Catalyst selective and regiodivergent O- to C- or N-carboxyl transfer of pyrazolyl carbonates: synthetic and computational studies

Creator:: Gould, Eoin, Walden, Daniel M., Kasten, Kevin, Johnston, Ryne C., Wu, Jiufeng, Slawin, Alexandra M., Mustard, Thomas J. L., Johnston, Brittany, Davies, Tony, Cheong, Paul Ha-Yeon, and Smith, Andrew D.
Abstract:: The regiodivergent O- to C- or N-carboxyl transfer of pyrazolyl carbonates is described, with DMAP giving preferential N-carboxylation and triazolinylidenes promoting selective C-carboxylation (both with up to >99 : 1 regioselectivity). An enantioselective O- to C-carboxyl variant using NHC catalysis is demonstrated (up to 92% ee), while mechanistic and DFT studies outline...

High-Density SNP Genotyping of Tomato (Solanum lycopersicum L.) Reveals Patterns of Genetic Variation Due to Breeding

Creator:: Sim, Sung-Chur, Van Deynze, Allen, Stoffel, Kevin, Douches, David S., Zarka, Daniel, Ganal, Martin W., Chetelat, Roger T., Hutton, Samuel F., Scott, John W., Gardner, Randolph G., Panthee, Dilip R., Mutschler, Martha, Myers, James R., and Francis, David M.
Abstract:: The effects of selection on genome variation were investigated and visualized in tomato using a high-density single nucleotide polymorphism (SNP) array. 7,720 SNPs were genotyped on a collection of 426 tomato accessions (410 inbreds and 16 hybrids) and over 97% of the markers were polymorphic in the entire collection. Principal...

Mutualistic Co-evolution of Type III Effector Genes in Sinorhizobium fredii and Bradyrhizobium japonicum

Creator:: Kimbrel, Jeffrey A., Thomas, William J., Jiang, Yuan, Creason, Allison L., Thireault, Caitlin A., Sachs, Joel L., and Chang, Jeff H.
Abstract:: Two diametric paradigms have been proposed to model the molecular co-evolution of microbial mutualists and their eukaryotic hosts. In one, mutualist and host exhibit an antagonistic arms race and each partner evolves rapidly to maximize their own fitness from the interaction at potential expense of the other. In the opposing...

Regional variation in stand structure and development in forests of Oregon, Washington, and inland Northern California

Creator:: Reilly, Matthew J. and Spies, Thomas A.
Abstract:: Despite its importance to biodiversity and ecosystem function, patterns and drivers of regional scale variation in forest structure and development are poorly understood. We characterize structural variation, create a hierarchical classification of forest structure, and develop an empirically based framework for conceptualizing structural development from 11,091 plots across 25 million...

Post-fire tree establishment and early cohort development in conifer forests of the western Cascades of Oregon, USA

Creator:: Tepley, Alan J., Swanson, Frederick J., and Spies, Thomas A.
Abstract:: Early‐seral ecosystems make important contributions to regional biodiversity by supporting high abundance and diversity of many plant and animal species that are otherwise rare or absent from closed‐canopy forests. Therefore, the period of post‐fire tree establishment is a key stage in forest stand and ecosystem development that can be viewed...

Evaluating Paratransgenesis as a Potential Control Strategy for African Trypanosomiasis

Creator:: Medlock, Jan, Atkins, Katherine E., Thomas, David N., Aksoy, Serap, and Galvani, Alison P.
Abstract:: Genetic-modification strategies are currently being developed to reduce the transmission of vector-borne diseases, including African trypanosomiasis. For tsetse, the vector of African trypanosomiasis, a paratransgenic strategy is being considered: this approach involves modification of the commensal symbiotic bacteria Sodalis to express trypanosome-resistance-conferring products. Modified Sodalis can then be driven into...

Differential surface activation of the A1 domain of von Willebrand factor

Creator:: Tronic, Elaine H., Yakovenko, Olga, Weidner, Tobias, Baio, Joe E., Penkala, Rebecca, Castner, David G., and Thomas, Wendy E.
Abstract:: The clotting protein von Willebrand factor (VWF) binds to platelet receptor glycoprotein Ibα (GPIbα) when VWF is activated by chemicals, high shear stress, or immobilization onto surfaces. Activation of VWF by surface immobilization is an important problem in the failure of cardiovascular implants, but is poorly understood. Here, the authors...

Evolutionary Biology for the 21st Century

Creator:: Losos, Jonathan B., Arnold, Stevan J., Bejerano, Gill, Brodie, E. D. III, Hibbett, David, Hoekstra, Hopi E., Mindell, David P., Monteiro, Antonia, Moritz, Craig, Orr, H. Allen, Petrov, Dmitri A., Renner, Susanne S., Ricklefs, Robert E., Soltis, Pamela S., and Turner, Thomas L.
Abstract:: We live in an exciting time for biology. Technological advances have made data collection easier and cheaper than we could ever have imagined just 10 years ago. We can now synthesize and analyze large data sets containing genomes, transcriptomes, proteomes, and multivariate phenotypes. At the same time, society's need for...

Predicting foundation bunchgrass species abundances: model-assisted decision-making in protected-area sagebrush steppe

Creator:: Rodhouse, Thomas J., Irvine, Kathryn M., Sheley, Roger L., Smith, Brenda S., Hoh, Shirley, Esposito, Daniel M., and Mata-Gonzalez, Ricardo
Abstract:: Foundation species are structurally dominant members of ecological communities that can stabilize ecological processes and influence resilience to disturbance and resistance to invasion. Being common, they are often overlooked for conservation but are increasingly threatened from land use change, biological invasions, and over‐exploitation. The pattern of foundation species abundances over...

A bioenergetics model to evaluate demographic consequences of disturbance in marine mammals applied to gray whales

Creator:: Villegas-Amtmann, S., Schwarz, L. K., Sumich, J. L., and Costa, D. P.
Abstract:: While sophisticated tools are used to monitor behavioral changes of large marine vertebrates, determining whether these changes are meaningful for management and conservation is challenging. The Population Consequences of Disturbance model proposed a bioenergetics model to detect biologically meaningful population responses, where disturbance costs are linked to lost energy. The...
