Abstract

A group of four diverse rhizobial isolates and two soil isolates that are highly related to were characterized by a polyphasic approach. On the basis of DNA–DNA hybridizations and phenotypic features, these strains cannot be distinguished clearly form , a soil bacterium that was described in 1982, mainly on the basis of phenotypic characteristics. Phylogenetically, and form a single group in the 16S rDNA dendrogram of the -, as well as in an analysis of partial gene sequences. They may therefore be regarded as a single genus. Because was proposed in 1988, according to the (1990 Revision) the older name, , has priority. However, there are several reasons why a change from to may not be the best solution and making an exception to Rule 38 may be more appropriate. We therefore propose the species comb. nov. and put forward a Request for an Opinion to the Judicial Commission regarding the conservation of over .
