Project description:The complete mitochondrial genome of Sirembo imberbis was determined by the bioinformatic assembly of the next generation sequencing (NGS) reads. Total length of the mitogenome was 16,717 bp, which harbors the conserved 13 protein-coding genes (PCGs), 2 ribosomal RNAs (12S and 16S), 22 tRNAs, and two non-coding region (the control region and the origin of light-strand replication). Among 13 protein-coding genes, unusual start codon (GTG) was exclusively identified in COX1, while the incomplete stop codons (TA- or T-) were detected in COX2, COX3, ND2, ND3, ND4 and CytB. As a result of phylogenetic tree, S. imberbis formed a cluster of the family Ophidiidae together with Bassozetus zenkevitchi and Lamprogrammus niger.
