Laboratory of seed biology INRA / AgroParisTechThe laboratory of seed biology “INRA / AgroParisTech”AgroParisTech has been created in 2007 by the merger of three high engineers schools of the Paris Region (INA P-G, ENREF, ENSIA). With 2000 students, 500 PhD-Students, 200 associated professors and 300 researchers divided about thirty research units covering a wide spectrum of topics, AgroParisTech is the biggest European school in the field of life sciences and technology. The AgroParisTech research unit of “Plant Physiology” is associated with an INRA unit, the laboratory of seed biology (UMR 204 INRA / AgroParisTech). Current research activities in the laboratory of seed biology “INRA / AgroParisTech” are divided into four main topics:
Through a large number of high quality publications the laboratory of seed biology “INRA / AgroParisTech” currently enjoyed an international appreciation. This lab is a very active and dynamic structure in the seed biology investigation. The laboratory of seed biology “INRA / AgroParisTech” takes advantage of a double localization. One site is located in the INRA-Versailles Research Centre inside the Jean-Pierre Bourgin Institut (IJPB). The other site is located in AgroParisTech premises in the heart of Paris where proteomic activities mainly take place.
