This site is devoted to different issues related to the molecular systematics, taxonomy, genomics, ecology and evolution of symbiotic legume nodule bacteria, which are collectively known as "RHIZOBIA". It's mission is to provide a useful resource to the community of rhizobiologists/agrobacteriologists. Besides up-to-date links to all validly described rhizobial/agrobacterial taxa, the site provides hands-on tutorials on different issues in phylogenetic analysis of sequence data and lots of other valuable information such as links to forthcoming scientific meetings, key papers in the above mentioned areas, etc. Your contributions to enrich this site are welcome!

Taxonomic recommendations are posted now

A few general guidelines on good taxonomic and systematic practice have been posted on September 30th 2007. A major update of the site was also performed.

Welcome to the official web site of the "ICSP - Subcommittee on the taxonomy of Rhizobium and Agrobacterium"

Bean nodules elicited by Rhizobium tropici CIAT899 expressing a gfp-fusion

On this site you will find:

1) Up-to-date taxonomic information about all validly published and forthcoming rhizobial/agrobacterial taxa.

2) Hands-on tutorials on how to perform rigorous phylogenetic analyses using sequence data, from SSU rRNA sequence alignment and model fitting, up to ML tree searches.
