Symbiotic nitrogen-fixing rhizobia release nodulation (Nod) factors as signaling agents as they near the surface of a legume root. The interaction between specific nod factors and their corresponding receptors. Which of the following statements is incorrect?

#Botany
  1. Nod factors are lipochitin oligosaccharides that bind to a specific class of receptor-like kinases (RLKs) in a species-specific manner
  2. The receptor has two heterodimer, Nod factor receptor 1 and 5 (NFR1 and NFR5). Both have three extracellular LysM domains
  3. Nod factor receptors (NFRs) contain extracellular LysM motifs, initiates an interaction with the conserved SYMRK receptor-like kinases containing a leucine-rich repeat (LRR) domain
  4. The interaction between NFR and SYMRK initiates calcium spiking in the cytosol, presumably via a second messenger molecule
