Manuel Rodríguez-Concepcion is an expert in isoprenoid metabolism. He and his group at the Center for Research in Agricultural Genomics (CRAG), in Barcelona, Spain, are using forward and reverse genetic as well as biochemical approaches in Arabidopsis to understand how plants regulate the metabolic flux through the MEP pathway and the cross-talk with downstream pathways for the production of isoprenoid end-products, with a main focus on carotenoids
