(1970-04-24)A two phase investigation was undertaken in an attempt to determine the effects of variations in salinity on the distribution of benthic estuarine diatoms. The estuary studied was that of the Yaquina River which originat ...
-
(2011-09-07)The semi-arid sagebrush steppe ecosystem is one of the largest biomes in North America. The steppe provides critical habitat and forage for wildlife and is economically important to recreation and livestock industries. ...
-
(Botanical Society of America, 2012-04)Premise of the study: Pinaceae and nonpinoid species are sister groups within the conifer clade as inferred from molecular systematic comparisons of living species and therefore should have comparable geological ages. Ho ...
-
(2002-03-11)Seed piece to plant transmission of the potato late blight pathogen, Phytophthora infestans, occurred with isolates of the clonal lineages US-8 in Oregon and US-11 in Washington in field trials. Average transmission ra ...
-
(The University of Chicago Press, 2012-06)Reexamination of fossilized plant material from the westernmost Pennsylvanian-age wetland flora in North America reveals that material of Pecopteris oregonensis Arnold represents a filicalean fern frond with annulate spo ...
-
(American Phytopathological Society, 2012-05)Many plant disease epidemic models, and the disease management decision aids developed from them, are created based on temperature or other weather conditions measured in or above the crop canopy at intervals of 15 or 30 ...
-
(2000-09-19)Cephalosporium stripe, caused by the soil-borne ascomycete Cephalosporium gramineum, is becoming an increasingly important disease of winter wheat (Triticum aestivum) in several areas of the world, especially where stu ...
-
(BioMed Central Ltd., 2012-06-25)Background: Through next-generation sequencing, the amount of sequence data potentially available for phylogenetic analyses has increased exponentially in recent years. Simultaneously, the risk of incorporating ‘noisy’ d ...
-
(1999-07-08)Raspberry bushy dwarf virus (RBDV) is the sole member of the idaeovirus genus of plant viruses. It is a pollen-borne virus that economically impacts both red and black raspberries worldwide. Three strains of the bipart ...
-
(Oxford University Press, 2012-10-04)Gene synthesis attempts to assemble user-defined DNA sequences with base-level precision. Verifying the sequences of construction intermediates and the final product of a gene synthesis project is a critical part of the ...
-
(1995-06-30)Polyclonal antisera were raised against isolates of bean common mosaic virus (BCMV) and bean common mosaic necrosis virus (BCMNV) using conventional serological methods. Infected tissues containing, respectively, 22 r ...
-
(2000-04-07)This dissertation describes the epiphyte communities on tall shrubs in forests of western Oregon, with a focus on potential effects of management practices on these communities. Shrubs and other hardwoods have recently ...
-
(European Molecular Biology Organization, 2006)RNA silencing is an evolutionarily conserved system that functions as an antiviral mechanism in higher plants and insects. To counteract RNA silencing, viruses express silencing suppressors that interfere with both si ...
-
(National Academy of Science, 2009-10-20)Small RNAs, including microRNAs (miRNAs), small interfering RNAs (siRNAs), and trans-acting siRNAs (tasiRNAs), control gene expression and epigenetic regulation. Although the roles of miRNAs and siRNAs have been exten ...
-
(1993-02-26)A greenhouse experiment was conducted in 1991 and in 1992 to determine the effect of soil water pressure on potato (cv Russet Burbank) plant growth and infection by Verticillium dahliae. Soil water pressures of -0.01, ...
-
(1968-07-31)Black Butte presents a unique natural laboratory for ecological study. It is a volcanic cone of uniform configuration located in the rain shadow on the east flank of the Oregon Cascades. Soils are of very recent origi ...
-
(2009-02-17)We list additions, deletions, and other changes in species included in Macrolichens of the Pacific Northwest, 2nd edition, as compared to the 1st edition. The changes resulted from discoveries of range extensions into th ...
