Argentina: Genetic blueprint of potatoes revealed

An international group of researchers from fourteen countries, including INTA specialists, unravelled the sequence of the potato genome, which will make it possible to identify the genes responsible for quality and performance.

Almost 40,000 genes were identified and classified in a genetic map. Sergio Feingold, director of INTA's Agro-biotechnology Laboratory considered the achievement "a great discovery" which opens the possibility to identify genes of particular agronomic, nutritional and industrial interest to incorporate them to improvement programs.

Scientists managed to integrate the potato genome with other genetic and physical maps, as well as that of other crops, such as tomatoes, also recently published.

From these findings, specialists will be able to re-interpret the discoveries made over the past 30 years connecting DNA regions to potato characteristics of interest, and identify the genes responsible for these associations, contributing to the improvement of performance and sanitary characteristics, as well as nutritional and industrial production aspects.
