Thauera butanivorans sp. nov., a C₂–C₉ alkane-oxidizing bacterium previously referred to as ‘Pseudomonas butanovora’

Creator:: Dubbels, Bradley L., Sayavedra-Soto, Luis A., Bottomley, Peter J., and Arp, Daniel J.
Abstract:: The placement of ‘Pseudomonas butanovora’ in the genus Thauera was proposed previously, based on 16S rRNA gene sequence analysis, upon further studies of taxonomical characteristics. In this study, physiological characteristics and DNA–DNA reassociation data are presented and the transfer of ‘P. butanovora’ to the genus Thauera is proposed. The original...

Distinct Argonaute-mediated 22G-RNA pathways direct genome surveillance in the C. elegans germline

Creator:: Gu, Weifeng, Shirayama, Masaki, Conte Jr., Darryl, Vasale, Jessica, Batista, Pedro J., Claycomb, Julie M., Moresco, James J., Youngman, Elaine, Keys, Jennifer, Stoltz, Matthew J., Chen, Chun-Cheih G., Chaves, Daniel A., Duan, Shenghua E., Kasschau, Krisitin D., Fahlgren, Noah, Yates III, John R., Mitani, Shohei, Carrington, James C., and Mello, Craig C.
Abstract:: Endogenous small RNAs (endo-siRNAs) interact with Argonaute (AGO) proteins to mediate sequence-specific regulation of diverse biological processes. Here, we combine deep-sequencing and genetic approaches to explore the biogenesis and function of endo-siRNAs in C. elegans. We describe conditional alleles of the dicer-related helicase, drh-3, that abrogate both RNA interference and...

Population Density and Phenology of Tetranychus urticae (Acari: Tetranychidae) in Hop is Linked to the Timing of Sulfur Applications

Creator:: Woods, J. L., Dreves, A. J., Fisher, Glenn C., James, David G., Wright, Larry C., and Gent, D. H.
Abstract:: The twospotted spider mite, Tetranychus urticae Koch, is a worldwide pest of numerous agronomic and horticultural plants. Sulfur fungicides are known to induce outbreaks of this pest on several crops, although mechanisms associated with sulfur-induced mite outbreaks are largely unknown. Studies were conducted during 2007–2009 in Oregon and Washington hop...

Identification of quantitative trait loci (QTL) for resistance to Fusarium crown rot (Fusarium pseudograminearum) in multiple assay environments in the Pacific Northwestern US

Creator:: Poole, G. J., Smiley, R. W., Paulitz, T. C., Walker, C. A., Carter, A. H., and See, D. R.
Abstract:: Fusarium crown rot (FCR), caused by and , reduces wheat ( L.) yields in the Pacific Northwest (PNW) of the US by as much as 35%. Resistance to FCR has not yet been discovered in currently grown PNW wheat cultivars. Several significant quantitative trait loci (QTL) for FCR resistance have...

Vitamin B1 content in potato: effect of genotype, tuber enlargement, and storage, and estimation of stability and broad-sense heritability

Creator:: Goyer, Aymeric and Haynes, Kathleen G.
Abstract:: Thiamine pyrophosphate (vitamin B1) is an essential nutrient in the human diet, and is often referred as the energy vitamin. Potato contains modest amounts of thiamine. However, the genetic variation of thiamine concentrations in potato has never been investigated. In this study, we determined thiamine concentrations in freshly-harvested unpeeled tubers...

Virus-Derived Gene Expression and RNA Interference Vector for Grapevine

Creator:: Kurth, Elizabeth G., Peremyslov, Valera V., Prokhnevsky, Alexey I., Kasschau, Kristin D., Miller, Marilyn, Carrington, James C., and Dolja, Valerian V.
Abstract:: The improvement of the agricultural and wine-making qualities of the grapevine (Vitis vinifera) is hampered by adherence to traditional varieties, the recalcitrance of this plant to genetic modifications, and public resistance to genetically modified organism (GMO) technologies. To address these challenges, we developed an RNA virus-based vector for the introduction...

Evidence that the Potyvirus P1 Proteinase Functions in trans as an Accessory Factor for Genome Amplification

Creator:: Verchot, Jeanmarie and Carrington, James C.
Abstract:: The tobacco etch potyvirus (TEV) polyprotein is proteolytically processed by three viral proteinases (NIa, HC-Pro, and P1). While the NIa and HC-Pro proteinases each provide multiple functions essential for viral infectivity, the role of the P1 proteinase beyond its autoproteolytic activity is understood poorly. To determine if P1 is necessary...

Senftenbergia oregonensis (Arnold) comb. nov. (Filicales): Delimiting Relationships Among Paleozoic Tedeleaceae

Creator:: Hillier, Kaitlin G. and Rothwell, Gar W.
Abstract:: Reexamination of fossilized plant material from the westernmost Pennsylvanian-age wetland flora in North America reveals that material of Pecopteris oregonensis Arnold represents a filicalean fern frond with annulate sporangia and anatomically preserved vascular tissues of the rachis. The frond, which is redescribed as Senftenbergia oregonensis (Arnold) Hillier et Rothwell comb....

Debilitation of Plant Potyvirus Infectivity by P1 Proteinase-Inactivating Mutations and Restoration by Second-Site Modifications

Creator:: Verchot, Jeanmarie and Carrington, James C.
Abstract:: Tobacco etch virus (TEV) encodes three proteinases that catalyze processing of the genome-encoded polyprotein. The P1 proteinase originates from the N terminus of the polyprotein and catalyzes proteolysis between itself and the helper component proteinase (HC-Pro). Mutations resulting in substitution of a single amino acid, small insertions, or deletions were...

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...
