Ammonia movements in rhizobia
When free-living rhizobia are grown under N-excess conditions they appear to take up ammonia by a diffusive mechanism. Under low or limiting N, they derepress an ammonium permease which serves to scavenge NH4+. Current data suggest that N2-fixing bacteroids lose ammonia by a diffusive movement sustained by the continual removal of ammonia via the plant ammonia assimilatory system(s).
