Feeding Ecology Of Three Coastal Shark Species In The Northwest Gulf Of Mexico, Jeffrey D. Plumlee, R. J.David Wells May 2016

Feeding Ecology Of Three Coastal Shark Species In The Northwest Gulf Of Mexico, Jeffrey D. Plumlee, R. J.David Wells

Faculty Publications

The feeding ecology of 3 coastal shark species-Atlantic sharpnose Rhizoprionodon terraenovae, bonnethead Sphyrna tiburo, and blacktip Carcharhinus limbatus shark-was examined in the northwest Gulf of Mexico (GOM). A total of 601 sharks (305 Atlantic sharpnose, 239 bonnethead, and 57 blacktip) were collected over 2 yr from recreational anglers in Galveston, TX. All individuals had stomach contents examined and a subset (50 Atlantic sharpnose, 50 bonnethead, and 36 blacktip sharks) was analyzed for stable isotopes (carbon, nitrogen, and sulfur) in muscle tissue, revealing short-term and long-term feeding strategies. Both blacktip and Atlantic sharpnose shark stomach contents consisted of teleost fishes with …

Insights From The Pollination Drop Proteome And The Ovule Transcriptome Of Cephalotaxus At The Time Of Pollination Drop Production, Cary Pirone-Davies, Natalie Prior, Patrick Von Aderkas, Derek Smith, Darryl Hardie, William E. Friedman, Sarah Mathews

Faculty Publications

© The Author 2016. Published by Oxford University Press on behalf of the Annals of Botany Company. Background and Aims Many gymnosperms produce an ovular secretion, the pollination drop, during reproduction. The drops serve as a landing site for pollen, but also contain a suite of ions and organic compounds, including proteins, that suggests diverse roles for the drop during pollination. Proteins in the drops of species of Chamaecyparis, Juniperus, Taxus, Pseudotsuga, Ephedra and Welwitschia are thought to function in the conversion of sugars, defence against pathogens, and pollen growth and development. To better understand gymnosperm pollination biology, the pollination …

Faculty Publications

© 2016 American Chemical Society. Previous characterization of hemophores from Serratia marcescens (HasAs), Pseudomonas aeruginosa (HasAp), and Yersinia pestis (HasAyp) showed that hemin binds between two loops, where it is axially coordinated by H32 and Y75. The Y75 loop is structurally conserved in all three hemophores and harbors conserved ligand Y75. The other loop contains H32 in HasAs and HasAp, but a noncoordinating Q32 in HasAyp. The H32 loop in apo-HasAs and apo-HasAp is in an open conformation, which places H32 about 30 Å from the hemin-binding site. Hence, hemin binding onto the Y75 loop of HasAs or HasAp triggers …

Comprehensive Analysis And Expression Profiling Of The Oslax And Osabcb Auxin Transporter Gene Families In Rice (Oryza Sativa) Under Phytohormone Stimuli And Abiotic Stresses, Chenglin Chai, Prasanta K. Subudhi May 2016

Comprehensive Analysis And Expression Profiling Of The Oslax And Osabcb Auxin Transporter Gene Families In Rice (Oryza Sativa) Under Phytohormone Stimuli And Abiotic Stresses, Chenglin Chai, Prasanta K. Subudhi

Faculty Publications

The plant hormone auxin regulates many aspects of plant growth and developmental processes. Auxin gradient is formed in plant as a result of polar auxin transportation by three types of auxin transporters such as OsLAX, OsPIN, and OsABCB. We report here the analysis of two rice auxin transporter gene families, OsLAX and OsABCB, using bioinformatics tools, publicly accessible microarray data, and quantitative RT-PCR. There are 5 putative OsLAXs and 22 putative OsABCBs in rice genome, which were mapped on 8 chromosomes. The exon-intron structure of OsLAX genes and properties of deduced proteins were relatively conserved within grass family, while that …

Streptomyces Coelicolor Xdhr Is A Direct Target Of (P)Ppgpp That Controls Expression Of Genes Encoding Xanthine Dehydrogenase To Promote Purine Salvage, Smitha Sivapragasam, Anne Grove May 2016

Streptomyces Coelicolor Xdhr Is A Direct Target Of (P)Ppgpp That Controls Expression Of Genes Encoding Xanthine Dehydrogenase To Promote Purine Salvage, Smitha Sivapragasam, Anne Grove

Faculty Publications

© 2016 John Wiley & Sons Ltd. The gene encoding Streptomyces coelicolor xanthine dehydrogenase regulator (XdhR) is divergently oriented from xdhABC, which encodes xanthine dehydrogenase (Xdh). Xdh is required for purine salvage pathways. XdhR was previously shown to repress xdhABC expression. We show that XdhR binds the xdhABC-xdhR intergenic region with high affinity (Kd ∼ 0.5 nM). DNaseI footprinting reveals that this complex formation corresponds to XdhR binding the xdhR gene promoter at two adjacent sites; at higher protein concentrations, protection expands to a region that overlaps the transcriptional and translational start sites of xdhABC. While substrates for Xdh have …

Message from President: With every change of regime comes a predictable if welcome discussion of the structure of higher education. In Louisiana, with its four systems and its Board of Regents, this “conversation,” as administrators like to call it, usually centers on either the rearrangement of campuses or the consolidation of administrative units or the reduction of overhead. Occasionally, the more optimistic among us hope that, during regime turnover, the membership of management boards might change (with the good effect of allowing current board members to resume their proper role, that of wealthy heirs ironically professing the gospel of the …

The Cytoplasmic Carbonic Anhydrases Βca2 And Βca4 Are Required For Optimal Plant Growth At Low Co2, Robert J. Dimario, Jennifer C. Quebedeaux, David J. Longstreth, Maheshi Dassanayake, Monica M. Hartman, James V. Moroney May 2016

The Cytoplasmic Carbonic Anhydrases Βca2 And Βca4 Are Required For Optimal Plant Growth At Low Co2, Robert J. Dimario, Jennifer C. Quebedeaux, David J. Longstreth, Maheshi Dassanayake, Monica M. Hartman, James V. Moroney

Faculty Publications

© 2016 American Society of Plant Biologists. All Rights Reserved. Carbonic anhydrases (CAs) are zinc metalloenzymes that interconvert CO2 and HCO3-. In plants, both α-and β-type CAs are present. We hypothesize that cytoplasmic bCAs are required to modulate inorganic carbon forms needed in leaf cells for carbonrequiring reactions such as photosynthesis and amino acid biosynthesis. In this report, we present evidence that βCA2 and βCA4 are the two most abundant cytoplasmic CAs in Arabidopsis (Arabidopsis thaliana) leaves. Previously, βCA4 was reported to be localized to the plasma membrane, but here, we show that two forms of βCA4 are expressed in …

New Compartment Model Analysis Of Lean-Mass And Fat-Mass Growth With Overfeeding, Dmytro Shumilov, Steven B. Heymsfield, Leanne M. Redman, Kesava Kalluri, Joyoni Dey May 2016

New Compartment Model Analysis Of Lean-Mass And Fat-Mass Growth With Overfeeding, Dmytro Shumilov, Steven B. Heymsfield, Leanne M. Redman, Kesava Kalluri, Joyoni Dey

Faculty Publications

Objectives: Mathematical models of lean- and fat-mass growth with diet are useful to help describe and potentially predict the fat- and lean-mass change with different diets as a function of consumed protein and fat calories. Most of the existing models do not explicitly account for interdependence of fat-mass on the lean-mass and vice versa. The aim of this study was to develop a new compartmental model to describe the growth of lean and fat mass depending on the input of dietary protein and fat, and accounting for the interdependence of adipose tissue and muscle growth. Methods: The model was fitted …

Lectins from dietary plants have been shown to enhance drug absorption in the gastrointestinal tract of rats, be transported trans-synaptically as shown by tracing of axonal and dendritic paths, and enhance gene delivery. Other carbohydrate-binding protein toxins are known to traverse the gut intact in dogs. Post-feeding rhodamine- or TRITC-tagged dietary lectins, the lectins were tracked from gut to dopaminergic neurons (DAergic-N) in transgenic Caenorhabditis elegans (C. elegans) [egIs1(Pdat-1:GFP)] where the mutant has the green fluorescent protein (GFP) gene fused to a dopamine transport protein gene …

Faculty Publications

© 2016 John Wiley & Sons Ltd/CNRS. Although theoretical models have demonstrated that predator-prey population dynamics can depend critically on age (stage) structure and the duration and variability in development times of different life stages, experimental support for this theory is non-existent. We conducted an experiment with a host-parasitoid system to test the prediction that increased variability in the development time of the vulnerable host stage can promote interaction stability. Host-parasitoid microcosms were subjected to two treatments: Normal and High variance in the duration of the vulnerable host stage. In control and Normal-variance microcosms, hosts and parasitoids exhibited distinct population …

Competition-Mediated Feedbacks In Experimental Multispecies Epizootics, Tad Dallas, Richard J. Hall, John M. Drake

Faculty Publications

© 2016 by the Ecological Society of America. Competition structures ecological communities and alters host-pathogen interactions. In environmentally transmitted pathogens, an infection-resistant competitor may influence infection dynamics in a susceptible species through the negative impacts of competition (e.g., by reducing host density or causing nutritional stress that increases susceptibility to infection) and/or the positive impacts of reducing transmission efficiency (e.g., by removing environmental pathogen stages). Thus, a non-susceptible competitor may enhance, reduce, or have no net effect on susceptible host density and infection prevalence. Here, we couple an epidemiological model with experimental epidemics to test how resource competition with a …

Gene Family Expansions In Aphids Maintained By Endosymbiotic And Nonsymbiotic Traits, Rebecca P. Duncan, Honglin Feng, Douglas M. Nguyen, Alex C.C. Wilson

Faculty Publications

Facilitating the evolution of new gene functions, gene duplication is a major mechanism driving evolutionary innovation. Gene family expansions relevant to host/symbiont interactions are increasingly being discovered in eukaryotes that host endosymbiotic microbes. Such discoveries entice speculation that gene duplication facilitates the evolution of novel, endosymbiotic relationships. Here, using a comparative transcriptomic approach combined with differential gene expression analysis, we investigate the importance of endosymbiosis in retention of amino acid transporter paralogs in aphid genomes. To pinpoint the timing of amino acid transporter duplications we inferred gene phylogenies for five aphid species and three outgroups. We found that while some …

Faculty Publications

High hydrostatic pressure (HHP) has been used to pre-condition embryos before essential, yet potentially detrimental procedures such as cryopreservation. However, the mechanisms for HHP are poorly understood. We treated bovine blastocysts with three different HHP (40, 60 and 80 MPa) in combination with three recovery periods (0, 1 h, 2 h post HHP). Re-expansion rates were significantly higher at 40 and 60 but lower at 80 MPa after vitrification-warming in the treated groups than controls. Microarray analysis revealed 399 differentially expressed transcripts, representing 254 unique genes, among different groups. Gene ontology analysis indicated that HHP at 40 and 60 MPa …

Message from President: This season of political campaigns, in which every candidate tries to be universally nice to everyone while also mounting a universal attack against all enemies, brings to mind the strange link between niceness and authoritarianism. In Louisiana, a state with a royalist heritage (whether the French or the Spanish monarchies) and a state in which a preoccupation with etiquette and sociability blunts the painful recognition of a long history of disappointments, losses, failures, exclusions, and disasters, the linkage between sugary sweetness and acidic repression affects almost everything, whether the reluctance to speak out against social ills such …

© 2015 Elsevier B.V. and Société Française de Biochimie et Biologie Moléculaire (SFBBM). Aims Exposure to human adenovirus Ad36 is causatively and correlatively linked with better glycemic control in animals and humans, respectively. Although the anti-hyperglycemic property of Ad36 may offer some therapeutic potential, it is impractical to use an infectious agent for therapeutic benefit. Cell-based studies identified that Ad36 enhances cellular glucose disposal via its E4orf1 protein. Ability to improve glycemic control in vivo is a critical prerequisite for further investigating the therapeutic potential of E4orf1. Therefore, the aim of this study was to determine the ability of E4orf1 …

Objective To examine change in county-level adult obesity prevalence between 2004 and 2009 and identify associated community characteristics. Methods Change in county-level adult (≥20 years) obesity prevalence was calculated for a 5-year period (2004-2009). Community measures of economic, healthcare, recreational, food environment, population structure, and education contexts were also calculated. Regression analysis was used to assess community characteristics associated (p< 0.01) with change in adult obesity prevalence. Results Mean±SD change in obesity prevalence was 5.1±2.4%. Obesity prevalence decreased in 1.4% (n = 44) and increased in 98% (n = 3,060) of counties from 2004-2009. Results showed that both baseline levels and increases in physically inactive adults were associated with greater increases in obesity prevalence, while baseline levels of and increases in physician density and grocery store/supercenter density were related to smaller increases in obesity rates. Baseline levels of the Hispanic population share were negatively linked to changing obesity levels, while places with greater Hispanic population growth saw greater increases in obesity. Conclusions Most counties in the U.S. experienced increases in adult obesity prevalence from 2004 to 2009. Findings suggest that community-based interventions targeting adult obesity need to incorporate a range of community factors, such as levels of physical inactivity, access to physicians, availability of food outlets, and ethnic/racial population composition.
