Abstract
The complete mitochondrial genome sequence of Brevimulticaecum sinensis was clarified in this study, and this is the first member of the genus Brevimulticaecum ever sequenced for complete mitochondrial genome. The circular mitochondrial genome (13887 bp) of B. sinensis encodes 12 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and 2 non-coding regions, all genes exhibiting a nucleotide composition bias toward AT. Phylogenetic studies showed that B. sinensis and Ortleppascaris sinensis formed a monophyletic group belonging to the family Heterocheilidae. The complete mitochondrial genome sequence of B. sinensis should enrich molecular markers for studying the molecular classification, genetic variation, and phylogenetic studies of the Ascaridida nematodes.
期刊介绍：
This open access journal publishes high-quality and concise research articles reporting the sequence of full mitochondrial genomes, and short communications focusing on the physical, chemical, and biochemical aspects of mtDNA and proteins involved in mtDNA metabolism and interactions.
