The complete mitochondrial genome of Heterakis dispar (Ascaridida: Heterakidae)

Abstract

The complete mitochondrial genome sequences of Heterakis dispar were determined for the first time in present study. The lengths of mtDNA sequences of H. dispar is 13,995 bp in size, containing 12 PCGs (cox1-3, nad1-6, nad4L, atp6, and cytb), two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and two non-coding regions, all genes are encoded by the same strand. The phylogenetic analysis by Bayesian inference method revealed that Ascaridiidae was closely related with Heterakidae than to other Ascaridida nematodes. In Heterakidae, H. dispar was closely related with H. gallinarum than to H. beramporia with high statistical support. The mtDNA dataset provided useful genetic markers for studying the molecular ecology, systematics, and population genetics of Ascaridida nematodes.
