Nitrate reductase activity is required in Medicago truncatula-Sinorhizobium meliloti nitrogen-fixing symbiosis

Marc Bosseno, Demba Alexandre, Natasha Horta Araújo, Dominique Colinet, Marie Pacoud, Yassine El Fazaa, Marc Lepetit, Gilles Clément, Renaud Brouquisse, Alexandre Boscari

This study shows that nitrate reductase activity is essential for the nitrogen-fixing symbiosis between Medicago truncatula and Sinorhizobium meliloti, as evidenced by impaired nodulation in a double mutant.
