The goal of this project is to understand the interaction between arbuscular mycorrhizal (AM) fungi (phylum Glomeromycota) and endosymbiotic bacteria that reside in their hyphae and spores. AM fungi and their endobacteria are components of a complex symbiotic association that also includes the majority of terrestrial plants and may be one of the most common multi-partner symbioses on the planet. AM fungi colonize roots of land plants and assist in the uptake of mineral nutrients to the plant in exchange for plant-assimilated carbon. We found that: (1) the Ca.
A web-based, apple Integrated Pest Management (IPM) decision support system was developed to facilitate pest management decisions. The system tracks seasonal development of insect pests using degree day (DD) developmental models. DD models and historical records are used to calculate tree phenological stage, pest stage, status and management advice. When a spray is recommended, a pesticide filter helps identify appropriate materials according to efficacy and type of management program. Predictions can be refined and adjusted by user-entered information obtained through field monitoring.
The use of milk protein preparations obtained by membrane separation is receiving increasing interest from the dairy industry, as well as the food industry at large. One of the challenges these industries face is the lack of knowledge regarding the behavior of these protein preparations during processing. We have evaluated the rheological properties and processing stability of micellar casein concentrates obtained by membrane separation.
We are developing a multi-pathogen detection system for the rapid identification of known and emerging pathogens of solanaceous crop plants (potato, tomato, pepper and eggplant).
Pulsed light treatment is a new, non-heat method of microbial inactivation that can be used to increase the safety of a variety of foods. Since it is a light-based treatment, the optical properties, shape and size of the substrate, and relative location to the light source can limit the effectiveness and uniformity of the treatment. We developed a systematic approach for understanding the spatial distribution of inactivation in a substrate of known optical properties.
The goal of the proposed project is to provide international research training experience in various disciplines within the biomedical field to undergraduate and graduate students. This training has the purpose of creating awareness of opportunities and motivating students to pursue professional careers in the health sciences, which could contribute to addressing issues and providing solutions to minority health disparities.
Approximately 70 million metric tons of apple fruit are produced annually worldwide in 90 countries. However, the diversity of production is low as > 60% of fruit (excluding China) is produced by as few as five cultivars: Golden Delicious, Delicious, Gala, Fuji and Granny Smith. Many factors may have contributed to such low diversity in apple production, but lacking of superior new apple varieties is clearly one of the major factors. Apple is a perennial woody species with a long juvenile phase before fruiting.
The general goal of this research is to understand the hormonal regulation of fruit development, primarily using tomato fruit development as a model experimental system, and with a particular emphasis on auxin homeostasis and signaling
Spinal cord injury (SCI) results in two spinal problems. First, the neural networks that control movement in the spinal cord lose their drive from the brain. Second, the neurons in the spinal cord below the lesion start to alter their properties due to the loss of input. We are studying this second problem by analyzing the properties of identified spinal interneurons after spinal cord injury, and whether replacement therapy with serotonergic agonists can prevent these changes.
I provide education for individuals who are interested in wine grape production. From workshops to group video-conference meetings, my team and I strive to encourage would-be wine-grape growers to make sound economic and viticulture decisions.
