Physiological responses of creeping red fescue to stubble management and plant growth regulators

Creator:: Meints, Paul David
Abstract:: Legislation to reduce open field burning in grass seed fields within the Willamette valley of western Oregon changed established production practices. In the creeping grasses such as Kentucky bluegrass (Poa pratensis L.) and creeping red fescue (Festuca rubra L.) non-thermal management resulted in reduced yield. Studies were conducted to examine...

Development, characterization and application of polyclonal antibodies against ovine adipocytes for body fat reduction by passive immunization

Creator:: Nassar, Abdul-Rahman Hassan
Abstract:: Three experiments were conducted (1) to develop and characterize polyclonal antibodies against ovine adipocyte plasma membranes (APM), (2) to evaluate the effect of administering the developed antibodies to lambs on lamb growth and carcass characteristics, and (3) to investigate the possibility of using the developed antibodies to identify antigenic components...

Puberty development and reproductive performance in beef heifers fed rations supplemented with Oregon by-product feeds

Creator:: Oswald, Keely E.
Abstract:: In the majority of management scenarios, it is imperative that beef replacement heifers calve at two years of age. In order to achieve this goal, yearling heifers should reach 60 to 65% of their mature body weight by 13 months of age. Feed costs represent 75 to 80% of the...

Trinexapac-ethyl and open-field burning in creeping red fescue (Festuca rubra L.) seed production in the Willamette Valley

Creator:: Zapiola, Maria Luz
Abstract:: Open-field burning has been an effective, economical, and widespread method of post-harvest residue management in creeping red fescue seed production in the Willamette Valley since the late 1940s. However, the use of field burning has been legislatively restricted due to air quality and safety issues. The foliar-applied plant growth regulator...

Auxin and cytokinin interaction in tomato (Lycopersicon esculentum Mill.)

Creator:: Coenen, Catharina
Abstract:: The phytohormones auxin and cytokinin control plant development through a complex network of interactions which include synergistic, additive, and opposite effects whose mechanisms are unknown. The auxin-insensitive diageotropica (dgt) mutant provided a tool to dissect the relationship between auxin- and cytokinin-induced responses in tomato. Morphological, physiological, and molecular data support...

Genome-enabled discovery and characterization of type III effector-encoding genes of plant symbiotic bacteria

Creator:: Kimbrel, Jeffrey A.
Abstract:: Symbiosis is the close and protracted interaction between organisms. The molecular interactions that occur during symbiosis are complex with multiple barriers that must be overcome. Many Gram-negative, host-associated bacteria use a type III secretion system to mediate associations with their eukaryotic hosts. This secretion system is a specialized apparatus for...

The growth of wild-type and genetically-marked strains of Tilletia caries and T. controversa in susceptible and resistant wheat cultivars

Creator:: Trail, Frances
Abstract:: The objective of this study was to provide basic information on the interaction of the bunt fungi Tilletia caries and T. controversa with their host, Triticum aestivum. Studies on the ability of haploid strains to colonize wheat heads provided the basis for experiments in which haploid strains were crossed in...

Residue management and yield characteristics of fine fescue seed crops

Creator:: Schumacher, Derek David
Abstract:: Chewings fescue [Festuca rubra L. subsp. fallax (Thuill.) Nyman] is a desired turfgrass with dense sod forming capabilities and superior shade tolerance. Thermal residue management (open-field burning) has traditionally been used to remove post-harvest residue and maintain seed yield over the life of the stand. However, alternative non-thermal residue management...

Ryegrass fluorescence expression during three generations of seed increase and its heritability among half-sib families

Creator:: Floyd, Donald J.
Abstract:: Seedling root fluorescence (SRF) has been used as a test in the USA since 1941 to discriminate Italian ryegrass (Lolium multiflorum Lam.) from perennial ryegrass (L. perenne L.). Generally, roots of Italian ryegrass fluorescece when exposed to ultraviolet light, while roots of perennial ryegrass do not. Presence of fluorescent seedlings...

Structural and functional analysis of the 57 kDa protein produced by the fish pathogen, Renibacterium salmoninarum

Creator:: Wiens, Gregory D.
Abstract:: Little is known about the virulence factors of Renibacterium salmoninarum, the causative agent of salmonid bacterial kidney disease. The predominant protein produced by R. salmoninarum in broth culture or during infection is a 57/58 kDa protein (p57) which is associated with strain virulence. In this study monoclonal antibodies (MAbs) to...
