Creator:: Ingham, Russell E., Forge, Thomas, and Pinkerton, J. N.
Abstract:: Objectives 1. Survey Oregon vineyards for the presence, identity and abundance of plant-parasitic nematodes. 2. Relate the distribution and abundance of potentially pathogenic species to viticultural practices and site characteristics. 3. Evaluate the efficacy of Nemacur for reducing populations of plant-parasitic nematodes. 4. Document seasonal changes in the abundance of...

Phytophthora ramorum colonizes tanoak xylem and is associated with reduced stem water transport

Creator:: Parke, J. L., Oh, E., Voelker, S., Hansen, E. M., Buckles, G., and Lachenbruch, Barbara
Abstract:: Isolation, detection with diagnostic polymerase chain reaction (PCR), and microscopy demonstrated the presence of Phytophthora ramorum in the sapwood of mature, naturally infected tanoak (Lithocarpus densiflorus) trees. The pathogen was strongly associated with discolored sapwood (P < 0.001), and was recovered or detected from 83% of discolored sapwood tissue samples....

Phytophthora obscura sp nov., a new species of the novel Phytophthora subclade 8d

Creator:: Gruenwald, N. J., Werres, S., Goss, E. M., Taylor, C. R., and Fieland, V. J.
Abstract:: A new Phytophthora species was detected (i) in the USA, infecting foliage of Kalmia latifolia, (ii) in substrate underneath Pieris, and (iii) in Germany in soil samples underneath Aesculus hippocastanum showing disease symptoms. The new species Phytophthora obscura sp. nov. is formally named based on phylogenetic analysis, host range, Kochs...

Kinetic and Spectroscopic Analysis of the Inactivating Effects of Nitric Oxide on the Individual Components of Azotobacter vinelandii Nitrogenase

Creator:: Hyman, Michael R., Seefeldt, Lance C., Morgan, Vance, Arp, Daniel J., and Mortenson, Leonard E.
Abstract:: The effects of nitric oxide (NO) on the individual components of Azotobacter vinelandii nitrogenase have been examined by kinetic and spectroscopic methods. Incubation of the Fe protein (Av2) for 1 h with stoichiometries of 4- and 8-fold molar excesses of NO to Av2 dimer resulted in a complete loss of...

Emerging semantics to link phenotype and environment

Creator:: Thessen, Anne E., Bunkers, Daniel E., Buttigieg, Pier Luigi, Cooper, Laurel D., Dahdul, Wasila M., Domisch, Sami, Franz, Nico M., Jaiswal, Pankaj, Lawrence-Dill, Carolyn J., Midford, Peter E., Mungall, Christopher J., Ramírez, Martín J., Specht, Chelsea D., Vogt, Lars, Aldo Vos, Rutger, Walls, Ramona L., White, Jeffrey W., Zhang, Guanyang, Deans, Andrew R., Huala, Eva, Lewis, Suzanna E., and Mabee, Paula M.
Abstract:: Understanding the interplay between environmental conditions and phenotypes is a fundamental goal of biology. Unfortunately, data that include observations on phenotype and environment are highly heterogeneous and thus difficult to find and integrate. One approach that is likely to improve the status quo involves the use of ontologies to standardize...

An Ephemeral Sexual Population of Phytophthora infestans in the Northeastern United States and Canada

Creator:: Danies, Giovanna, Myers, Kevin, Mideros, María F., Restrepo, Silvia, Martin, Frank N., Cooke, David E. L., Smart, Christine D., Ristaino, Jean B., Seaman, Abby J., Gugino, Beth K., Grünwald, Niklaus J., and Fry, William E.
Abstract:: Phytophthora infestans, the causal agent of late blight disease, has been reported in North America since the mid-nineteenth century. In the United States the lack of or very limited sexual reproduction has resulted in largely clonal populations of P. infestans. In 2010 and 2011, but not in 2012 or 2013,...

Developing Models for the Forage Ratios of Culiseta melanura and Culex erraticus using Species Characteristics for Avian Hosts

Creator:: Estep, Laura K., McClure, Christopher J. W., Burkett-Cadena, Nathan D., Hassan, Hassan K., Unnasch, Thomas R., and Hill, Geoffrey E.
Abstract:: Studies of mosquito preferences for avian hosts have found that some bird species are at greater risk than others of being fed upon by mosquitoes. The ecological factors that determine this interspecific variation in avian host use by mosquitoes have been little studied, despite the possibility that such variation may...

Regional to global assessments of phytoplankton dynamics from the SeaWiFS mission

G., and Yoder, J. A.
Abstract:: Photosynthetic production of organic matter by microscopic oceanic phytoplankton fuels ocean ecosystems and contributes roughly half of the Earth's net primary production. For 13 years, the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) mission provided the first consistent, synoptic observations of global ocean ecosystems. Changes in the surface chlorophyll concentration, the primary...

Abstract:: The ascomycete fungus Tolypocladium inflatum, a pathogen of beetle larvae, is best known as the producer of the immunosuppressant drug cyclosporin. The draft genome of T. inflatum strain NRRL 8044 (ATCC 34921), the isolate from which cyclosporin was first isolated, is presented along with comparative analyses of the biosynthesis of...
