Creator:: Moore, Larry W. and Canfield, Marilyn
Abstract:: The objectives of this study are to isolate and characterize pathogenic agrobacteria that cause crown gall in grapevines and test hot water dips as a method for eradicating the infectious bacteria . Crown gall is commonly found among Oregon vineyards and the causative agent, Agrobacterium vitis, is known to be...

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...

Phylogeny and Biogeography of Primula sect. Parryi (Primulaceae)

Creator:: Kelso, Sylvia, Beardsley, Paul M., and Weitemier, Kevin
Abstract:: Primula sect. Parryi comprises five species endemic to western North America: P. parryi, P. angustifolia, P. rusbyi, P. capillaris, and P. cusickiana with four varieties. This section, derived from a clade with representatives in Asia and Europe, exemplifies a phytogeographic pattern in which a widespread species is accompanied by multiple...

Latent homology and convergent regulatory evolution underlies the repeated emergence of yeasts

Creator:: Nagy, László G., Ohm, Robin A., Kovács, Gábor M., Floudas, Dimitrios, Riley, Robert, Gácser, Attila, Sipiczki, Mátyás, Davis, John M., Doty, Sharon L., de Hoog, G Sybren, Lang, B. Franz, Spatafora, Joseph W., Martin, Francis M., Grigoriev, Igor V., and Hibbett, David S.
Abstract:: Convergent evolution is common throughout the tree of life, but the molecular mechanisms causing similar phenotypes to appear repeatedly are obscure. Yeasts have arisen in multiple fungal clades, but the genetic causes and consequences of their evolutionary origins are unknown. Here we show that the potential to develop yeast forms...

Whole-Plant Growth Stage Ontology for Angiosperms and Its Application in Plant Biology

Creator:: Pujar, Anuradha, Jaiswal, Pankaj, Kellogg, Elizabeth A., Ilic, Katica, Vincent, Leszek, Avraham, Shulamit, Stevens, Peter, Zapata, Felipe, Reiser, Leonore, Rhee, Seung Y., Sachs, Martin M., Schaeffer, Mary, Stein, Lincoln, Ware, Doreen, and McCouch, Susan
Abstract:: Plant growth stages are identified as distinct morphological landmarks in a continuous developmental process. The terms describing these developmental stages record the morphological appearance of the plant at a specific point in its life cycle. The widely differing morphology of plant species consequently gave rise to heterogeneous vocabularies describing growth...

Taking the Next Step: Building an Arabidopsis Information Portal

Creator:: International Arabidopsis Informatics Consortium, Bastow, Ruth, Beynon, Jim, Brendel, Volker, Dooley, Rion, Friesner, Joanna, Grotewold, Erich, Huala, Eva, Loraine, Ann, Meyers, Blake, Pires, J. Chris, Provart, Nicholas, Stanzione, Dan, Town, Chris, and Ware, Doreen
Abstract:: The Arabidopsis Information Portal (AIP), a resource expected to provide access to all community data and combine outputs into a single user-friendly interface, has emerged from community discussions over the last 23 months. These discussions began during two closely linked workshops in early 2010 that established the International Arabidopsis Informatics...

The Plant Structure Ontology, a Unified Vocabulary of Anatomy and Morphology of a Flowering Plant

Creator:: Ilic, Katica, Kellogg, Elizabeth A., Jaiswal, Pankaj, Zapata, Felipe, Stevens, Peter F., Vincent, Leszek P., Avraham, Shulamit, Reiser, Leonore, Pujar, Anuradha, Sachs, Martin M., Whitman, Noah T., McCouch, Susan R., Schaeffer, Mary L., Ware, Doreen H., Stein, Lincoln D., and Rhee, Seung Y.
Abstract:: Formal description of plant phenotypes and standardized annotation of gene expression and protein localization data require uniform terminology that accurately describes plant anatomy and morphology. This facilitates cross species comparative studies and quantitative comparison of phenotypes and expression patterns. A major drawback is variable terminology that is used to describe...

Gramene: a bird's eye view of cereal genomes

Creator:: Jaiswal, Pankaj, Ni, Junjian, Yap, Immanuel, Ware, Doreen, Spooner, William, Youens-Clark, Ken, Canaran, Payan, Fogleman, Molly, Hebbard, Claire, Ren, Liya, Liang, Chengzhi, Zhao, Wei, Ratnapu, Kiran, Faga, Benjamin, Avraham, Shuly, Schmidt, Steven, Casstevens, Terry M., Buckler, Edward S., Stein, Lincoln, and McCouch, Susan
Abstract:: Rice, maize, sorghum, wheat, barley and the other major crop grasses from the family Poaceae (Gramineae) are mankind’s most important source of calories and contribute tens of billions of dollars annually to the world economy (FAO 1999, http://www.fao.org; USDA 1997, http://www.usda.gov). Continued improvement of Poaceae crops is necessary in order...

Expression, Splicing, and Evolution of the Myosin Gene Family in Plants

Creator:: Peremyslov, Valera V., Mockler, Todd C., Filichkin, Sergei A., Fox, Samuel E., Jaiswal, Pankaj, Makarova, Kira S., Koonin, Eugene V., and Dolja, Valerian V.
Abstract:: Plants possess two myosin classes, VIII and XI. The myosins XI are implicated in organelle transport, filamentous actin organization, and cell and plant growth. Due to the large size of myosin gene families, knowledge of these molecular motors remains patchy. Using deep transcriptome sequencing and bioinformatics, we systematically investigated myosin...

Fungitoxicity of silver salts

Creator:: Guilford, Roger Kirby
Abstract:: The demand for new fungicides to control plant diseases has led to experimentation with both previously used and newly developed fungicides. Silver, an older but little used fungicide, was selected for evaluation because of its high toxicity to microorganisms. Silver nitrate and a silver electrolytic cell were tested as potential...

An analysis of montane forest vegetation on the east flank of the central Oregon Cascades

Creator:: West, Neil E.
Abstract:: Montane forest vegetation as it occurs on the east flank of the central Oregon Cascades has provided excellent conditions for a "natural experiment" in the use of various methodologies in studying vegetational distribution. This "experiment" has reflected on some theory and practice for the discipline of plant synecology. Detailed descriptions,...

Comparative anatomical study of three species of Microseris

Creator:: Soedjono, Estiti Harti
Abstract:: Three growth forms of the genus Microseris, of the tribe Cichorieae, family Compositae, were compared with respect to their anatomical structure. The purpose of this study was to clarify lines of evolutionary specialization in the genus. Two of the three species studied, M. laciniata and M. borealis, are perennials, while...
