Description Mitochondrial genomes are valuable for making inferences regarding population
genetics, phylogenetics and recently in understanding adaptive variation in
OXPHOS genes. Ribbon fish, Trichiurus lepturus is distributed in the Indian Ocean
and contributes to a major share of pelagic fish landings. Considering the importance,
we characterized the complete mitogenome of large head hairtail T. lepturus
from Indian waters by PCR amplification and sequencing. The entire mitogenome is
16,840 bp in length, with 13 protein coding genes, 2 subunit ribosomal RNA genes,
and 1 control region similar to other vertebrates. Genome contains only 21 tRNAs
(
tRNAPro is absent) as against 22 tRNAs reported in other vertebrates. The putative
origin of L-strand replication (
OL) was located in a cluster of five tRNA genes
(WANCY region) and may not be functional due to the variation of conserved motif
(5′-GCCGG-3′) and loop. These two unusual features are common for Trichiurus
mitogenomes. Phylogenetic analysis supported the monophyly of Trichiuridae. This
study will provide information for further studies on taxonomy, phylogeny and patterns
of adaptive evolution in the mitogenome of Trichiurus species.
