Selenocysteine (Sec) is cotranslationally inserted into protein in response to UGA codons and is the 21st amino acid in the genetic code. However, the means by which Sec is synthesized in eukaryotes is not known. Herein, comparative genomics and experimental analyses revealed that the mammalian Sec synthase (SecS) is the previously identified pyridoxal phosphate-containing protein known as the soluble liver antigen. SecS required selenophosphate and Ophosphoseryl- tRNA [Ser]Sec as substrates to generate selenocysteyl-tRNA [Ser]Sec. Moreover, it was found that Sec was synthesized on the tRNA scaffold from selenide, ATP, and serine using tRNA [Ser]Sec, seryl-tRNA synthetase, Ophosphoseryl- tRNA …

Genetic Modification Of Host Acceptance By A Seed Beetle: Quasi-Natural Vs. Artificial Selection, Meagan Bridges, Jake Jones, Amberleigh Muller, Frank J. Messina
Biology Posters
Many plant-feeding insects use a fairly well-defined set of hosts, but are occasionally observed on an atypical host. The seed beetle Callosobruchus maculatus infests several grain legumes, especially Vigna spp. It has rarely been reported to attack lentil, a distant relative of its typical hosts (Credland, 1987). In three previous mass-selection experiments, we showed that larval survival in lentil increased rapidly after a bottleneck, from 70% in only 5-7 generations. Host shifts by insects may also require modification of egg-laying behavior. Initial assays confirmed that most C. maculatus females fail to recognize lentil as a potential host. We used both …

Pattern Of Genetic Recovery In Daphnia Populations Following Experimental Removal Of Fish, Jaewook Chung, Leigh C. Latta, Iv, Michael E. Pfrender
Biology Posters
The establishment and maintenance of high levels of genetic diversity is an important consideration for populations that have experienced recent demographic collapse. Populations that have undergone demographic contraction or have been recently established generally lack standing adaptive variation. The level of adaptive genetic variation is a key determinant of population persistence, especially in changing environments, since dramatic changes in environmental conditions or community composition may impose severe or novel selective pressures. We obtained data for nuclear markers and conducted a common-garden experiment to assess the current levels of molecular genetic variation. Our results suggest that in the approximately eight years …

Native And Exotic Plant Species Exhibit Similar Population Dynamics During Succession, Scott Meiners
Native And Exotic Plant Species Exhibit Similar Population Dynamics During Succession, Scott Meiners
Faculty Research & Creative Activity
A growing body of literature has led to the debate in invasion biology whether exotic species perform within communities differently than native taxa due to inherent advantages. To address this issue, the population dynamics of native and exotic plant species were assessed from a 48-year record of permanent plot data from the Hutcheson Memorial Forest Center (New Jersey, USA) to determine rate of increase, lag time, maximum frequency, and the year of peak frequency. Overall, native and exotic species exhibited very similar population dynamics. Rates of increase and length of lag times were similar between native and exotic taxa but …

Life Without Water: Expression Of Plant Lea Genes By An Anhydrobiotic Arthropod, Steven C. Hand, Dana Jones, Michael A. Menze, Trudy L. Witt
Faculty Research & Creative Activity
Anhydrobiotic animals protect cellular architecture and metabolic machinery in the dry state, yet the molecular repertoire supporting this profound dehydration tolerance is not fully understood. For the desiccation-tolerant crustacean, Artemia franciscana, we report differential expression of two distinct mRNAs encoding for proteins that share sequence similarities and structural features with late-embryogenesis abundant (LEA) proteins originally discovered in plants. Bioinformatic analyses support assignment of the LEA proteins from A. franciscana to group 3. This eucoelomate species is the most highly evolved animal for which LEA gene expression has been reported. It is becoming clear that an ensemble of micromolecules and macromolecules …

Alaska At The Crossroads Of Migration: Space-Based Ornithology, Jill L. Deppe, K Wessels, J A. Smith
Alaska At The Crossroads Of Migration: Space-Based Ornithology, Jill L. Deppe, K Wessels, J A. Smith
Faculty Research & Creative Activity
Understanding bird migration on a global scale is one of the most compelling and challenging problems of modern biology. Each year multitudes of migratory birds travel between breeding grounds in Alaska and wintering grounds in the Americas, Asia, and Australia. Here we present the conceptual framework for a spatially explicit, individual-based biophysical migration model driven by dynamic remote sensing observations of atmospheric and land surface conditions to simulate migration routes, timing, energy budgets, and probability of survival. Understanding temporal and spatial patterns of bird migration will provide insight into pressing conservation and human health issues related to this taxonomic group.

Over-Expression Of Udp-Glucose Pyrophosphorylase In Hybrid Poplar Affects Carbon Allocation, Heather Coleman, Thomas Canam, Kyu-Young Kang, David Ellis, Shawn Mansfield
Faculty Research & Creative Activity
The effects of the over-expression of the Acetobacter xylinum UDP-glucose pyrophosphorylase (UGPase) under the control of the tandem repeat Cauliflower Mosaic Virus promoter (2335S) on plant metabolism and growth were investigated in hybrid poplar (Populus alba3grandidentata). Transcript levels, enzyme activity, growth parameters, leaf morphology, structural and soluble carbohydrates, and soluble metabolite levels were quantified in both transgenic and wild-type trees. Transgenic 2335S::UGPase poplar showed impaired growth rates, displaying reduced height growth and stem diameter. Morphologically, 2335S::UGPase trees had elongated axial shoots, and leaves that were substantially smaller in size when compared with wild-type trees at equivalent developmental stages. Biochemical analysis …
Production Of Methanethiol And Volatile Sulfur Compounds By The Archaeon ‘‘Ferroplasma Acidarmanus’’, David Baumler, Kai Hung, Kwang Jeong, Charles Kaspar
Production Of Methanethiol And Volatile Sulfur Compounds By The Archaeon ‘‘Ferroplasma Acidarmanus’’, David Baumler, Kai Hung, Kwang Jeong, Charles Kaspar
Faculty Research & Creative Activity
Acidophiles are typically isolated from sulfaterich ecological niches yet the role of sulfur metabolism in their growth and survival is poorly defined. Studies of heterotrophically grown ‘‘Ferroplasma acidarmanus’’ showed that its growth requires a minimum of 100 mM of a sulfate-containing salt. Headspace gas analyses by GC/ MS determined that the volatile sulfur compound emitted by active ‘‘F. acidarmanus’’ cultures is methanethiol. In ‘‘F. acidarmanus’’ cultures grown either heterotrophically or chemolithotrophically, methanethiol was produced constitutively. Radiotracer studies with 35S-labeled methionine, cysteine, and sulfate showed that all three were used in methanethiol production. Additionally, 3H-labeled methionine was incorporated into methanethiol and …
On The Depth And Scale Of Metabolic Rate Variation: Scaling Of Oxygen Consumption Rates And Enzymatic Activity In The Class Cephalopoda (Mollusca), Brad A. Seibel
Biological Sciences Faculty Publications
Recent ecological theory depends, for predictive power, on the apparent similarity of metabolic rates within broad taxonomic or functional groups of organisms (e.g. invertebrates or ectotherms). Such metabolic commonality is challenged here, as I demonstrate more than 200-fold variation in metabolic rates independent of body mass and temperature in a single class of animals, the Cephalopoda, over seven orders of magnitude size range. I further demonstrate wide variation in the slopes of metabolic scaling curves. The observed variation in metabolism reflects differential selection among species for locomotory capacity rather than mass or temperature constraints. Such selection is highest among epipelagic …

Rapid Field Immunoassay For Detecting Antibody To Sin Nombre Virus In Deer Mice, Tony Schountz, Charles H. Calisher, Tiffany R. Richens, Audrey A. Rich, Jeffrey B. Doty, Mark T. Hughes, Barry J. Beaty
Biological Sciences Faculty Publications
We developed a 1-hour field enzyme immunoassay (EIA) for detecting antibody to Sin Nombre virus in deer mice (Peromyscus maniculatus). The assay specificity and sensitivity were comparable to those of a standard EIA. This test will permit identification of rodents with antibody to this and perhaps other hantaviruses.

In Silico Analysis Of Terpene Synthase Genes In Arabidopsis Thaliana, Sam Zwenger, Chhandak Basu
Biological Sciences Faculty Publications
Terpenes are defense chemicals found in wide groups of plants. Terpenoids play a large role in plant development and stress response. The terpene synthase family comprises a diverse set of genes, all which contribute to production of terpenoids. We have used tools of bioinformatics and performed an in silico analysis of developmental and tissue specific terpene synthase gene expression in Arabidopsis thaliana, as well as those expressed due to biotic and abiotic environmental stimuli. Using software tools from Genevestigator, a powerful microarray analyzer, we used multiple tool sets to better understand terpene synthase expression in Arabidopsis, which will hopefully open …

Roman L. Hruska U.S. Meat Animal Research Center: Reports
This study compares the meat composition of the offspring from boars produced by somatic cell nuclear transfer (n = 4) to that of the offspring from conventionally produced boars (n = 3). In total, 89 commercial gilts were artificially inseminated and 61 progressed to term and farrowed. All of the resulting piglets were housed and raised identically under standard commercial settings and slaughtered upon reaching market weight. Loin samples were taken from each slaughtered animal and shipped offsite for meat composition analysis. In total, loin samples from 404 animals (242 from offspring of clones and 162 from controls) …

Spirobicyclic Diamines. Part 3: Synthesis And Metal Complexation Of Proline-Derived [4,4]-Spirodiamines., Fintan Kelleher, Sinead Kelly, Vickie Mckee
Articles
The syntheses of racemic and homochiral [4.4]-spirolactams, starting from L-proline, in good yields are described. Reduction of the lactam carbonyl group of spirolactams, containing chiral substituents on the lactam nitrogen, with lithium aluminium hydride, gives a series of homochiral [4.4]-spirodiamines. The crystal structure of one of these spirodiamines on complexation with zinc chloride was obtained. Interestingly it showed a hydrogen-bonded dimeric structure, where the monomers are diastereoisomeric diamines.

Synthesis And Characterisation Of Tetra-Tetrazole Macrocycles, Andrew Bond, Adrienne Fleming, Fintan Kelleher, John Mcginley, Vipa Prajapati, Signe Skovsgaard
Articles
The syntheses of tetra-tetrazole macrocycles, containing two bis-tetrazole units linked by a variety of alkyl chain lengths from four to eight carbons, are described. The crystal structures of three of these derivatives are reported, and the molecular conformation in the solid state is compared to that of one previously reported tetra-tetrazole macrocycle and to other bis- and tris(tetrazole)benzene structures. The macrocycle conformation is influenced by the length of the alkyl chain linker, the relative orientation of the tetrazole rings on the benzene ring, and by intermolecular interactions. In the macrocycles based on 1,2-bis(tetrazole)benzene, the adjacent tetrazole rings on the benzene …
