Draft genome sequence of a Sphingomonas sp., an endosymbiotic bacterium isolated from an arctic lichen Umbilicaria sp.

Sphingomonas sp. strain PAMC 26617 has been isolated from an Arctic lichen Umbilicaria sp. on the Svalbard Islands. Here we present the draft genome sequence of this strain, which represents a valuable resource for understanding the symbiotic mechanisms between endosymbiotic bacteria and lichens surviving in extreme environments.
