A common garden study investigated growth, morphology, and cold hardiness of yellow-cedar (Chamaecyparis nootkatensis (D. Don) Spach) seedlings originating from seed that had matured at an accelerated rate. This early maturing seed, produced at a low-elevation southern Vancouver Island seed orchard, was known to have similar germinability and seedling morphology...
Previous laboratory and field studies have presented evidence for the existence of limestone ecotypes in white spruce (Picea glauca (Moench) Voss). Remeasurements of the range-wide 410 series of provenance trials were used for further evaluation of the existence of these ecotypes. In 2001, heights were measured of 23 provenances grown...
Intraspecific assisted migration (ISAM) through seed transfer during artificial forest regeneration has been suggested as an adaptation strategy to enhance forest resilience and productivity under future climate. In this study, we assessed the risks and benefits of ISAM in white spruce based on long-term and multilocation, rangewide provenance test data....
The vascular system transports components essential to the survival of the individual and acts as a barrier to substances that may injure the organism. Atherosclerosis is a dynamic, lesion producing disease of the arterial system that compromises the functioning of the organ by occlusive and thrombogenic processes. This investigation was...
Grafted grapevines will become increasingly important in Oregon vineyards in order to prevent loss of plants to phylloxera infestations. Several rootstocks are now being evaluated in Oregon for horticultural traits and characteristics related to wine quality. Resistance or tolerance to other plant diseases affecting grapevines needs to be examined as...
Oregon is a leader in production of premium wines in the United States and the industry has been expanding rapidly over the past few years. However, continued production and expansion of vineyards are threatened by infestation of phylloxera, Daktulospaira vitifoliae, an insect that feeds on roots. Most grapevines in Oregon...

Gold nanoparticles (AuNPs) are increasingly used in biomedical applications,
hence understanding the processes that affect their biocompatibility and stability are of
significant interest. In this study, we assessed the stability of peptide-capped AuNPs and
used the embryonic zebrafish (Danio rerio) as a vertebrate system to investigate the impact
of synthesis...

Crown gall can develop on grapevines wounded by freezing temperatures, mechanical damage or grafting. Increased demand for grape varieties grafted to phylloxera resistant rootstocks has led to increased incidence of crown gall at graft unions. Therefore a search for plant material that is resistant to crown gall has been undertaken....
Crown gall can develop on grapevines wounded by freezing temperatures, mechanical damage or grafting. Pathogenic agrobacteria residing within the vascular system are able to initiate tumor growth in damaged plant cells. Sampling from 21 sites in Oregon vineyards and nurseries yielded diverse populations of pathogenic agrobacteria. Most of the pathogenic...

Agrobacterium vitis is a bacterium that causes crown gall in grapevines. Plant injury from freezing temperatures or mechanical damage during cultivation often provide wounds required for infection to occur. Crown gall may kill grapevines and a new shoot is often brought up from the root to replace dead vines. Discovery...
Development of herbicide-resistant crops has resulted in significant changes to agronomic practices, one of which is the adoption of effective, simple, low-risk, crop-production systems with less dependency on tillage and lower energy requirements. Overall, the changes have had a positive environmental effect by reducing soil erosion, the fuel use for...
Despite the challenges, in-home help may be the best option even for a short time. However, deciding what help you need and selecting a worker is a sizable task that requires careful thought, planning, and research. This publication is a guide through
the maze of finding, screening, and hiring an...
This publication is designed to give family and professional caregivers a fuller understanding of dementia in later life and ways to cope more effectively with the changes resulting from it.
In addition to general care guidelines, the publication outlines approaches for handling specific problems —driving, wandering, money management, hiding items,...
Differentiating salient histopathologic changes from normal anatomic features or tissue artifacts can be decidedly challenging, especially for the novice fish pathologist. As a consequence, findings of questionable accuracy may be reported inadvertently, and the potential negative impacts of publishing inaccurate histopathologic interpretations are not always fully appreciated. The objectives of...
The Gene Ontology (GO) Consortium (http://www.geneontology.org) (GOC) continues to develop,
maintain and use a set of structured, controlled
vocabularies for the annotation of genes, gene
products and sequences. The GO ontologies
are expanding both in content and in structure.
Several new relationship types have been introduced
and used, along with...
