Genetic Characterization And Genome-Wide Association Mapping For Dwarf Bunt Resistance In Bread Wheat Accessions From The Usda National Small Grains Collection, Tyler Gordon, Rui Wang, David Hole, Harold Bockelman, J. Michael Bonman, Jianli Chen

Plants, Soils, and Climate Faculty Publications

Key message

Dwarf bunt-resistant bread wheat accessions and SNP markers associated with DB resistance identified in this study are valuable resources for characterization and deployment of DB resistance in bread wheat.

Abstract

Dwarf bunt (DB), caused by Tilletia controversa J.G. Kühn, can significantly reduce grain yield and quality on autumn-sown wheat in regions with prolonged snow cover. DB can be managed with the use of resistant cultivars. The objectives of the present study were to characterize DB resistance in a large set of bread wheat accessions from the National Small Grains Collection and use a genome-wide association study approach to …

Structural And Functional Characterization Of Sulfonium Carbon-Oxygen Hydrogen Bonding In The Deoxyamino Sugar Methyltransferase Tyim1, Robert J. Fick, Scott Horowitz, Brandon G. Mcdole, Mary C. Clay, Ryan A. Mehl, Hashim M. Al-Hashimi, Steve Scheiner, Raymond C. Trievel

Chemistry and Biochemistry Faculty Publications

The N-methyltransferase TylM1 from Streptomyces fradiae catalyzes the final step in the biosynthesis of the deoxyamino sugar mycaminose, a substituent of the antibiotic tylosin. The high-resolution crystal structure of TylM1 bound to the methyl donor S-adenosylmethionine (AdoMet) illustrates a network of carbon-oxygen (CH•••O) hydrogen bonds between the substrate’s sulfonium cation and residues within the active site. These interactions include hydrogen bonds between the methyl and methylene groups of the AdoMet sulfonium cation and the hydroxyl groups of Tyr14 and Ser120 in the enzyme. To examine the functions of these interactions, we generated Tyr14 to phenylalanine (Y14F) and Ser120 to alanine …

Genomic Variation Of Introduced Salvinia Minima In Southeastern United States, Carol A. Rowe, Donald P. Hauber, Paul G. Wolf

Ecology Center Publications

Common salvinia, Salvinia minima Baker (Salviniaceae), is a small, floating aquatic fern native to Central and South America that has invaded fresh water bodies in southeastern United States since the 1930s. We examined genetic variation across much of the introduced range of this species in the United States using codominant RAD-seq markers. Data from over 600 variable loci showed a reduction in heterozygosity from east to west in addition to a corresponding trend in assignment of samples to one of two genetic groups. Our data are consistent with previous published work and with the hypothesis that common salvinia had a …

Resilience In Quaking Aspen: Recent Advances And Future Needs, Paul C. Rogers, C. Eisenberg, S. Clair

Wildland Resources Faculty Publications

Quaking Aspen (Populus tremuloides) sustainability is a topic of intense interest in forest ecology. Reports range from declines to persisting or increasing coverage in some areas. Moreover, there is little agreement on ultimate factors driving changes. Low aspen recruitment has been attributed to climate patterns, past management, herbivore increases, competitive interactions with conifers, predator and beaver extirpation, and livestock grazing. Several of these potential causes result from direct or indirect actions of human agency. On June 27–28, 2012 a group of leading aspen ecologists from diverse backgrounds convened at the High Lonesome Ranch in western Colorado to address the state …

Investing In Genetics, Bridger Feuz, Dillon M. Feuz

Agriculture Extension professionals as well as other agriculture industry professionals often extol the virtues of being the” low cost producer.” In most cases being the low cost producer does lead to an increase in profitability. However, two different data sets have suggested a couple of areas that high profit producers actually spend more money on then low profit producers.

The Seventh Internationalconference On The Genetics Of Streptococci, Lactococci And Enterococci, R. A. Burne, D. Bessen, Jeff Broadbent, J. P. Claverys

Nutrition, Dietetics, and Food Sciences Faculty Publications

The Seventh International Conference on the Genetics of Streptococci, Lactococci, and Enterococci, sponsored by the American Society for Microbiology, was held 18 to 21 June 2006, overlooking the sea in Saint Malo, Bretagne, France. The conference began in 1981 as the Streptococcal Genetics meeting, at a time when the genera Enterococcus and Lactococcus were still classified as Streptococcus spp. Through the years, this meeting has served as a quadrennial platform to showcase cutting-edge advances in the dissection of the underlying genetics of growth control, metabolism, extrachromosomal elements, substrate utilization, competence development, antibiotic resistance, and virulence of this fascinating group of …

We have not achieved an efficient food production system in US Agriculture by manipulating only the environment.

Genetic engineering techniques now allow us to quickly develop new crop cultivars.

Genetics In Practice A Template For Interactive Case Studies, Erin Edwards, Andrew Walker, Kathleen Bergeson, John Louviere, Kris Robinson, J. W. Higgins

Instructional Technology and Learning Sciences Faculty Publications

Genetics & Your Practice, began in 1994 as a course for primary health care practitioners to get Continuing Medical Education (CME) credits and to help health care providers learn about the importance of genetic counseling and the fundamental difference between genetic counseling and traditional health care. In a collaborative project between the March of Dimes and Idaho State University Departments of Nursing (ISU) and Continuing Education/Special Programs, the course was converted to an online asynchronous course. Since the course was primarily didactic, ISU approached a team of graduate students at Utah State University’s Department of Instructional Technology (USU) to develop …

Ecotypic Differences In Heat Resistance Of Aspen Leaves, K.M. Peck, S.J. Wallner

Aspen Bibliography

Heat resistance of aspen (Populus tremuloides) leaves was assessed by stressing leaf discs in vitro and measuring electrolyte leakage. Leaves were obtained from trees growing at elevations of 1960, 2195, and 2454 m. Heat tolerance was greatest in leaf samples from trees growing at the lowest site. Trees propagated from these sites and grown at 1520 m for 2 years showed some increase in heat tolerance, but apparent ecotypic differences persisted
