The complete mitogenome of the springtail Tullbergia bisetosa: a subterranean springtail from the sub-Antarctic region.

Tullbergia bisetosa is a springtail (Collembola) native to the sub-Antarctic Prince Edward Islands. Unlike most other springtails, it has acquired a euedaphic (living within the soil) life form. In the present study, the complete mitogenome of T. bisetosa was sequenced. It has a length of 15,204 bp and comprises 13 protein-coding genes, 22 tRNAs, and two rRNAs. The mitogenome has the following base composition: A = 35.5%, T = 32.3%, G = 10.6%, and C = 21.1%. A Bayesian phylogenetic tree shows that T. bisetosa is grouped with springtails that possess similar morphological features and similar life histories. Our results suggest a mitogenomic signal towards morphological traits that conforms to a euedaphic lifestyle. [ABSTRACT FROM AUTHOR]
