Northwest cherry cultivars including Prunus avium 'Bing', Prunus avium 'Rainier', Prunus avium 'Royal Anne' and Prunus cerasus 'Montmorency' were separated into epidermal tissue, flesh and pit and cryogenically milled with liquid nitrogen. These samples as well as whole samples from each variety were extracted with acetone followed by a chloroform...
Chlamydiae are obligate intracellular bacterial pathogens with a unique biphasic life cycle that consists of an infectious but non-dividing form, called elementary bodies (EB), and a noninfectious but metabolically active form, called reticulate bodies (RB). Chlamydia has an unusual process of cell division of which still remains uncharacterized subject matter;...
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...
Indole-3-carbinol (13C), a metabolite of glucobrassicin, is found in cruciferous vegetables. It is able to act as an inhibitor or promoter of carcinogenesis depending on the species, the carcinogen and when it is given in relation to the carcinogen. This is probably due to the fact that it reacts in...
Kincaid's lupine (Lupinus sulphureus ssp. kincaidii [Smith] Phillips) is a federally listed Threatened plant of Willamette Valley prairies. Both low reproduction, due to seed coat dormancy, and competition from invasive plants may threaten the longterm viability of this species. In separate studies, I investigated seed germination and an invasive species...
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...
Deforestation, intensive agriculture and chemical use all can cause long-lastingn negative impacts on soil health. With all the vital functions that soils perform and the potential for further soil degradation, it is important that standards of soil quality or soil health be implemented. Soil aggregation is considered to be a...
