Characterization of the complete mitochondrial genome ofyamaguti, 1935 (Palaeacanthocephala: Echinorhynchida) in cultured large yellow croaker () and its phylogenetic implications.

Abstract

A species of acanthocephalan collected from the hindgut ofwas identified asYamaguti, 1935 based on morphological characteristics. The complete mitochondrial genome of this parasite was sequenced. The mitogenome exhibited a circular structure with a total length of 14 632 bp, containing 12 protein coding genes (PCGs), 2 ribosomal RNAs (rRNAs), 22 transfer RNAs (tRNAs) and 2 major non-coding regions. The most frequently used start codon was GTG, and the most abundant amino acid was valine. The phylogenetic analyses of the mitogenome using Bayesian inference and maximum likelihood methods showed that the genusformed a sister clade to the genus, supporting the monophyly of. This study reported a new host forand revealed the first complete mitogenome sequence of the genus.
