Mycorrhizal and other root endophytic fungi of lupines in the Pacific Northwest

Creator:: O'Dell, Thomas E.
Abstract:: We investigated the root endophytic fungi of lupine using four approaches: (1) occurrence of fungal colonization in field-collected roots; (2) growth response of L. latifolius to inoculation with two types of fungi; (3) structure of root colonizations of Pinus and Lupinus by Phialocephala fortinii, a septate endophytic fungus of lupine;...

Studies to facilitate reintroduction of golden paintbrush (Castilleja levisecta) to the Willamette Valley, Oregon

Creator:: Lawrence, Beth A.
Abstract:: Golden paintbrush (Castilleja levisecta Greenman) historically inhabited the prairies of the Willamette Valley, Oregon. However, this Pacific Northwest endemic is currently restricted to eleven sites in the Puget Trough of Washington and British Columbia. Recovery criteria call for the establishment of new populations throughout the species historic range, including the...

A biochemical analysis of the interaction of victorin and oats

Creator:: Navarre, Duroy A.
Abstract:: Victoria blight of oats is caused by the fungus Cochhobolus victoriae. This fungus is pathogenic due to its ability to produce the host-selective toxin victorin. Previously, a 100-kD protein that binds victorin in vivo only in susceptible genotypes was identified as the P protein of the glycine decarboxylase complex (GDC)....

Quantitative Trait Loci Associated with the Tocochromanol (Vitamin E) Pathway in Barley

Creator:: Graebner, Ryan C., Wise, Mitchell, Cuesta-Marcos, Alfonso, Geniza, Matthew, Blake, Tom, Blake, Victoria C., Butler, Joshua, Chao, Shiaoman, Hole, David J., Horsley, Rich, Jaiswal, Pankaj, Obert, Don, Smith, Kevin P., Ullrich, Steven, and Hayes, Patrick M.
Abstract:: The Genome-Wide Association Studies approach was used to detect Quantitative Trait Loci associated with tocochromanol concentrations using a panel of 1,466 barley accessions. All major tocochromanol types- α-, β-, δ-, γ-tocopherol and tocotrienol- were assayed. We found 13 single nucleotide polymorphisms associated with the concentration of one or more of...

Is Resistance Futile: Examining Fitness Costs Associated with QoI Resistance in E. necator

Creator:: Newbold, Chelsea L.
Abstract:: Quinone outside Inhibitor (QOI) fungicides are one of the most widely used fungicide classes (FRAC 11) in the world. This popularity is the result of their ability to effectively manage a wide array of economically important pathogen species on a broad range of crops. While having mostly preventative activity, some...

Studies on viruses isolated from roses with rose mosaic symptoms

Creator:: Watson, Thomas Ray
Abstract:: Previous work on the rose mosaic virus has produced uncertainty concerning the identity and properties of this virus. This work was undertaken to help establish the true identity of the virus and to determine some of its properties. A mechanically transmissible virus associated with rose mosaic virus disease of Rosa...

Photoinduction of kaurene synthetase, an enzyme of the gibberellin biosynthetic pathway, during de-etiolation of pea seedlings

Creator:: Gomez-Navarrete, Gladys
Abstract:: Previous investigations have shown that the enzymes catalyzing the biosynthesis of the gibberellin-type of hormones from mevalonic acid in plants are compartmentalized in plastids. Moreover, the activity of one of the key enzymes in the biosynthetic sequence, kaurene synthetase, exhibits markedly enhanced activity when a dark-grown pea seedling undergoes de-etiolation...

Using local climate to explain temporal variation in rare plant populations

Creator:: Pfingsten, Ian A.
Abstract:: Increased temperatures due to anthropogenic-induced climate change may raise the threat of extinction for taxa with sessile life histories (e.g., plants) in the near future. Linking climate change models to demographic models may provide useful insights into the potential effects of environmental changes on rare plants, and therefore aid in...

Potato virus X : detection and inter-relationship with Verticillium dahliae and Colletotrichum atramentarium

Creator:: Goodell, Jody Jellison
Abstract:: Preliminary studies were run to determine the sensitivity and reliability of enzyme-linked immunosorbent assay (ELISA) for the detection of potato virus X (PVX). ELISA was found to be capable of detecting PVX in tobacco at a 1:3333 sample dilution. The reliability of ELISA for the detection of PVX in potato...

Physiology of senescence of the shoot apex in Pisum sativum L.

Creator:: Ecklund, Paul Richard, 1941-
Abstract:: Shoot apex senescence is defined as the collective progressive and deteriorative processes which ultimately terminate the functional life of the shoot apex. Senescence of shoot apices of Pisum sativum L. 'Alaska' as measured by cessation of stem elongation was delayed by removal of flowers and by treatment with gibberellin A₃...
