Abstract
The two complete mitochondrial genomes were sequenced from the monogonont rotifer Brachionus rotundiformis. The genome sequences were 10,268 bp and 11,703 bp in size, and the gene order and contents were identical with those of B. koreanus but were different in tRNA-Cys with B. plicatilis mitochondrial genomes. Of the 12 protein-coding genes (PCGs), five genes (ND1, ATP6, ND5, CO3, ND3) had incomplete stop codons. Furthermore, the start codon of ND4 and CO3 gene was ATA, while the start codon of other PCGs was ATG. The base composition of B. rotundiformis mitogenome shows an anti-G bias (12.05% and 10.24%) on the second and third position of the PCGs, respectively.
Highlights
KEYWORDS Brachionus rotundiformis; complete mitochondrial genome; Monogonont rotifer
More than 30 species are described in the genus Brachionus
To date, only a few complete mitochondrial genomes have been published in the genus Brachionus sp. (Suga et al 2008 for B. plicatilis; Hwang et al 2014 for B. koreanus)
Summary
KEYWORDS Brachionus rotundiformis; complete mitochondrial genome; Monogonont rotifer More than 30 species are described in the genus Brachionus (https://en.wikipedia.org/wiki/Brachionus). 15 species were deciphered for their phylogenetic placement through DNA taxonomy using CO1 and ITS1 genes in the Brachionus plicatilis species complex (Mills et al 2016).
