Preventing crown gall disease using oncogene silencing or VirE1-expressing transgenics

Creator:: Humann, Jodi L.
Abstract:: Crown gall disease is caused by the ubiquitous soil bacterium Agrobacterium tumefaciens which transfers a portion if DNA (T-DNA) into the plant cell. Preventing infection by using the biocontrol strain Agrobacterium radiobacter K84 is currently the only defense for crown gall. Two different resistance strategies were examined in this work....

Silencing the Agrobacterium tumefaciens oncogenes

Creator:: Pitrak, Jennifer
Abstract:: Crown gall disease is an agricultural problem caused by the soil-borne bacterium, Agrobacterium tumefaciens. A. tumefaciens oncogenes cause transformed plant cells to overproduce the hormones, auxin and cytokinin. High hormone levels cause unorganized plant cell growth resulting in a gall. Control of crown gall disease is difficult because after plant...

Phytosanitation of Douglas-fir (Pseudotsuga menziesii) logs to mitigate the risk of artificially disseminating Phytophthora ramorum within the global trade of timber

Creator:: Hulbert, Joseph M.
Abstract:: Phytophthora ramorum is a plant pathogen that was accidentally introduced to the United States. This invasive microorganism has killed over a million trees in California and Oregon, and continues to spread to new areas. Diseased areas have been nationally quarantined to prevent further spread and more than ninety countries include...

Application of probiotics and green tea extract in post-harvest processes of Pacific oysters (Crassostrea gigas) for reducing Vibrio parahaemolyticus and extending shelf life

Creator:: Xi, Dunyu
Abstract:: Vibrio parahaemolyticus is a human pathogen which is prevalent in marine environment. Consumption of raw or undercooked seafood contaminated with V. parahaemolyticus can cause foodborne illness. This study investigated the application of probiotics in depuration for reducing V. parahaemolyticus in raw Pacific oysters (Crassostrea gigas) and the utilization of green...

Influence of Processing Parameters on the Inactivation of Salmonella spp. During the Cooking Step of Jerky Production Using a Commercial-Scale Dehydrator

Creator:: Minarsich, Joey
Abstract:: United States Department of Agriculture-Food Safety and Inspection Service (USDA-FSIS) guidelines for beef jerky processing support producers' ability to satisfy the performance standard requirements for achieving a 5-log reduction in Salmonella and E. coli O157:H7. The first compliance guide for jerky processors was created in response to several Salmonella outbreaks...

Factors Affecting the Efficacy of Depuration for Decreasing Vibrio parahaemolyticus Contamination in Pacific Oysters (Crassostrea gigas)

Creator:: Hou, Yishu
Abstract:: Vibrio parahaemolyticus is a foodborne pathogen recognized as the leading cause of acute gastroenteritis associated with consumption of raw and undercooked seafood, particularly raw oysters, with major symptoms of nausea, vomiting, abdominal cramps and diarrhea. It is estimated that 45,000 cases of V. parahaemolyticus infection occur each year in the...

Bacillus subtilis endospore coat protein solubilization methods for studying effects of high pressure precessing

Creator:: Gandhi, Kalpesh K.
Abstract:: Spores of foodborne pathogens such as Clostridium botulinum, Clostridium perfringens and Bacillus cereus are widely distributed in nature. Presence of those spores in food products, particularly C. botulinum spores in vacuum packed, ready-to-eat low-acid products, is a great safety concern. The research here described is a first effort towards understanding...
