#XL - R Botany

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.

Plant genes expressed early, or in the absence of bacterial infection, are termed “early nodulins” or ENOD
