The interaction between carbon and nitrogen dominates the primary metabolism in plants, and therefore elucidating this interaction is critical for understanding the physiology of the whole plant. We are currently focused on how nitrogen supply affects carbon metabolism and nitrogen metabolism in both apples and grapes. Pome and stone fruits of the Rosaceae family, such as apple and cherry, are unique in that sorbitol serves as a primary end-product of photosynthesis and a major translocated carbohydrate in the phloem. Sorbitol is also implicated in responses to environmental stresses. We are using apple trees with decreased sorbitol synthesis to understand the role sorbitol plays in carbohydrate metabolism, organic acid metabolism and nitrogen metabolism, and stress tolerance. We are very interested in both primary metabolism and secondary metabolism relevant to fruit quality during fruit growth and development as well as their responses to nutrient stress and other environmental stresses. Sugar/acid accumulation and metabolism in apple fruit is one of the foci of our current work. On the more applied side, our research addresses uptake, translocation, storage, and remobilization and demand-supply relationship of nitrogen and other nutrients in apples and grapevines to provide basis for optimizing nutrient inputs into both apple orchards and vineyards
