Nod factors are recognized by the Nod factor receptor (NFR) in legumes, Upon binding to Nod factors, the NFR heterodimer initiates two main separate processes mediated by SYMRK such as;

a) A signaling pathway that facilitates the infection process itself

b) Activation of the symbiosis receptor-like kinase (SYMRK)

c) Activating an extracellular domain that includes a leucine rich repeat (LRR) region and an intracellular protein kinase domain

d) The activation of a set of genes that regulate the formation of root nodules
