Butterfly bush (Buddleja davidii), an ornamental native to China, is an invasive species in Oregon and many other areas. In Oregon, butterfly bush invades disturbed areas, particularly riparian areas. The Oregon nursery industry has the highest farm-gate value of all agricultural commodities and butterfly bush is a significant plant to...
The highly conserved multi-protein mismatch repair (MMR) system is known for its ability to correct post replication errors in genomic DNA. A hallmark of MMR deficiency in all organisms is microsatellite instability. The initiating proteins in the eukaryotic MMR system are hetrodimers formed with an integral MSH2 subunit and one...
Collaboration is crucial when advancing in scientific research. One person cannot
study all aspects of a system. That is why it is important for the scientific community to
communicate with each other and stay updated on research being conducted in other labs
around the world. In my research, I was...
Motivation: It can take considerable amounts of time and effort to use existing computational tools to analyze a small RNA sequence for the purpose of determining if it is characteristic of microRNA. It is similarly tedious to search for homologs to known microRNA sequences in the rapidly growing collection of...
Studies were conducted to assess influencing the effectiveness of sheep for grazing control of false brome (Brachypodium sylvaticum) an invasive grass species. Orphan lambs were exposed to false brome via grass extract in their milk and naturally reared lambs were exposed by grazing dense stands of false brome with their...
Polycyclic aromatic hydrocarbons (PAHs) are a class of usually planar
compounds consisting of fused aromatic rings that are formed by the incomplete
combustion of organic materials. PAHs are ubiquitous in the environment, coming from
a number of sources, such as cigarette smoke, the burning of wood for residential heating,
and...
Sarcocystis neurona is the 1responsible for the disease Equine Protozoal Myeloencephalitis (EPM). Exposure rates to S. neurona across the United States is about 50%, yet only about 2% of exposed horses develop EPM. The cell-mediated immune (CMI) response is hypothesized to be important for protective immunity against this disease. The...
Biological control is the action of predators, parasitoids, or pathogens to maintain
a pest organism's population at lower numbers than would occur in the absence of the
agent. Entomopathogenic nematodes can be used as biological control agents for insect
pests. These nematodes infect insects and release a toxic bacterium that...
Auxin and ethylene regulate many important aspects of plant growth and development and are
essential to the plants survival. They help regulate such diverse processes as cell elongation,
growth of adventitious roots, fruit growth, germination, and a variety of other processes. Few
studies have examined how the hormones auxin and...
A lexicon to define the sensory properties of melted Cheddar cheese was created
using a trained descriptive panel. The lexicon characterized appearance (surface rupture,
meltedness, oiliness, and edge browning) and texture (stringiness, stretchiness,
springiness, firmness, toothpull, smoothness, cohesiveness, denseness, and chewiness).
Three brands of commercially available shredded Cheddar cheese were...
Relationships among soil pH, redox potential, and ferrous iron content data obtained from
various field and lab methods were determined, with the following 4 objectives:
1.) Compare pH values obtained in the field to those obtained in the lab
2.) Evaluate different methods to measure pH in field
3.) Determine...
The following paper is an objective view on the viability of growing the truffle Tuber melanosporum in the Willamette Valley. Included in this study are the history of the truffle, biological cycle, habitat description, method of cultivation and an enterprise budget for commercial production in the Willamette Valley. The truffle,...
The psychoactive component of marijuana, A9-tetrahydrocannabinol (THC), is known
to have effects in humans that are mediated by the cannabinoid receptor (CB 1). Although a great deal of research has been done to confirm the interaction of exogenous cannabinoids with the CB 1 receptor, little is known about the receptor's...
Legislation to reduce the annual limit of field burning in Oregon has led to increased study of
alternative non-thermal grass-seed management methods. Of these methods, non-thermal residue
management, in combination with crop rotations and different tillage practices, offer potential to
equal or exceed crop production of conventional thermal production systems....
While previous experiments on the physiological activity of primary and secondary cyanolichens have been done, an analysis of photomorphs has never been attempted. Photomorphs of Peltigera britannica (Gyelnik) Hotan-Hartw. & Tonsberg were studied to compare the physiological response of a primary cyanolichen to an additional symbiotic partner (green algea) while...
Llama reproductive physiology is unique when compared with other livestock species. Llamas carry 95-98% of all pregnancies in the left uterine horn. It is believed that there is a physiological difference between the uterine horns that contributes to this phenomenon. This study examined the uterine environment for protease and protease...
Cell lines deficient in certain genes of the DNA mismatch repair (MMR) system show a marked resistance to the cell killing or apoptotic effects of DNA alkylating agents. The molecular mechanism for this resistance is not yet understood, but is currently of great interest because of the recent use of...
The diageotropica (dgt) mutation has been proposed to affect either auxin
perception or responsiveness in tomato plants. Auxins and cytokinins are plant
growth regulators known to interact with each other via a variety of mechanisms.
Here, we report the interactions of auxins and cytokinins in VFN8 wild-type and
dgt mutant...
This study examined the management situation for the Columbiaroot-knot nematode (Meloidogyne chitwoodi) in potato, using an approach with systems thinking and interactive meetings. The focus of current research for control of this nematode was evaluated. Control practices include crop rotation, and this study also evaluated popcorn cultivars for their potential...
