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

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.

Autoregulation dependent and independent mechanisms are responsible for the systemic control of nodule formation by the plant N demand

This study identifies both autoregulation-dependent and -independent mechanisms controlling systemic N signaling in nodule formation in legumes.

Rhizobium leguminosarum symbiovar viciae strains are natural wheat endophytes and can stimulate root development and colonization by arbuscular mycorrhizal fungi

The paper identifies Rhizobium leguminosarum symbiovar viciae strains that can colonize wheat roots and promote root development and arbuscular mycorrhizal fungal colonization.
