Rhizobium leguminosarum

Rhizobium leguminosarum is a nitrogen-fixing plant symbiont. We have sequenced biovar viciae strain 3841, a spontaneous streptomycin-resistant mutant of strain 300. Further information on the organism and strain is on our collaborators' website.

The Sanger Institute was funded by the BBSRC to sequence the genome of Rhizobium leguminosarum, in collaboration with Prof. Peter Young of the Department of Biology, University of York , and Prof. Andy Johnston of the Department of Biological Sciences, University of East Anglia.

Published Genome Data

The finished genome consists of a circular chromosome of 5,047,142 bp, and six plasmids; pRL12 (870,021 bp), pRL11 (684,202 bp), pRL10 (488,135 bp), pRL9 (352,782 bp), and pRL8 (147,463 bp). The total size is 7,751,309 bp and the averge G+C content is 60.86 %.

The fully annotated chromosome is available in the EMBL/GenBank databases with accession number AM236080. The plasmids are similarly available with accession numbers AM236081, AM236082, AM236083, AM236084, AM236085 and AM236086.

Shotgun and assembly data from this project are available from our FTP site.


  • The genome of Rhizobium leguminosarum has recognizable core and accessory components.

Data Use Statement

This sequencing centre plans on publishing the completed and annotated sequences in a peer-reviewed journal as soon as possible. Permission of the principal investigator should be obtained before publishing analyses of the sequence/open reading frames/genes on a chromosome or genome scale. See our data sharing policy.
