Complete genome sequence of ionizing radiation-resistant Hymenobacter sp. strain PAMC26628 isolated from an Arctic lichen

•The genome of ionizing radiation-resistant Hymenobacter sp. strain PAMC26628 was sequenced.•It consists of an 5.2Mb chromosome and one plasmid (89,596bp).•Genes predicted involved in nucleotide excision repair and a DNA damage removal pathway were analyzed. Ionizing radiation-resistant Hymenobacter sp. strain PAMC26628 was isolated from Stereocaulon sp., an Arctic lichen. Complete genome sequencing of Hymenobacter sp. PAMC26628 revealed one chromosome (5,277,381bp), one plasmid (89,596bp), and several genes involved in nucleotide excision repair, a DNA damage removal pathway. An analysis of the Hymenobacter sp. PAMC26628 genome will help us understand its evolution and provide novel insight into the adaptations that allow this organism to survive in the extreme cold of the Arctic.
