A working group of applied and basic researchers has been established to coordinate research and extension regarding a highly damaging new disease of boxwood. University and USDA-ARS workers studying disease management and epidemiology, pathogen survival and genetics are collaborating closely to develop a highly focused effort resulting in new information and its dissemination.
The sensory representation of the external chemical world in the brain is a translation of chemical features into patterns of brain activity. It is the nature these patterns—how that are established by stimulant patterns, how they vary in a population, and ultimately how they interact with other brain functions, e.g. emotions (joy) or behavior (buying wine)—that is the object of our research. We study aroma perception in order to provide information about food composition to producers that will allow them to produce likable, healthy and more profitable products.
The viticulture and enology steering committee created a quarterly electronic newsletter, Appellation Cornell, to provide in-depth research articles written for laypersons, as well as faculty profiles, student profiles, industry profiles, and brief articles to highlight research, extension, and teaching activities of Cornell's Viticulture and Enology Program to a national and international audience. In its first year, readership comprised 1000 to 1500 online subscribers in 45 states, three Canadian provinces, Europe, Australia, and New Zealand. Fifty articles were published in 2010.
Environmental change affects all organisms either directly by physiological effects or indirectly by influencing the organisms with which they interact. My work investigates how ecological interactions are altered and how organisms evolve in response to these changes. The objective is to understand the trajectory and rate of these responses.
Powdery mildew is one of the world's most destructive diseases of grapevines. We know that infection of grapevines occurs as soon as they begin to grow in spring, but epidemics seem to stall for about six weeks and go nowhere fast. We've found that it's our cold nights that are suppressing the disease. Two modes of action are suggested. First, cold nights stimulate a temporary defense response in the youngest, and ordinarily most-susceptible, leaves. Second, cold causes direct damage to the mildew colonies.
The National GAPs (Good Agricultural Practices) Program has developed a multifaceted approach to encourage and assist growers, packers, and farm workers with the implementation of good agricultural practices to reduce microbial risks in fresh fruits and vegetables. This program combines research, education, and extension to create dynamic educational materials including books, video, photo novels, coloring books, posters, websites, online courses, high school agriculture curricula, and magnets for the many diverse audiences that have an interest in produce food safety.
This project was developed to increase marketing opportunities for small businesses that depend on recreational fishing activities on Long Island. The project creates opportunities for partnerships between businesses that are based in different sectors but share a common market.
The respiratory chain in the mitochondrial inner membrane is the "machine" that captures energy for the cell when food is oxidized. It is built from proteins encoded in both the nucleus and a small chromosome inside mitochondria. We are trying to understand the mechanisms that control mitochondrial gene expression and target its protein products to the assembly of the respiratory chain.
The Apple Physiology and Culture program at Cornell has developed over the past 20 years an integrated crop physiology approach with field experimentation and dynamic crop modeling that has substantially improved the understanding of the complex behavior of apple orchards in the variable environment. Outputs from the model are providing critical real-time quantitative information helping growers optimize their orchard management, especially control of the yield, for better profitability.
The primary focus of this project is to support the existing and expanding grape and wine industries in New York and other states east of the Rocky Mountains by increasing the abilities of grape producers and their advisers to manage infectious diseases that limit profitability and preclude sustainable production if not addressed adequately. Additionally, the project has several components that are applicable to the grape industry in the western U.S. and to those in overseas locations.
