Potato Proteomics: A New Approach for the Potato Processing Industry

Abstract Potato, as the world’s most important nongrain food crop, is a star on the global market. It is valued for its nutritional qualities for human and animal consumption and is the main source of starch for the food industry. Its complete genome sequencing in 2011 opened the way for detailed proteomic analysis of this major crop. The relevance of high-throughput proteomic approaches is to increase insight and understanding of how the intimate mechanisms that exist at the subcellular level can influence potato quality thus enabling the optimization of the overall food production process. In this review, we outline the state-of-the-art of proteomic advances in potato research and their applications to its nutritional qualities, stress and pest resistance, transgenic crops, response to fertilization, and cooking and outline several possible future proteomic approaches that could lead to better quality produce, extended shelf life, and the optimization of isolation of molecules of interest.
