PII and GlnK Control Ammonia Assimilation and Nitrogen Fixation in Azorhizobium Caulinodans
Azorhizobium caulinodans fixes nitrogen both in the free-living state (Nif+) and in symbiosis (Fix+) with its host plant, Sesbania rostrata (Elmerich, et al., 1982). In the free-living state, all the fixed nitrogen is assimilated through the glutamine synthetase enzyme (GS) for the bacteria growth, suggesting a coordination between ammonia assimilation and nitrogen fixation.
