was isolated as a gram-negative, red-pigmented, radioresistant, rod-shaped bacterium from freshwater fish. The draft genome sequence of ATCC 43672 was 4,092,497 bp, with an average G+C content of 67.5% and comprised of 4 circular contigs and 3 linear contigs that was deposited at DDBJ/EMBL/Genbank under the accession number BCMS00000000. The draft genome sequence indicates that possesses a DNA damage response regulator (encoded by homolog) and radiation-desiccation response regulons (, , , and homologs etc.), which are involved in the unique radiation-desiccation response system in . As it is for , seems to employ the same radioresistant mechanisms. In future, the draft genome sequence of will be useful for elucidating the common principles of the radioresistance based on the extremely efficient DNA repair mechanisms in Deinococcus species by the comparative analysis of genomic sequences.
