The complete mitochondrial genome of the Antarctic fairy shrimp Branchinecta gaini Daday, 1910 (Branchiopoda, Anostraca, Branchinectidae)

Abstract

The complete mitochondrial genome of Antarctic fairy shrimp Branchinecta gaini Daday, 1910 was sequenced, assembled and annotated using next-generation sequencing technology. The mitogenome of B. gaini is circular at 15,536 bp in length, consisting of 13 protein-coding genes, 23 tRNAs, two rRNAs and two major non-coding regions. In particular, there are two tRNAGly genes and one non-coding region between these two tRNAGly genes. A phylogenetic tree was constructed using concatenated amino acid sequences of 13 protein-coding genes. It reveals that B. gaini is clustered with the Anostraca group within the Branchiopoda clade. This study helps us understand the evolution of Anostraca.
