Complete mitochondrial genome of the freshwater monogonont rotifer Brachionus angularis (Rotifera, Brachionidae)

Abstract

The two complete mitochondrial genomes were sequenced from the freshwater monogonont rotifer Brachionus angularis. The mitochondrial genome sequences were 10,764 bp (mitochondrial DNA I) and 12,238 bp (mitochondrial DNA II) in size, respectively. Of 12 protein-coding genes (PCGs), one gene (ND5) had incomplete stop codon. Furthermore, the start codon for CO1, ND4L, ND5, and CO2 was GTG, while the start codon for ND3 was ATA, respectively, whereas the start codon for other PCGs was ATG. The base composition of 12 PCGs in B. angularis mitogenome showed 20.4% for A, 47.3% for T, 17.5% for C, and 14.8% for G, respectively. The mitochondrial genome A+T base composition (67.7%) of 12 PCGs was higher than G+C (32.3%), while the complete mitochondrial genome A+T base composition (66.3%) was higher than G+C (33.7%)
