Abstract
Rhizobia are the bacteria that form nitrogen-fixing symbioses with legumes. Based on their characterisation by polyphasic taxonomy, their classification has undergone great changes in recent years. The current six rhizobium genera and 28 recognised species are reviewed here.

Résumé
Taxonomie des rhizobia. Les rhizobia sont les bactéries qui forment des symbioses fixatrices d'azote avec des plantes de la famille des légumineuses. Suite à l'adoption de la taxonomie polyphasique comme critère de caractérisation, leur classification a subi de nombreux remaniements ces dernières années. Une revue de cette classification en six genres et 28 espèces actuellement reconnus est présentée ici.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
