A stratigraphic study of the marine Cretaceous rocks near Mitchell, Oregon

Creator:: McKnight, Brian Keith
Abstract:: Nearly 9,000 feet of Cretaceous mudstones, shales, sandstone, and conglomerates are exposed along the northeast-trending Mitchell anticline of central Oregon, These rocks are divided into two formations on the basis of criteria developed in this investigation. The lower formation, hereby designated the Meyers Formation, is 4,716 feet thick at its...

Quantitative trait loci influencing free-threshing habit and spike morphology in wheat (Triticum aestivum L.)

Creator:: Jantasuriyarat, Chatchawan
Abstract:: Spike morphology characteristics and the free-threshing habit of wheat have been extensively investigated because of their evolutionary significance and practical importance. Several genetic systems that govern these traits have been reported. Some studies suggest polygenic inheritance while others have identified major genes. This study was conducted to identify and locate...

Triticum enhancer of zeste 1 (Tezl), a homolog of enhancer of zeste in Triticum monococcum

Creator:: Nunes, Jason L.
Abstract:: The Polycomb group (PcG) of genes of Drosophila melanogaster Meigen are involved in developmental regulation through chromatin remodeling. Homologs of PcG genes have been identified in both plant and animal species. In this study, we detail the identification and characterization of Triticum enhancer of zeste 1 (Tez1), a homolog of...

Localization and genetic mapping of some factors influencing rachis brittleness and free-threshing habit in wheat

Creator:: Nalam, Vamsi J.
Abstract:: Domesticated forms of wheat exhibit traits that have increased their adaptation to cultivation by humans. Some of the most critical adaptive differences involve changes to morphological features that make the crop easier to harvest like ear rachis stiffness (brittle to non-brittle rachis) and the ease with which the seed is...

Spatiotemporal distribution of the anti-diabetic drug, metformin, in the lower Columbia River and its effect on phytoplankton growth

Creator:: Cummings, Brittany M.
Abstract:: Water quality impacts both human and ecosystem health. Many pharmaceuticals and personal care products are considered contaminants of emerging concern (CEC) due to their bioactive properties. Among these, metformin—the most commonly prescribed drug for treatment of type 2 diabetes—has been reported at high concentrations (μg L⁻¹) in stream, lake, and...

The mesoscale wind field during project JASIN 1972

Creator:: Cummings, Timothy K.
Abstract:: The wind field measured during Project JASIN 1972, a joint British-American venture during September 1972, was analyzed. These measurements were done, with equipment manufactured by Ivar Aanderaa of Bergen, Norway, on large, anchored toroid buoys. The results of the analysis of the wind field, which included divergence and vorticity estimates...

Exiles and rebels : women in the American left 1900-1920

Creator:: Cummings, Katherine H.
Abstract:: Between 1900 and 1920 women were responsible for much of the social and political activity in the United States. Recent work by feminist historians has revealed that women were interested in a broad range of issues at the turn of the twentieth century. The American Left addressed such issues as...

Nuclear and chloroplast diversity of Pacific Northwest wheat (Triticum aestivum) breeding germplasm

Creator:: Edwards, Melanie Love
Abstract:: Wheat breeders must effectively maintain and manage existing genetic diversity in order to continue the development of superior genotypes. It is therefore fundamental that the genetic relationships and diversity within the germplasm pools be thoroughly characterized and understood. Recently, DNA-based markers have provided powerful tools for genetic diversity analysis. This...

Sensitivity of wheat genotypes to a toxic fraction produced by Cephalosporium gramineum and correlation with disease susceptibility

Creator:: Rahman, Mahfuzur
Abstract:: 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 stubble mulch is practiced to maintain soil moisture and prevent erosion. As cultural control of the disease is infeasible and no fungicides...

Pyramiding quantitative trait loci conditioning partial resistance to Sclerotinia sclerotiorum in bush blue lake green beans (Phaseolus vulgaris)

Creator:: Barrett, Miles Andrew
Abstract:: Sclerotinia sclerotiorum (Lib.) de Bary is a necrotrophic pathogen capable of causing white mold, a severe disease in common bean. White mold is of particular concern to the Oregon snap bean processing industry, where processors allow less than 3% incidence in harvested shipments. Breeding for white mold resistance in beans...
