The complete mitochondrial genome of Ictidomys tridecemlineatus (Rodentia: Sciuridae)

The complete mitochondrial genome of the thirteen-lined ground squirrel, Ictidomys tridecemlineatus (Rodentia: Sciuridae) was sequenced to analyze the gene arrangement. It is a circular molecule of 16,458 bp in length including 37 genes typically found in other squirrels. The AT content of the overall base composition is 63.7% and the length of the control region is 1016 bp with 63.0% AT content. In BI and ML phylogenetic trees, I. tridecemlineatus is a sister clade to the genus Cynomys, and Tamias sibiricus is a sister clade to (Marmota himalayana + (I. tridecemlineatus + (C. leucurus + C. ludovicianus))). Ratufinae is well supported as the basal clade of Sciuridae. The monophyly of the family Sciuridae and its subfamilies Callosciurinae, Xerinae and Sciurinae are well supported
