We welcome Dr. Jessy Labbé, a former INRA Ph.D. student, who joins us from the Biosciences Division at Oak Ridge National Laboratory (TE, USA). Within the framework of the DOE Plant-Microbe Interfaces project, Jessy is working with François Le Tacon and Francis Martin on the QTL for mycorrhiza formation in poplar. He is funded by the LabeX ARBRE.
