2006 Integrated pest management resource guide

Creator:: Jepson, Paul C., Brewer, Linda J., Jepson, Susan B., and Oregon State University. Extension Service
Abstract:: This publication is offered as a reference to Integrated Pest Management (IPM) resources available to Oregon growers. It highlights university, federal, state, and private services and resources that provide support to growers in the implementation of IPM programs. The Guide consists of five sections: • An introduction to the National...

Phytophthora Have Distinct Endogenous Small RNA Populations That Include Short Interfering and microRNAs

Creator:: Fahlgren, Noah, Bollmann, Stephanie R., Kasschau, Kristin D., Cuperus, Josh T., Press, Caroline M., Sullivan, Christopher M., Chapman, Elisabeth J., Hoyer, J. Steen, Gilbert, Kerrigan B., Grunwald, Niklaus J., and Carrington, James C.
Abstract:: In eukaryotes, RNA silencing pathways utilize 20-30-nucleotide small RNAs to regulate gene expression, specify and maintain chromatin structure, and repress viruses and mobile genetic elements. RNA silencing was likely present in the common ancestor of modern eukaryotes, but most research has focused on plant and animal RNA silencing systems. Phytophthora...

High-Throughput Sequencing of Arabidopsis microRNAs : Evidence for Frequent Birth and Death of MIRNA Genes

Creator:: Fahlgren, Noah, Howell, Miya D., Kasschau, Kristin D., Sullivan, Christopher M., Cumbie, Jason S., Givan, Scott A., Law, Theresa F., Grant, Sarah R., Dangl, Jeffrey L., and Carrington, James C.
Abstract:: In plants, microRNAs (miRNAs) comprise one of two classes of small RNAs that function primarily as negative regulators at the posttranscriptional level. Several MIRNA genes in the plant kingdom are ancient, with conservation extending between angiosperms and the mosses, whereas many others are more recently evolved. Here, we use deep...

Potato virus X : detection and inter-relationship with Verticillium dahliae and Colletotrichum atramentarium

Creator:: Goodell, Jody Jellison
Abstract:: Preliminary studies were run to determine the sensitivity and reliability of enzyme-linked immunosorbent assay (ELISA) for the detection of potato virus X (PVX). ELISA was found to be capable of detecting PVX in tobacco at a 1:3333 sample dilution. The reliability of ELISA for the detection of PVX in potato...

Responses and relationships among Fusarium species, sweet corn, and western spotted cucumber beetles

Creator:: Miller, Nathan L. (Nathan Louis)
Abstract:: Sweet corn (Zea mays L.) yields in the Willamette Valley of Oregon have been declining since the early 1990’s. Studies were done to determine if there is a relationship between ear weight and several disease parameters including necrotic crowns or stalk nodes, nodal root rot, radicle root rot, and sub-crown...

Escape in Time: Phenology Mitigates Impacts of the Introduced Cinnabar Moth, Tyria jacobaeae, on Native Herb Senecio triangularis in Western Oregon

Creator:: Lunde, A. Katarina
Abstract:: Classic biological control can be a powerful option for those tasked with managing biological invasions; however, some biocontrol releases lead to non-target attack – feeding, damage or development on species other than the target species. The cinnabar moth, Tyria jacobaeae L. (Lepidoptera: Erebidae) was introduced to Western Oregon as a...

Genomic Resources for Phylogenetics, Species Delimitation, and Geographic Localization of Neotropical Tree Species Cedrela odorata L. (Meliaceae)

Creator:: Finch, Kristen N.
Abstract:: Biodiversity loss is of global concern, and is due in part to deforestation and high consumer demand for wood and wood products. The neotropical tree species Cedrela odorata (“Spanish cedar” or “cedro”) is economically valuable for its wood and faces threats of overexploitation. Due to strong similarities in wood features...

Inferring Patterns and Processes of Emergence in Clonal Phytophthora Epidemics using Population Genomic Approaches

Creator:: Cauldron, Nicholas C.
Abstract:: Oomycete and fungal pathogens threaten food, fiber, and forests around the world. With climate change, these pathogens are expected to emerge more frequently. Evolution can facilitate their emergence through mechanisms such as mutations that change or expand host range. Characterizing evolutionary mechanisms in plant pathogens will contribute to our ability...

Fescue taxonomy in the Pacific coast states

Creator:: Wilson, Barbara L.
Abstract:: Accurate taxonomy is essential to preservation and management of native grasses. Four problems in fescue taxonomy were investigated: the identity of the native fescue that dominates western Oregon and Washington prairies, the relationship of native Festuca roemeri to closely related grasses, the status of F. howellii and F. washingtonica, and...
