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...

Regional to global assessments of phytoplankton dynamics from the SeaWiFS mission

Creator:: Siegel, D. A., Behrenfeld, Michael J., Maritorena, S., McClain, C. R., Antoine, D., Bailey, S. W., Bontempi, P. S., Boss, E. S., Dierssen, H. M., Doney, S. C., Eplee, R. E. Jr., Evans, R. H., Feldman, G. C., Fields, E., Franz, B. A., Kuring, N. A., Mengelt, C., Nelson, N. B., Patt, F. S., Robinson, W. D., Sarmiento, J. L., Swan, C. M., Werdell, P. J., Westberry, T. K., Wilding, J. 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...

Annual cycles of ecological disturbance and recovery underlying the subarctic Atlantic spring plankton bloom

Creator:: Behrenfeld, Michael J., Doney, Scott C., Lima, Ivan, Boss, Emmanuel S., and Siegel, David A.
Abstract:: Satellite measurements allow global assessments of phytoplankton concentrations and, from observed temporal changes in biomass, direct access to net biomass accumulation rates (r). For the subarctic Atlantic basin, analysis of annual cycles in r reveals that initiation of the annual blooming phase does not occur in spring after stratification surpasses...

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....

SNP-Based Differentiation of Phytophthora infestans Clonal Lineages Using Locked Nucleic Acid Probes and High-Resolution Melt Analysis

Creator:: Hansen, Zachariah R., Knaus, Brian J., Tabima, Javier F., Press, Caroline M., Judelson, Howard S., Grünwald, Niklaus J., and Smart, Christine D.
Abstract:: Phytophthora infestans, the cause of the devastating late blight disease of potato and tomato, exhibits a clonal reproductive lifestyle in North America. Phenotypes such as fungicide sensitivity and host preference are conserved among individuals within clonal lineages, while substantial phenotypic differences can exist between lineages. Whole P. infestans genomes were...

Sclerotinia Wilt of Hop (Humulus lupulus) Caused by Sclerotinia sclerotiorum in the Pacific Northwest United States

Creator:: Kropf, S. M., Putnam, M. L., Serdani, M., Twomey, M. C., Woods, J. L., and Gent, D. H.
Abstract:: In June 2009, wilted hop bines were observed in a yard in Marion County, OR. The wilt was associated with a stem rot that occurred ∽1 m from the ground near the point where bines are tied together for horticultural purposes. Samples of affected stems were submitted to the Oregon...

Genome-Wide Profiling and Analysis of Arabidopsis siRNAs

Creator:: Kasschau, Kristin D., Fahlgren, Noah, Chapman, Elisabeth J., Sullivan, Christopher M., Cumbie, Jason S., Givan, Scott A., and Carrington, James C.
Abstract:: Eukaryotes contain a diversified set of small RNA-guided pathways that control genes, repeated sequences, and viruses at the transcriptional and posttranscriptional levels. Genome-wide profiles and analyses of small RNAs, particularly the large class of 24-nucleotide (nt) short interfering RNAs (siRNAs), were done for wild-type Arabidopsis thaliana and silencing pathway mutants...

The Genome of Tolypocladium inflatum: Evolution, Organization, and Expression of the Cyclosporin Biosynthetic Gene Cluster

Creator:: Bushley, Kathryn E., Raja, Rajani, Jaiswal, Pankaj, Cumbie, Jason S., Nonogaki, Mariko, Boyd, Alexander E., Owensby, C. Alisha, Knaus, Brian J., Elser, Justin, Miller, Daniel, Di, Yanming, McPhail, Kerry L., and Spatafora, Joseph W.
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...

Computational and analytical framework for small RNA profiling by high-throughput sequencing

Creator:: Fahlgren, Noah, Sullivan, Christopher M., Kasschau, Krisitin D., Chapman, Elisabeth J., Cumbie, Jason S., Montgomery, Taiowa A., Gilbert, Sunny D., Dasenko, Mark, Backman, Tyler W. H., Givan, Scott A., and Carrington, James C.
Abstract:: The advent of high-throughput sequencing (HTS) methods has enabled direct approaches to quantitatively profile small RNA populations. However, these methods have been limited by several factors, including representational artifacts and lack of established statistical methods of analysis. Furthermore, massive HTS data sets present new problems related to data processing and...
