Silencing of Agrobacterium tumefaciens T-DNA oncogenes by cosuppression

Creator:: Lee, Hyewon
Abstract:: We have developed crown-gall resistant transgenic plants capable of suppressing Agrobacterium tumefaciens T-DNA oncogenes. Crown gall tumors result from overproduction of auxin and cytokinin in plant cells transformed by A. tumefaciens. High phytohormone levels result from expression of two auxin biosynthetic genes, tryptophan monooxygenase (iaaM) and indole acetamide hydrolase (iaaH),...

The economic feasibility of soybean production in Oregon

Creator:: Holst, David
Abstract:: Commercial production of soybeans in Oregon has been limited. In 1977, less than 1,500 acres were grown, primarily in the Columbia Basin area. However, interest in soybeans as a possible "new crop" for Oregon has arisen because of the (1) recent strong soybean price, (2) the high cost of transporting...

Is Resistance Futile: Examining Fitness Costs Associated with QoI Resistance in E. necator

Creator:: Newbold, Chelsea L.
Abstract:: Quinone outside Inhibitor (QOI) fungicides are one of the most widely used fungicide classes (FRAC 11) in the world. This popularity is the result of their ability to effectively manage a wide array of economically important pathogen species on a broad range of crops. While having mostly preventative activity, some...

Grape Powdery Mildew Management: The Interaction Between Inflorescence Stage and Fungicide Chemistry

Creator:: Warneke, Brent W.
Abstract:: Grape powdery mildew (GPM, causal agent Erysiphe necator) is the most economically important disease of grapevine in the Western U.S. Low levels of GPM infection on clusters (1-5%) can negatively affect wine sensory quality, so intensive fungicide programs are common. This may lead to problems like excessive fungicide use and...

Understanding sporulation and dissemination of Podosphaera macularis, hop powdery mildew

Creator:: Peetz, Amy B.
Abstract:: Podosphaera macularis causes one of the most important diseases, powdery mildew, of Humulus lupulus (hop). If left unmanaged, hop powdery mildew can cause total crop loss due to disease or browning of hop cones rendering the cones unmarketable to buyers. The Hop Powdery Mildew Infection Risk Index (HOPS) is heavily...

Epidemiology of grape powdery mildew, Uncinula necator, in the Willamette Valley

Creator:: Hall, Tyrone W.
Abstract:: An important disease of Vitis vinifera production in Oregon and all other commercial growing regions is powdery mildew of grape, caused by the obligate fungal pathogen Uncinula necator (Schwein.) Burril. Grape production can be characterized as a long-term investment in the establishment and maintenance of the vineyard. Establishment times have...

Evaluation of a potential Chylamydia psittaci vaccine candidate using recombinant vaccinia virus encoding the infection-specific C. psittaci GPIC proteins IncA and TroA

Creator:: Werth, Eric P.
Abstract:: Members of the family Chlamydiae cause a wide range of diseases. Chlamydia trachomatis and C. pneumoniae are most commonly associated with human disease. C. psittaci and C. pecorum are largely animal pathogens, although C. psittaci can cause pneumonia in the elderly and immunocompromised. A vaccine against these pathogens is desirable,...
