Abstract
Bradyrhizobium sp. WSM1253 is a novel N2-fixing bacterium isolated from a root nodule of the herbaceous annual legume Ornithopus compressus that was growing on the Greek Island of Sifnos. WSM1253 emerged as a strain of interest in an Australian program that was selecting inoculant quality bradyrhizobial strains for inoculation of Mediterranean species of lupins (Lupinus angustifolius, L. princei, L. atlanticus, L. pilosus). In this report we describe, for the first time, the genome sequence information and annotation of this legume microsymbiont. The 8,719,808 bp genome has a G + C content of 63.09 % with 71 contigs arranged into two scaffolds. The assembled genome contains 8,432 protein-coding genes, 66 RNA genes and a single rRNA operon. This improved-high-quality draft rhizobial genome is one of 20 sequenced through a DOE Joint Genome Institute 2010 Community Sequencing Project.Electronic supplementary materialThe online version of this article (doi:10.1186/s40793-015-0115-9) contains supplementary material, which is available to authorized users.
Highlights
Root nodule bacteria are soil microorganisms that can establish a symbiotic relationship with hosts from the legume plant family Leguminosae

Summary
In Australia, the challenge was to select inoculant strains that were optimal for N fixation in symbiosis with Lupinus angustifolius and several species of Ornithopus. Strain WSM1253 was isolated from a nodule of the herbaceous annual legume Ornithopus compressus in 1991 collected 2.5 km near of Kastro, towards Faros, on the Greek Island of Sifnos. This strain was found to be capable of high levels of nitrogen fixation across many species in the cross-nodulation complex of lupins and Ornithopus, being effective on L. princei [14].
