We evaluated the extent to which the average metabolic activity of open ocean bacterioplankton
changed during 2 to 3 d incubations of 1 μm filtered seawater at in situ temperature. Indices
of bacterial activity during incubation experiments were compared to those of in situ bacterioplankton,
which were repeatedly sampled at...
Alternating temperature (22°C / -1°C) pretreatments were effective for
increasing cold hardiness and recovery of cryopreserved meristems. Combining low
temperature pretreatment with abscisic acid (ABA) or sucrose treatments reduced the
time required for optimal cold hardiness of meristems. Desiccation tolerance was
directly correlated with increased cold hardiness and recovery of...
Evaporation was studied along the Middle Fork of the John Day River in northeastern Oregon. Evaporation pans and various meteorological sensors recorded data at nine sites during the summer of 1998; measurements were made at each site over a 3-4 day period. A Dalton-type evaporation model was produced using water...
In an effort to understand the basis for sulfite detoxification in S. cerevisiae,
the functions of two genes were analyzed. SSU1, which encodes a plasma membrane
protein, was found to be required for efficient sulfite efflux. FZFl-4, a dominant
allele of a transcriptional activator of SSUl, was also found to...
Virus contamination in a potato breeding program can seriously
disrupt the variety development process. Experiments were conducted
from 1989 through 1993 to: evaluate the extent to which Potato
Leafroll Virus (PLRV) and Potato Virus Y (PVY) can invade a breeding
program, determine viral spread within hills and within individual
tubers,...
Oregon's watershed councils are local, non-regulatory, collaborative forums charged
with the recovery of endangered salmon and improving water quality under The Oregon Plan for Salmon and Watersheds. Private forest landowners, given their prominence is owning riparian areas, are central to success of these efforts. Using a statewide survey of watershed...
The increased US domestic production of surimi from the US Pacific Coast after 1977 is a major consequence of the US's extended fisheries jurisdiction to 200 nautical miles. It is only one consequence, however, whose nature can best be understood by examining the surimi market in the context of what...
The pigments of blackberry fruit were investigated by analytical and preparative high performance liquid chromatography (HPLC) to characterize anthocyanin patterns in commercially important blackberry (Rubus eubatus) cultivars and selections. Five anthocyanin pigments were detected in Evergreen blackberry and they were identified as cyanidin-3-glucoside, cyanidin-3-rutinoside, pentosecyanidin derivative and two acylated cyanidin...
