Rhizopus microsporus is a globally ubiquitous opportunistic human and plant pathogen that is known to harbor endosymbiotic bacteria. Differences between populations of clinical and environmental R. microsporus isolates have yet to be assessed on a global scale. Whole-genome sequence data were used to explore fungal biology and to assess potential...
This thesis explore the effects of China's Grassland Contract policy on sedentary and mobile Inner Mongolian pastoralists' attitudes towards cooperation, current grassland management practices, and the future viability of livestock herding in New Barag Right Banner, Inner Mongolia. Semi-structured interviews, a scaled survey instrument, and participant observation were carried out...
Diverse pastures containing multiple species help extend the grazing season and reduce the reliance on one or two species to meet all the nutritional requirements of livestock. Planting pasture species in spatially separated adjacent strips can increase the proportion of pasture plants with certain agronomic and nutritional attributes such as...
Vineyards in Oregon’s Willamette Valley are predominately planted to perennial grass cover in the alleyways of vineyards. This grass cover is grown to increase worker and equipment traction, as well as reduce erosion and manage vine vegetative vigor. However, with increasing frequencies of drought and warming temperatures, the use of...
Cellulosic ethanol production for transportation fuel is one source to help satisfy the increasing worldwide demand for energy and depletion of the fossil fuel supply. Evaluating potential production from plants and waste in Oregon, Washington and Idaho is the purpose of this study. Reed Canary grass, Annual Ryegrass, wheat straw,...
A sensitive assay for the analysis of contaminating segments
in pseudorecombinants constructed from a seed-transmissible (CVM-Pg)
and a non-seed-transmissible (CMV-Le) strain of cucumber mosaic
virus was developed using partial RNase T₁ digestion. Isolated
genomic RNA segments produced unique digestion patterns when 3'-
end labeled, treated with RNase T₁, and subjected...
Many investigators have suggested that current photosynthate
supply can limit adventitious root formation on leafy cuttings.
Accordingly, studies were undertaken to determine the effects of
altering photosynthesis and carbohydrate levels on adventitious root
formation by leafy cuttings of a number of different species.
Pea cuttings rooted at high CO₂ (1800...
Meadowfoam has been identified as a potential oilseed crop for
production on poorly drained soils in areas with cool, moist winters.
The effects of N fertilizer on meadowfoam (Limnanthes alba Benth.)
have been studied in Oregon and Maryland, but the results have not
been consistent with respect to the effects...
Seed vigor tests have been developed to evaluate the relative ability of seed lots to produce stands of seedlings in the field. Some workers have suggested the possibility of differentiating vigor levels by germinating seeds under osmotic stress, but have not conducted field trials to evaluate the usefulness of the...
Seed-Lab, is a software system for managing seed laboratory information. It was developed at the Oregon State University Seed Testing Laboratory. Seed-Lab was built around a database development package Revelation, which provides its own programming language.
Seed-Lab shields the user from the complexities of database management by supporting menu driven...
