The complete mitochondrial DNA sequence of Heterochaerus australis (Acoela, Convolutidae)

Abstract

One complete mitochondrial genomes (mitogenomes) was determined for Heterochaerus australis (Acoela, Convolutidae). Its mitochondrial genome size was 13,885 bp. The sequence contains 2 ribosomal RNA genes (rrnL and rrnS), 20 tRNA genes, and 12 protein-coding genes (PCGs). The A + T content of the complete mitochondrial genome sequence was 70.8%. The base composition showed a tendency of high AT. The resulted maximum likelihood (ML) tree supported that Acoela had a distant relationship with other orders of Turbellaria and the Xenacoelomorpha.
