Research Project: Characterization of Mechanisms Regulating Nutritional Content and Quality of Specialty and Processing Potatoes

Location: Temperate Tree Fruit and Vegetable Research

Project Number: 2092-21220-001-04-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Jun 29, 2011
End Date: May 31, 2016

This collaboration will assess phytonutrient levels in diverse potato germplasm and characterize mechanisms and factors that control phytonutrient content or processing quality.

Potato can be made even more nutritious by developing varieties that have higher levels of antioxidants such as phenolics, vitamin C, anthocyanins and carotenoids. A better understanding of the mechanisms that influence the amounts of phytonutrients in tubers, including both in planta and external environmental influences including post-harvest factors or crop management will facilitate development of high-phytonutrient potatoes. A combination of physiological, biochemical and molecular techniques, including metabolic profiling, gene expression, metabolic engineering and enzyme analysis will be used to address these factors.
