Legumes form symbiosis with rhizobia, which fix nitrogen for the benefit of host plant in return for carbon resources. Development of this unique symbiosis in legumes is triggered by rhizobia-secreted nodulation (Nod) factors (NFs). NFs, upon perception, activate Nod signaling cascade, leading to reprogramming of host cell (root) developmental networks to pave way for accommodating rhizobial symbionts
