How Effective Are DNA Barcodes in the Identification of African Rainforest Trees?

Creator:: Parmentier, Ingrid, Duminil, Jérôme, Kuzmina, Maria, Philippe, Morgane, Thomas, Duncan W., Kenfack, David, Chuyong, George B., Cruaud, Corinne, and Hardy, Olivier J.
Abstract:: Background: DNA barcoding of rain forest trees could potentially help biologists identify species and discover new ones. However, DNA barcodes cannot always distinguish between closely related species, and the size and completeness of barcode databases are key parameters for their successful application. We test the ability of rbcL, matK and...

The use of flowering crab apples for the detection of latent viruses in apples

Creator:: Reynolds, James Edward
Abstract:: Recent investigations indicate that several latent viruses of apples exist in common commercial apple stocks, but these viruses and their relationships are incompletely understood. This thesis describes investigations of crab apples as indicators of latent viruses of apples. Eighty-eight varieties and species of crab apples were tested as indicators of...

Fungal endophyte diversity in foliage of native and cultivated Rhododendron species determined by culturing, ITS sequencing, and pyrosequencing

Creator:: Raizen, Nathaniel L.
Abstract:: Western Oregon is home to native Rhododendron species and is the center for cultivated Rhododendron production in the United States. These Rhododendron spp. are known to be infected with fungal endophytes. However, the community structure of these endophytes in native and cultivated Rhododendron is poorly understood. Our study targeted the...

Scratching the Surface of the Potato Geocaulosphere: Characterizing the Microbiome of Seed Tuber Tare Soil and its Impact on the Rhizosphere Microbiome

Creator:: Delventhal, Kayla D.
Abstract:: For tuberizing crops like potato (Solanum tuberosum), the geocaulosphere, or the zone of soil in contact with and influenced by the tuber, is a distinct sphere of microbial life and represents an important interface between the potato crop and the soil environment. Upon potato harvest, specific geocaulosphere soil called tare...

Development of Molecular Markers for Determining Continental Origin of Wood from White Oaks (Quercus L. sect. Quercus)

Creator:: Schroeder, Hilke, Cronn, Richard, Yanbaev, Yulai, Jennings, Tara, Mader, Malte, Degen, Bernd, and Kersten, Birgit
Abstract:: To detect and avoid illegal logging of valuable tree species, identification methods for the origin of timber are necessary. We used next-generation sequencing to identify chloroplast genome regions that differentiate the origin of white oaks from the three continents; Asia, Europe, and North America. By using the chloroplast genome of...

Effect of Tannic Acid on the Transcriptome of the Soil Bacterium Pseudomonas protegens Pf-5

Creator:: Lim, Chee Kent, Penesyan, Anahit, Hassan, Karl A., Loper, Joyce E., and Paulsen, Ian T.
Abstract:: Tannins are a diverse group of plant-produced, polyphenolic compounds with metal-chelating and antimicrobial properties that are prevalent in many soils. Using transcriptomics, we determined that tannic acid, a form of hydrolysable tannin, broadly affects the expression of genes involved in iron and zinc homeostases, sulfur metabolism, biofilm formation, motility, and...

Cytokinin O-glycosyltransferases : biochemical characteristics in vitro and developmental regulation in transgenic plants

Creator:: Veach, Yeonjin Kim
Abstract:: Cytokinins are plant hormones regulating cell division and differentiation. Most developmental events from germination, vegetative morphogenesis to seed and fruit set are influenced by cytokinins. t,ns-Zeatin is the major natural occurring cytokinin. Its isomer, cis-zeatin, and its derivatives are usually present in low quantities and have traditionally been considered as...

Comparative Genomics of a Plant-Pathogenic Fungus, Pyrenophora tritici-repentis, Reveals Transduplication and the Impact of Repeat Elements on Pathogenicity and Population Divergence

Creator:: Manning, Viola A., Pandelova, Iovanna, Dhillon, Braham, Wilhelm, Larry J., Goodwin, Stephen B., Berlin, Aaron M., Figueroa, Melania, Freitag, Michael, Hane, James K., Henrissat, Bernard, Holman, Wade H., Kodira, Chinnappa D., Martin, Joel, Oliver, Richard P., Robbertse, Barbara, Schackwitz, Wendy, Schwartz, David C., Spatafora, Joseph W., Turgeon, B. Gillian, Yandava, Chandri, Young, Sarah, Zhou, Shiguo, Zeng, Qiandong, Grigoriev, Igor V., Ma, Li-Jun, and Ciuffetti, Lynda M.
Abstract:: Pyrenophora tritici-repentis is a necrotrophic fungus causal to the disease tan spot of wheat, whose contribution to crop loss has increased significantly during the last few decades. Pathogenicity by this fungus is attributed to the production of host-selective toxins ( HST), which are recognized by their host in a genotype-specific...

Growth and replacement patterns occuring among selected dominant species associated with plant succession on Douglas fir clear-cuts

Creator:: Robinson, Myles Canby
Abstract:: Growth and replacement patterns of four successionally important species occurring on Douglas fir clear-cuts were investigated from September 1964 to June 1967. The study was carried out on the Marys Peak watershed located near Corvallis, Oregon. Species used in the study include Holcus lanatus, Senecio jacobaea, Lotus crassifolius var. subglaber,...
