ABSTRACT
|
|---|
In conformity with the nomenclature of the genus Rhizobium published by Young et al. (Int J Syst Evol Microbiol 51, 89–103, 2001
), it is proposed that Agrobacterium larrymoorei be named as Rhizobium larrymoorei comb. nov.

A gall-forming pathogen from Ficus benjamina (Bouzar et al., 1995) was subsequently characterized and named Agrobacterium larrymoorei (Bouzar & Jones, 2001). Comparative analysis of 16S rDNA sequences gives an inferred phylogeny of this species as being closely related to other agrobacteria on a larger clade comprising known Rhizobium species (Bouzar & Jones, 2001) and other Agrobacterium species (Young et al., 2001). Following their analysis of available data, Young et al. (2001) proposed that species in Agrobacterium were members of an artificial genus established only on pathogenicity characters that were carried on transferable plasmid-borne genes. Because there are no other data to support the differentiation of Agrobacterium as a distinct genus, Young et al. (2001) proposed that all Agrobacterium species were more properly considered to be members of Rhizobium. This is also true for Agrobacterium larrymoorei. Following Rule 34a of the International Code of Nomenclature of Bacteria (Prokaryotes) (Lapage et al., 1992), it is proposed that the epithet larrymoorei be applied to this species as a new combination in Rhizobium. Those who wish to use a nomenclature that reflects natural and polyphasic relationships as presently understood may prefer this nomenclature to the special-purpose use of Agrobacterium. The alternative name Rhizobium larrymoorei is proposed for this species.
