Ammonia movements in rhizobia.
Microbiological sciences, 1990When 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

Canadian Journal of Microbiology, 1992
Extensive cross testing on a relatively few legume hosts led initially to a taxonomic characterization of rhizobia based on bacteria–plant cross–inoculation groups. This has gradually become less acceptable, and has been replaced by taxonomic groupings derived from numerical taxonomy, carbohydrate metabolism, antibiotic susceptiblities, serology, and ...

Functional Genomics of Rhizobia
2007Complete genome sequences of a number of rhizobia have recently become available and constitute an archive of data which paved the way for postgenomic strategies. This review summarizes data deduced from the genome sequences of rhizobia and related bacteria.

The host-rhizobia relationship
1999Conserving and experimenting with the genetic resources of legumes are almost worthless pursuits if similar attention is not given to their microsymbiotic partners. The nitrogen fixing symbiosis between members of the Leguminosae and the four separate but related bacterial genera Rhizobium, Bradyrhizobium, Azorhizobium and Sinorhizobium is a ...
