The binding of Nod factors to the Nod factor receptors (NFRs), which contain extracellular LysM motifs, initiates an interaction with the conserved SYMRK receptor-like kinases containing a leucine-rich repeat (LRR) domain.

The interaction between NFR and SYMRK initiates calcium spiking in the nucleus, presumably via a second messenger molecule.
Core symbiotic genes are activated.
Cytokinin signaling is initiated.

Three factors are important in maintaining low O2 concentrations in nodules. 
First, entry of O2 into the nodule is controlled by a variable‐permeability barrier in the nodule parenchyma
