Nitrogen (N) as well as Phosphorus (P) are key nutrients determining crop productivity.
Legumes have developed strategies to overcome nutrient limitation by, for example, forming
a symbiotic relationship with N-fixing rhizobia and the release of P-mobilizing exudates and
are thus able to grow without supply of N or P fertilizers. The legume-rhizobial symbiosis
starts with root release of isoflavonoids that act as signaling molecules perceived by
compatible bacteria. Subsequently, bacteria release nod factors, which induce signaling …

Rhizobium-Fabaceae symbiotic interaction …
