The topic of nutrient density in food crops has been active among consumers, producers and the scientific community in recent years. Literature on food composition demonstrates that the mineral nutrient density of vegetables has fallen in the past 50 years. This decline is associated with two factors: declines in soil fertility and with the genetics of plant cultivars that accumulate yield at higher rates than they accumulate mineral nutrients.
Improving management of cucurbit diseases, especially cucurbit downy mildew (CDM), has been consistently identified by growers and processors in MA as a major research priority in the past ten years. In 2004, new strains of CDM arrived which had overcome resistance that was then standard in all cucumber varieties and adequately controlled the disease.
Utilizing food systems to improve nutrition without the need for artificial fortification of food or use of dietary supplements of mineral nutrients is important in ending malnutrition. Malnutrition from deficiencies of mineral elements is reported to be on the rise worldwide, even in the United States. It is estimated that half of the world population suffers from incidences of mineral nutrient deficiencies. These deficiencies limit the physical, intellectual, and mental health activities of the affected people.

In order to compete in the marketplace, assure profitability and preserve the environment, cranberry growers must overcome barriers to sustainability. This project has three components related to increased sustainability in Massachusetts cranberry production:
Massachusetts Agricultural Experiment Station Project MAS00999
Duration: October 2010 - August 2015
Our current ignorance of most of the mechanisms involved in plant iron homeostasis is a major obstacle in devising approaches for biofortification of staple foods with iron. Biofortification refers to the genetic engineering of staple crops to accumulate additional bioavailable iron in edible parts, and is widely regarded as a sustainable means of improving the iron nutrition of the 2-3 billion people worldwide (World Health Organization) whose inadequate diet causes iron deficiency anemia.
During estrus, mares can behave in a manner that can make handling, riding, training, or competing these horses difficult. Current methods to suppress estrus behavior during the breeding season, when most horse competition takes place, include: pharmacological treatments; glass marbles; and negative reinforcement. This work will develpe strategies to control estrus behaviour without the need for pharmacological treatments or negative reinforcement.
Laminitis is a crippling disease that affects about one-percent of the more than nine million horses in North America. The cost of laminitis to the horse industry exceeds $1 billion annually, predominantly from loss of use of the affected animals rather than medical costs. Laminitis results from failure of the digital laminae, which suspend a horse's distal phalanx, and thus the axial skeleton and all that is attached to it, within the hoof capsule. The laminae are composed of a hoof wall-associated epidermal layer and a distal phalanx-associated dermal layer.
Plant diseases cause crop loss, reduce food production and threaten global food security (Savary et al., 2012). Focusing on two distinct pathosystems that cause Fusarium vascular wilts and the Basil downy mildew (BDM), respectively, we proposal to establish a pipeline to dissect host-pathogen interactions and provide novel means to develop disease resistant cultivars in order to manage plant diseases that threaten food security. Fusarium oxysporum species complex can cause vascular wilt on over 100 cultivated plant species (Beckman 1987, Moore et al.
