Sequence and phylogenetic analysis of the mitochondrial genome for a giant clam commensal shrimp Anchistus australis (Decapoda: Caridea: Palaemonidae)

Abstract

The shrimp Anchistus australis was a giant clam commensal species. Here, we explored in detail its mitochondrial (mt) genome, which was 15,396 bp in length, containing 13 protein-coding genes, 2 ribosomal RNA genes, 21 transfer RNA genes, and a non-coding control region 429 bp in length. The overall mt genome organization of A. australis displayed the typical characters for the pancrustacean ground pattern, with exception of translocation of trnW and trnL1, as well as deletion of trnL2. Phylogenetic analysis confirmed its evolutionary relatedness to other shrimp of family Palaemonidae within Infraorder Caridea.
