-Induced Silencing Of Fusarium Culmorum Genes Protects Wheat From Infection, Wanxin Chen, Christine Kastner, Daniela Nowara, Ely Oliveira-Garcia, Twan Rutten, Yusheng Zhao, Holger B. Deising, Jochen Kumlehn, Patrick Schweizer

Faculty Publications

Plants producing antisense or double-stranded RNA molecules that target specific genes of eukaryotic pests or pathogens can become protected from their attack. This beneficial effect was also reported for plant-fungus interactions and is believed to reflect uptake of the RNAs by the fungus via an as yet unknown mechanism, followed by target gene silencing. Here we report that wheat plants pre-infected with Barley stripe mosaic virus (BSMV) strains containing antisense sequences against target genes of the Fusarium head blight (FHB) fungus F. culmorum caused a reduction of corresponding transcript levels in the pathogen and reduced disease symptoms. Stable transgenic wheat …

Chronic Disease Self-Management And Behavior Change Attitudes In Older Adults: A Mixed-Method Feasibility Study, Kimberly A. Sell, Elaine J. Amella, Martina Mueller, Jeannette Andrews Phd, Rn, Faan, Joy Wachs

Faculty Publications

The population of older adults with chronic disease is increasing, yet little is known about their perception of chronic disease and self-management. To develop successful and sustainable chronic disease self-management interventions in the older adult population, health care providers must first understand older adults’ attitudes toward health status and behavior change. This pilot study was conducted to determine the feasibility of the study design. The purpose of this pilot study was to assess the appropriateness of using a mixed-methods research design to investigate Appalachian older adult’s attitude toward the chronic disease experience and health behavior change. A convergent, parallel mixed-method …

Examining The Effects Of Chromatic Aberration, Object Distance, And Eye Shape On Image-Formation In The Mirror-Based Eyes Of The Bay Scallop Argopecten Irradians, Daniel Isaac Speiser, Yakir Luc Gagnon, Raghav K. Chhetri, Amy L. Oldenburg, Sönke Johnsen Aug 2016

Examining The Effects Of Chromatic Aberration, Object Distance, And Eye Shape On Image-Formation In The Mirror-Based Eyes Of The Bay Scallop Argopecten Irradians, Daniel Isaac Speiser, Yakir Luc Gagnon, Raghav K. Chhetri, Amy L. Oldenburg, Sönke Johnsen

Faculty Publications

The eyes of scallops form images using a concave spherical mirror and contain two separate retinas, one layered on top of the other. Behavioral and electrophysiological studies indicate that the images formed by these eyes have angular resolutions of about 2°. Based on previous ray-tracing models, it has been thought that the more distal of the two retinas lies near the focal point of the mirror and that the proximal retina, positioned closer to the mirror at the back of the eye, receives light that is out-of-focus. Here, we propose three mechanisms through which both retinas may receive focused light: …

Caustic Structures And Detectability Of Circumbinary Planets In Microlensing, Jacob K. Luhn, Matthew T. Penny, B. Scott Gaudi Aug 2016

Caustic Structures And Detectability Of Circumbinary Planets In Microlensing, Jacob K. Luhn, Matthew T. Penny, B. Scott Gaudi

Faculty Publications

Recent discoveries of circumbinary planets in Kepler data show that there is a viable channel of planet formation around binary main-sequence stars. Motivated by these discoveries, we have investigated the caustic structures and detectability of circumbinary planets in microlensing events. We have produced a suite of animations of caustics as a function of the projected separation and angle of the binary host to efficiently explore caustic structures over the entire circumbinary parameter space. Aided by these animations, we have derived a semi-empirical analytic expression for the location of planetary caustics, which are displaced in circumbinary lenses relative to those of …

© 2016 The Authors. The Journal of Physiology © 2016 The Physiological Society Key points: Maternal obesity reduces adipogenic progenitor density in offspring adipose tissue. The ability of adipose tissue expansion in the offspring of obese mothers is limited and is associated with metabolic dysfunction of adipose tissue when challenged with a high-fat diet. Maternal obesity induces DNA demethylation in the promoter of zinc finger protein 423, which renders progenitor cells with a high adipogenic capacity. Maternal obesity demonstrates long-term effects on the adipogenic capacity of progenitor cells in offspring adipose tissue, demonstrating a developmental programming effect.

Attenuation Of Pamp-Triggered Immunity In Maize Requires Down-Regulation Of The Key Β-1,6-Glucan Synthesis Genes Kre5 And Kre6 In Biotrophic Hyphae Of Colletotrichum Graminicola, Ely Oliveira-Garcia, Holger B. Deising Aug 2016

Attenuation Of Pamp-Triggered Immunity In Maize Requires Down-Regulation Of The Key Β-1,6-Glucan Synthesis Genes Kre5 And Kre6 In Biotrophic Hyphae Of Colletotrichum Graminicola, Ely Oliveira-Garcia, Holger B. Deising

Faculty Publications

In plants, pathogen defense is initiated by recognition of pathogen-associated molecular patterns (PAMPs) via plasma membrane-localized pattern-recognition receptors (PRRs). Fungal structural cell wall polymers such as branched β-glucans are essential for infection structure rigidity and pathogenicity, but at the same time represent PAMPs. Kre5 and Kre6 are key enzymes in β-1,6-glucan synthesis and formation of branch points of the β-glucan network. In spite of the importance of branched β-glucan for hyphal rigidity and plant–fungus interactions, neither the role of KRE5 and KRE6 in pathogenesis nor mechanisms allowing circumventing branched β-glucan-triggered immune responses are known. We functionally characterized KRE5 and KRE6 …

Spatiotemporal Distributions Of Sr And Ba Along An Estuarine River With A Large Salinity Gradient To The Gulf Of Mexico, Songjie He, Y. Jun Xu Aug 2016

Spatiotemporal Distributions Of Sr And Ba Along An Estuarine River With A Large Salinity Gradient To The Gulf Of Mexico, Songjie He, Y. Jun Xu

Faculty Publications

Strontium and barium to calcium ratios are often used as proxies for tracking animal movement across salinity gradients. Many estuarine rivers face saltwater intrusion due to sea level rise, potentially causing changes in mobility and distribution of these metals upstream. From May 2013 to August 2015, monthly water samples were collected and in-situ measurements were performed at six sites along an estuary strongly affected by saltwater intrusion, the Calcasieu River, with salinity ranging from 0.02 to 29.50 Parts Per Thousand (ppt). Results showed that the total Sr concentration and the Sr/Ca ratio both increased significantly with increasing salinity. The average …

The Social Structure Of Golfo Dulce Bottlenose Dolphins (Tursiops Truncatus) And The Influence Of Behavioural State, Kelsey Moreno, Alejandro Acevedo-Gutierrez Aug 2016

The Social Structure Of Golfo Dulce Bottlenose Dolphins (Tursiops Truncatus) And The Influence Of Behavioural State, Kelsey Moreno, Alejandro Acevedo-Gutierrez

Faculty Publications

Ecological factors such as habitat and food availability affect the social structure of bottlenose dolphins (Tursiops spp.). Here, we describe the social structure of bottlenose dolphins (T. truncatus) in Golfo Dulce, Costa Rica, a semi-enclosed, fjord-like tropical embayment resembling a pelagic system. We also examine behaviour-linked social strategies by comparing social structure relative to behavioural state: feeding versus non-feeding. We analysed 333 sightings over 210 days from boat-based surveys. Despite the uniqueness of the area, the 47 analysed adults had a social structure similar to other populations: a well-differentiated fission-fusion society with sex-specific patterns of associations and aggression. These results …

Eight Reasons Women Stay In Abusive Relationships, Jason B. Whiting Jul 2016

Eight Reasons Women Stay In Abusive Relationships, Jason B. Whiting

Faculty Publications

When NFL linebacker Ray Rice knocked his fiancée Janay Palmer unconscious in an elevator in 2014, it didn't initially get much attention. He was accused of domestic violence and suspended for two games. After a few weeks he was formally charged, but he and Palmer were married the next day. However, when a security video of the event surfaced, it quickly went viral. Watching Palmer get knocked out and roughly dragged out of the elevator by Rice had a powerful effect on viewers. The waves of outrage that followed caused the NFL to scramble to increase their punishment of Ray …

Invited Review: Mesenchymal Progenitor Cells In Intramuscular Connective Tissue Development, Z. G. Miao, L. P. Zhang, X. Fu, Q. Y. Yang, M. J. Zhu, M. V. Dodson, M. Du Jul 2016

Invited Review: Mesenchymal Progenitor Cells In Intramuscular Connective Tissue Development, Z. G. Miao, L. P. Zhang, X. Fu, Q. Y. Yang, M. J. Zhu, M. V. Dodson, M. Du

Faculty Publications

© The Animal Consortium 2015. The abundance and cross-linking of intramuscular connective tissue contributes to the background toughness of meat, and is thus undesirable. Connective tissue is mainly synthesized by intramuscular fibroblasts. Myocytes, adipocytes and fibroblasts are derived from a common pool of progenitor cells during the early embryonic development. It appears that multipotent mesenchymal stem cells first diverge into either myogenic or non-myogenic lineages; non-myogenic mesenchymal progenitors then develop into the stromal-vascular fraction of skeletal muscle wherein adipocytes, fibroblasts and derived mesenchymal progenitors reside. Because non-myogenic mesenchymal progenitors mainly undergo adipogenic or fibrogenic differentiation during muscle development, strengthening progenitor …

Three Distinct Glutamate Decarboxylase Genes In Vertebrates, Brian P. Grone, Karen P. Maruska Jul 2016

Three Distinct Glutamate Decarboxylase Genes In Vertebrates, Brian P. Grone, Karen P. Maruska

Faculty Publications

Gamma-aminobutyric acid (GABA) is a widely conserved signaling molecule that in animals has been adapted as a neurotransmitter. GABA is synthesized from the amino acid glutamate by the action of glutamate decarboxylases (GADs). Two vertebrate genes, GAD1 and GAD2, encode distinct GAD proteins: GAD67 and GAD65, respectively. We have identified a third vertebrate GAD gene, GAD3. This gene is conserved in fishes as well as tetrapods. We analyzed protein sequence, gene structure, synteny, and phylogenetics to identify GAD3 as a homolog of GAD1 and GAD2. Interestingly, we found that GAD3 was lost in the hominid lineage. Because of the importance …

This review explores characteristics of facial primes employed in priming studies of racial prejudice and stereotyping. It addresses the role of perceptual, cue-based processing of visual stimuli characteristics in altering racial typicality, and the effects of different moderators. The authors document the nature of variability in primes and moderators used in priming studies (N = 96) up to 2009. Methodological and conceptual implications are discussed, along with gaps in the field. Better control over facial primes employed, more accuracy in reporting and open access to procedural information are suggested in an effort to improve the state of racial priming …

Phosphogenesis Associated With The Shuram Excursion: Petrographic And Geochemical Observations From The Ediacaran Doushantuo Formation Of South China, Huan Cui, Shuhai Xiao, Chuanming Zhou, Yongbo Peng, Alan J. Kaufman, Rebecca E. Plummer

Faculty Publications

© 2016 Elsevier B.V. The Ediacaran Period witnessed one of the largest phosphogenic events in Earth's history. Coincidently, some phosphorite deposits in South China are associated with the largest-known carbon isotope negative excursion (i.e., Shuram Excursion), suggesting an intimate coupling of the biogeochemical carbon and phosphorous cycles. However, the geomicrobiological linkage between these anomalies remain poorly understood. In this study, we investigated the phosphorite samples from the uppermost Doushantuo Formation in South China. Carbon isotope compositions of authigenic calcite cements and nodules in the phosphorites are as low as –34‰ (VPDB). Petrographic and geochemical investigations indicate that the 13C-depleted carbonates …

Mg/Al ratio plays a significant role for anion adsorption by Mg/Al-layered double hydroxides (Mg/Al-LDHs) modified biochar. In this study, Mg/Al-LDHs biochar with different Mg/Al ratios (2, 3, 4) were prepared by co-precipitation for phosphate removal from aqueous solution. Factors on phosphate adsorption including Mg/Al ratio, pH, and the presence of other inorganic anions were investigated through batch experiments. Increasing Mg/Al ratio in the Mg/Al-LDHs biochar composites generally enhanced phosphate adsorption with Langmuir adsorption maximum calculated at 81.83 mg phosphorous (P) per gram of 4:1 Mg/Al-LDHs biochar at pH 3.0. The adsorption process was best described by the pseudo-second-order kinetic model. …

© 2016 The Author(s). Light is known to excite photosensitizers (PS) to produce cytotoxic reactive oxygen species (ROS) in the presence of oxygen. This modality is attractive for designing control measures against animal diseases and pests. Many PS have a proven safety record. Also, the ROS cytotoxicity selects no resistant mutants, unlike other drugs and pesticides. Photodynamic therapy (PDT) refers to the use of PS as light activable tumoricides, microbicides and pesticides in medicine and agriculture. Here we describe "photodynamic vaccination" (PDV) that uses PDT-inactivation of parasites, i.e. Leishmania as whole-cell vaccines against leishmaniasis, and as a universal carrier to …

Pathogens inflict a wide variety of disease manifestations on their hosts, yet the impacts of disease on the behaviour of infected hosts are rarely studied empirically and are seldom accounted for in mathematical models of transmission dynamics. We explored the potential impacts of one of the most common disease manifestations, fever, on a key determinant of pathogen transmission, host mobility, in residents of the Amazonian city of Iquitos, Peru. We did so by comparing two groups of febrile individuals (dengue-positive and dengue-negative) with an afebrile control group. A …

Geospatial Modeling Approach To Monument Construction Using Michigan From A.D. 1000–1600 As A Case Study, Meghan L. Howey, Michael W. Palace, Crystal H. Mcmichael Jul 2016

Geospatial Modeling Approach To Monument Construction Using Michigan From A.D. 1000–1600 As A Case Study, Meghan L. Howey, Michael W. Palace, Crystal H. Mcmichael

Faculty Publications

Building monuments was one way that past societies reconfigured their landscapes in response to shifting social and ecological factors. Understanding the connections between those factors and monument construction is critical, especially when multiple types of monuments were constructed across the same landscape. Geospatial technologies enable past cultural activities and environmental variables to be examined together at large scales. Many geospatial modeling approaches, however, are not designed for presence-only (occurrence) data, which can be limiting given that many archaeological site records are presence only. We use maximum entropy modeling (MaxEnt), which works with presence-only data, to predict the distribution of monuments …

Alone In The Crowd: Appropriated Text And Subjectivity In The Work Of Rirkrit Tiravanija, Liz Linden

Faculty Publications

The practice of Thai artist Rirkrit Tiravanija is perhaps the best-known exemplar of relational aesthetics, a distinction first made by Nicholas Bourriaud and affirmed in the writings of many subsequent art critics; but the critical focus on the interactive aspect of his works has tended to rely on utopian modes of community engagement, which ignore Tiravanija's strategic deployment of relational, interactive structures to implicate the viewer, publicly, in problematic political positions. Tiravanija commonly uses appropriation in his artworks as a way of exposing viewer's biases and this paper focuses specifically on his use of appropriated text to explore divided subjectivities …

© 2015 Wiley Periodicals, Inc. Knowledge concerning mechanisms that control proliferation and differentiation of preadipocytes is essential to our understanding of adipocyte hyperplasia and the development of obesity. Evidence has shown that temporal regulation of mitogen-activated protein kinase (MAPK) phosphorylation and dephosphorylation is critical for coupling extracellular stimuli to cellular growth and differentiation. Using differentiating 3T3-L1 preadipocytes as a model of adipocyte hyperplasia, we examined a role for dual-specificity phosphatase 1 (DUSP1) on the timely modulation of MAPK signaling during states of growth arrest, proliferation, and differentiation. Using real-time reverse transcription PCR (qRT-PCR), we report that DUSP1 is induced during …

The Contribution Of The Pineal Gland On Daily Rhythms And Masking In Diurnal Grass Rats, Arvicanthis Niloticus, Dorela D. Shuboni, Amna A. Agha, Thomas K. H. Groves, Andrew J. Gall

Faculty Publications

Melatonin is a hormone rhythmically secreted at night by the pineal gland in vertebrates. In diurnal mammals, melatonin is present during the inactive phase of the rest/activity cycle, and in primates it directly facilitates sleep and decreases body temperature. However, the role of the pineal gland for the promotion of sleep at night has not yet been studied in non-primate diurnal mammalian species. Here, the authors directly examined the hypothesis that the pineal gland contributes to diurnality in Nile grass rats by decreasing activity and increasing sleep at night, and that this could occur via effects on circadian mechanisms or …
