Journal Article
Complete mitochondrial genome of critically endangered catfish Hemibagrus punctatus (Jerdon, 1849) and comparative analysis for insights into the phylogeny of hemibagrids through mitogenomic approach
2024
Overview
Background
Hemibagrus punctatus
(Jerdon, 1849) is a critically endangered bagrid catfish endemic to the Western Ghats of India, whose population is declining due to anthropogenic activities. The current study aims to compare the mitogenome of
H. punctatus
with that of other Bagrid catfishes and provide insights into their evolutionary relationships.
Methods and Results
Samples were collected from Hemmige Karnataka, India. In the present study, the mitogenome of
H
.
punctatus
was successfully assembled, and its phylogenetic relationships with other
Bagridae
species were studied. The total genomic DNA of samples was extracted following the phenol–chloroform isoamyl alcohol method. Samples were sequenced, and the Illumina paired-end reads were assembled to a contig length of 16,517 bp. The mitochondrial genome was annotated using MitoFish and MitoAnnotator (Iwasaki et al
.,
2013). A robust phylogenetic analysis employing NJ (Maximum composite likelihood) and ASAP methods supports the classification of
H. punctatus
within the Bagridae family, which validates the taxonomic status of this species. In conclusion, this research enriches our understanding of
H. punctatus
mitogenome, shedding light on its evolutionary dynamics within the
Bagridae
family and contributing to the broader knowledge of mitochondrial genes in the context of evolutionary biology.
Conclusions
The study’s findings contribute to a better understanding of the mitogenome of
H
.
punctatus
and provide insights into the evolutionary relationships within other Hemibagrids.
