By the symbiotic nitrogen fixation process, bacteria of the family Rhizobiaceae convert atmospheric dinitrogen (N2) to ammonia (NH3), which can be effectively utilized by host legume plants. Symbiotic nitrogen fixation contributes significantly to global nitrogen cycles and agricultural practice. The establishment of rhizobia-legume symbiosis requires the induction of new developmental programs in respective partners. The symbiotic interaction begins with signal exchanges of flavonoids and bacterial nodulation signals, Nod factors, between the two partners (Denarie et al 1996). However, the establishment of nitrogen-fixing symbiosis probably requires more complex steps triggered by reciprocal signal exchanges leading to the organogenesis of nodules and differentiation of the microsymbionts (Niner and Hirsch 1998).
