Abstract:: Previous research suggests a link between litter size in ewes and differential excretion of fecal hormones. An accurate test for fetal number would be useful to sheep producers and a fecal hormone response could be utilized in such a test. Fifteen previously categorized fecal hormones were analyzed within fecal samples...

Creator:: Shaffar, Sarah J.
Abstract:: Little is known about Frankia, a gram-positive, nitrogen-fixing bacterium, because of the difficulty associated with isolating pure cultures. This nitrogen-fixing symbiosis involves Frankia and the roots of actinorhizal host plants belonging to eight plant families and 25 genera. These plants are important pioneer species traditionally found in nitrogen-poor soils and....

Creator:: Obermeyer, Angela L.
Abstract:: Horticultural and nursery crops are the leading agricultural commodity in Oregon. Among currently grown nursery plants, Verbena x hybrida is a staple ornamental. It is grown and shipped worldwide, thus requiring a high level of certainty concerning the plants’ health and potential viability. V. x hybrida cultivars have been infected...

Creator:: Zitzewitz, Jarislav W. von
Abstract:: The development of winter 6-row malting barley varieties is an objective of the OSU program. The program's winter germplasm is quite susceptible to Barley Yellow Dwarf Virus (BYDV). The program recently released the spring 2-row variety Orca, which carries the Yd2 gene for BYDV resistance. The objective of this project...

Creator:: Hall, Kelly P.
Abstract:: 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...

Creator:: Cardwell, Derek
Abstract:: 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...

Creator:: Brodeur, Timothy J.
Abstract:: 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...
