Understanding the mechanism of resistance, relative fitness and competitiveness of herbicide resistant biotypes is important to predict population dynamics and to establish resistance management strategies. This study was conducted to determine the level of resistance to acetolactate synthase (ALS) inhibitors and the mechanism of resistance of ALS-inhibitor resistant downy brome...
Results from vegetation management trials involving horticultural crops conducted during the past year are compiled and reported by faculty members of the Oregon Agricultural Experiment Station, the Oregon State Extension Service, and colleagues who cooperated from adjacent states along with local enterprises. This work was conducted throughout Oregon and involved...
Polybenzimidazoles were synthesized from 3, 3', 4, 4'-tetraminobiphenyl
(diaminobenzidine, or DAB) with orthoesters, carboxylic acid derivatives (an ester and
an acid) and with m-benzenedialdehyde. The products were of low molecular weight,
as evidenced by low inherent viscosity, except in the case of the dialdehyde plus DAB.
The product of that...
Recent turbulence measurements over a small bank on the continental shelf off Oregon reveal a previously undetected site for intense mixing of the coastal ocean. The flow is hydraulically controlled and turbulence diffusivities over the bank are more than 100 times greater than estimates made on the shelf away from...
Transcription factor (TF) genes were modified endogenously to include epitope tags for identification of TF protein binding sites by Chromatin Immunoprecipitation (ChIP), followed by high throughput sequencing. We used RNA-sequencing in carbon sources of sucrose, butyrate, and oleate in far-1, far-2, and a double far-1; far-2 mutant to find transcripts...
The discovery of the methylerythritol phosphate pathway (the MEP pathway) as an alternate pathway for isoprenoid biosynthesis in some organisms including most bacteria, malarial parasites and plants, but not in animals, has stimulated extensive studies in this area. Research has revealed the potential of finding novel antibacterials, antimalarial drugs, and...
We achieve a series of distinct broadband third-harmonic generation (THG) signals at the amorphous glass–air interface attributed to third-order and cascaded third-order nonlinear processes. A novel THG laser sideband arises
from cascaded interaction between fundamental pulses and the cascaded four-wave mixing signals. The spatially
separated THG sidebands with distinct spectral...
Total length and biomass of fungal mycelium in the soil of a young Douglas-fir stand in the central Oregon Coast Range were estimated over 27 months with the agar-film technique. In a second study, phenology and taxonomy of hypogeous (belowground) sporocarps were studied over 32 months in a nearby, young...
