Complete genome sequence of Nibribacter radioresistens DG15C, a radiation resistant bacterium

Backgrounds: The ionizing radiation from the gamma rays is damaging the genetic materials of the cells, possibly leading to cell death and cause permanent changes within daughter cells. A red pigmented, Gramnegative, aerobic, short-rod shaped, non-motile, UV and gamma radiation tolerant bacterium Nibribacter radioresistens DG15C was isolated from a soil sample collected in a rice field in South Korea. Methods: The complete genome of DG15C was sequenced and assembled using Pacific Biosciences RS II system. The genome sequence was annotated using Genomes-Expert Review (IMG-ER) platform, Prodigal, and JGI GenePRIMP pipeline. The protein-coding genes were identified using Prodigal, Pfam and COG databases implemented in the IMG systems. Results: The complete genome sequence of strain DG15C consists of a circular chromosome (4,143,738 bp) encoding 3,969 coding sequences (CDs) and 3,582 genes. The bacterium showed resistance to gamma and UVC radiations. Conclusion: The genome annotation as confirmed the presence of gene clusters involved in the toxicity resistance of radiation.
