The influence of overstory openness on the reproductive
ecology of Pacific yew (Taxus brevifolia Nutt.) was
investigated on 4 sites in western Oregon over 2 years. The
breeding system of T. brevifolia was found to deviate from
pure dioecy under a broad range of canopy and site
conditions. Production of...
The heritability of resistance to eastern filbert blight, caused by Anisogramma anomala, in European hazelnut (Corylus avellana) was evaluated in the progeny of seven cultivars crossed in 12 combinations. Progeny produced by crossing 'VR6-28' with three susceptible cultivars segregated 1:1 for complete resistance to eastern filbert blight. Histograms of disease...
Interactions between proteins and contact surfaces can have
important implications in the food industry. Such interactions
contribute to the course of fouling of membrane surfaces and they
appear to mediate bacterial and spore adhesion to some degree as
well. In addition to protein and solution properties, interfacial
behavior is strongly...

We have developed crown-gall resistant transgenic plants capable of suppressing Agrobacterium tumefaciens T-DNA oncogenes. Crown gall tumors result from overproduction of auxin and cytokinin in plant cells transformed by A. tumefaciens. High phytohormone levels result from expression of two auxin biosynthetic genes, tryptophan monooxygenase (iaaM) and indole acetamide hydrolase (iaaH),...
Instream flow protection in western prior appropriation states is a relatively new phenomenon.
Integrating instream flow protection measures with the older water law has been accomplished with varying
degrees of success. Idaho relies on appropriation of unappropriated water by the Idaho Water Resource Board
for protection of instream flows. Idaho's...
