Seed germination sensu stricto is defined as the physiological events before the radicle tip ruptures the covering tissues. The ability of the radicle to elongate (or germination potential) is observed in developing embryos prior to completion of seed maturation. When embryos at early developmental stages, such as globular, heart, torpedo...
Root rot of sweet corn in western Oregon and Washington is a significant disease that
can reduce yield of intolerant cultivars of processed sweet corn by fifty percent. Root rot
is caused by a complex of soilborne organisms, including Drechslera sp., Phoma
terrestris, and Pythium arrhenomanes. Processors have adopted tolerant...
The hundred-year history of the hazelnut industry in the Pacific Northwest is threatened by eastern filbert blight (EFB) caused by the fungus Anisogramma anomala (Peck) E. Müller. Marker-assisted selection (MAS) has been extensively used for ‘Gasaway’ resistance in the hazelnut breeding program at Oregon State University. Concern over breakdown of...
Oregon Biography Index is intended to serve primarily as a starting point in locating biographies of Oregonians. We have indexed 47 historical volumes which are either entirely devoted to biographies or have large self-contained biographical sections. The profiles in the books vary widely in accuracy and detail. Birth dates of...
The purpose of this research was to compare four different media that were used to monitor SOC atmospheric concentrations in remote ecosystems. The accumulation of semi-volatile organic compounds, including pesticides, polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), was investigated in lichen, 2-year old conifer needles, resin-based passive air sampling...
Plants develop a vast array of cell shapes and sizes by selectively modifying their surrounding cell walls to expand in some regions and not in others. This process of morphogenesis requires the delivery of secretory vesicles to specific locations at the cell periphery, where exocytosis adds new membrane and proteins...
Women living in sub-Saharan Africa are more affected by HIV/AIDS than any other population in the world. Two-thirds of all new HIV infections worldwide occur in sub-Saharan Africa and over 60% of these infections are in women. Indeed, 70% of
all women globally who are infected with HIV reside in...
