Agrobacterium radiobacter is the only known non-phytopathogenic species in Agrobacterium genus. In this study, the whole-genome sequence of A. radiobacter type strain DSM 30147T was described and compared to the other available Agrobacterium genomes. This bacterium has a genome size of 7,122,065 bp distributed in 612 contigs, including 6,834 protein-coding genes and 41 RNA genes. It harbors a circular chromosome and a linear chromosome but not a tumor-inducing (Ti) plasmid. To the best of our knowledge, this is the first report of a genome from the A. radiobacter species. In addition, an emended description of A. radiobacter is described. This study reveals information that enhances the current understand-ing of its non-phytopathogenicity and its phylogenetic position within Agrobacterium genus.
