Ammonia movements in rhizobia

Glenn, A.R. and Dilworth, M.J. (1985) Ammonia movements in rhizobia. Microbiological Sciences, 2 (6). 161-2, 165.


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).
