Abstract
Rhizobium sullae strain WSM1592 is an aerobic, Gram-negative, non-spore-forming rod that was isolated from an effective nitrogen (N2) fixing root nodule formed on the short-lived perennial legume Hedysarum coronarium (also known as Sulla coronaria or Sulla). WSM1592 was isolated from a nodule recovered from H. coronarium roots located in Ottava, bordering Sassari, Sardinia in 1995. WSM1592 is highly effective at fixing nitrogen with H. coronarium, and is currently the commercial Sulla inoculant strain in Australia. Here we describe the features of R. sullae strain WSM1592, together with genome sequence information and its annotation. The 7,530,820 bp high-quality permanent draft genome is arranged into 118 scaffolds of 118 contigs containing 7.453 protein-coding genes and 73 RNA-only encoding genes. This rhizobial genome is sequenced as part of the DOE Joint Genome Institute 2010 Genomic Encyclopedia for Bacteria and Archaea-Root Nodule Bacteria (GEBA-RNB) project.Electronic supplementary materialThe online version of this article (doi:10.1186/s40793-015-0020-2) contains supplementary material, which is available to authorized users.

Rhizobium sullae WSM1592 was isolated from a root nodule of Hedysarum coronarium
Phylogenetic analysis revealed that WSM1592 is the most closely related to Hedysarum coronarium IS 123T, which was isolated from Hedysarum coronarium growing in Southern Spain
Summary
The accessibility and supply of nitrogen fertilizer is an ever-increasing challenge that world agriculture faces [1]. We present a preliminary description of the general features for Rhizobium sullae strain WSM1592 together with its genome sequence and annotation. Inoculation of H. spinosissimum, H. flexuosum and H. carnosum with WSM1592 results in mostly Nodbut always Fix- Genome project history This organism was selected for sequencing on the basis of its environmental and agricultural relevance to issues in global carbon cycling, alternative energy production, and biogeochemical importance, and is part of the Genomic Encyclopedia of Bacteria and Archaea, The Root Nodulating Bacteria chapter project at the U.S Department of Energy, Joint Genome Institute [17]. Evidence codes – IDA Inferred from Direct Assay; TAS Traceable Author Statement (i.e., a direct report exists in the literature); NAS Non-traceable Author Statement (i.e., not directly observed for the living, isolated sample, but based on a generally accepted property for the species, or anecdotal evidence) These evidence codes are from the Gene Ontology project [42].
