Correspondence of soil properties and classification units with sagebrush communities in southeastern Oregon

Creator:: Lentz, Rodrick David
Abstract:: This research employed multivariate analytical techniques to statistically examine the relationship between individual soillandscape units (SLUs) in Southeastern Oregon and their associated sagebrush communities. The objective was to determine if soil properties between SLUs differed, describe the variation, and verify that these differences were reflected in the taxonomic class of...

Sheep grazing in Douglas-fir plantations of Oregon's Coast Range and its impact on big game habitat

Creator:: Rhodes, Bruce Douglas
Abstract:: As part of investigations to evaluate the suitability of sheep grazing in Douglas-fir (Pseudotsuga menziesii) plantations of Oregon's Coast Range, this research was designed to evaluate the effectiveness of sheep grazing in suppressing unwanted vegetation, determine seasonal variations in forage quality, and investigate the impact of sheep grazing on big...

Nutritional and managerial considerations for wintering beef cattle in the northern Great Basin

Creator:: Brandyberry, Steven D.
Abstract:: A study was conducted to determine effects of year and season on diet quality of beef cattle grazing northern Great Basin rangelands from 1990 to 1993. Forage quality was high early in the growing season, then declined as seasons progressed (P<.05). Plant chemical composition was higher early in the growing...

Purification of 2,5-dihydroxyacetanilide epoxidase and mechanism of hydroquinone epoxidases

Creator:: Kirchmeier, Marc J.
Abstract:: 2,5-dihydroxyacetanilide epoxidase from Streptomyces LL-C10037 (DHAE I) catalyzes the epoxidation of hydroquinone 4, to form epoxyquinone 7. DHAE I has been purified to homogeneity, with an overall purification factor greater than 23,000. N-terminal and internal amino acid sequences have been obtained from the purified enzyme so that the epoxidase gene...

Marker development, genome mapping, and cloning of candidate disease resistance genes in sunflower, Helianthus annuus L

Creator:: Gedil, Melaku Ayele
Abstract:: The level of polymorphisms of many biochemical and DNA markers are low in cultivated sunflower (Helianthus annuus L.). The number of mapped public DNA markers is limited. Molecular markers have not been developed for the most important diseases of sunflower, such as downy mildew. The objectives of this study were...

Studies on the biosynthesis of the streptolidine moiety of streptothricin F

Creator:: Wityak, John
Abstract:: The loss of all deuterium labels from previous feedings of [2-²H]-, [3,3-²H₂]-, and [2,3,3-²H₃]arginines had indicated the possible intermediacy of β-hydroxy- and β-ketoarginine (30 and 31, respectively) in the biosynthesis of the streptolidine portion of streptothricin F (la). In order to confirm or refute this evidence, D,L-[2,3,3,5,5-²H₅]- arginine (32) was...

Molecular mechanisms underlying the high oleic acid phenotype in sunflower

Creator:: Schuppert, Gunnar Felix
Abstract:: Wildtype sunflower typically produces 12-24% oleic acid (18:1) and 70-82% linoleic acid (18:2). High-oleic sunflower, by contrast, produces up to 80-94% oleic acid. The monounsaturated oleic acid has a greater oxidative stability than the polyunsaturated linoleic acid, predominant in wildtype sunflower, and has greater nutritional benefits than polyunsaturated and saturated...
