“…The palindromic motifs 'TACAT' and ' ATGTA' that tend to form hairpin loop structures were found dispersed in the control region in multiple copies. Such identical motifs have also been observed in domestic mithun and other closely related bovine species as well as in other vertebrates 18,19,35,36 , and these are believed to function as the termination site for the elongation of heavy strand 37 . The control region terminated with a characteristic poly-C stretch (13 nucleotides) which was also observed in domestic mithun 18 (Supplementary Information Table S3).…”

“…Also, notably, all the PCGs showed positive AT skew except for the genes cox1, cox3, and nad6, whereas GC skew was positive only in nad6 gene. As commonly observed in other bovine and vertebrate species 18,19,32,33 , the PCGs were subdivided into seven NADH dehydrogenase subunits (nad1, nad2, nad3, nad4, nad4L, nad5 and nad6), three cytochrome c oxidase (cox1, cox2 and cox3), two ATPase subunits (atp8 and atp6) and a cytochrome b gene (cob). The size of the PCGs varied significantly with atp8 (201 bp) being the shortest and nad5 (1821 bp) being the longest among all.…”

“…The size of the PCGs varied significantly with atp8 (201 bp) being the shortest and nad5 (1821 bp) being the longest among all. Besides, there were four adjacent pairs of PCGs (atp8-atp6, atp6-cox3, nad4L-nad4 and nad5-nad6) which is a common gene positioning observed among the vertebrates 18,19,33 . The relative synonymous codon usage (RSCU) analysis showed the highest utilization of CUA, GGA, GUA and CGA codons among PCGs (Fig.…”

“…Considering the above facts, genetic characterization of gaur holds great importance. Mitochondrial genome has been widely used to study the evolutionary and phylogenetic relationship of various species due to its high mutation rate and lack of recombination 16 – 19 . In the present study for the first time, we sequenced the complete mitochondrial genome of four Indian gaur sampled from different places of India.…”

the gaur is the largest extant cattle species and distributed across South and Southeast Asia. Around 85% of its current global population resides in India, however there has been a gradual decrease in the gaur population over the last two decades due to various anthropogenic activities. Mitochondrial genome is considered as an important tool for species identification and monitoring the populations of conservation concern and therefore it becomes an obligation to sequence the mitochondrial genome of Indian gaur. We report here for the first time 16,345 bp mitochondrial genome of four Indian gaur sequenced using two different approaches. Mitochondrial genome consisted of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a control region. Among the 37 genes, 28 were positioned on the H-strand and 9 were positioned on the L-strand. The overall base composition appeared to be 33.5% A, 27.2% T, 25.9% C and 13.4% G, which yielded a higher AT content. The phylogenetic analysis using complete mitochondrial genome sequences unambiguously suggested that gaur is the maternal ancestor of domestic mithun. Moreover, it also clearly distinguished the three sub species of B. gaurus i.e. B. gaurus gaurus, B. gaurus readei and B. gaurus hubbacki. Among the three sub species, B. gaurus gaurus was genetically closer to B. gaurus readei as compared to B. gaurus hubbacki. The findings of our study provide an insight into the genetic structure and evolutionary history of indian gaur. The gaur, Bos gaurus also known as "Indian bison" is the largest living wild cattle species belonging to the family Bovidae 1. The historical distribution of gaur ranged throughout much of the mainland South and Southeast Asia. But, currently it occurs in a few Asian countries such as Bangladesh,

“…Most genes of H. herbertaxelrodi mitochondria are encoded on the H-strand, and only ND6 and eight tRNA (Gln, Ala, Asn, Cys, Tyr, Ser, Glu, and Pro) genes are encoded on the L-strand. In the 13PCGs gene, except that the COI starts with GTG, the others use ATG as the start codon, which is very common in vertebrate mtDNA (Prabhu et al 2020). Most of the termination codon TAA or T-, only the stop codon COI for AGG.…”

In this study, the complete mitochondrial genome of Hyphessobrycon herbertaxelrodi is presented, and we also discussed its mitochondrial characteristics. The full length of the mitochondrial genome was 17,417 bp, including 13 protein coding genes (PCGs), 2 ribosomal RNAs (12S and 16S), 22 transfer RNA genes, 1 non-coding control region (D-loop), and 1 origin of replication on the light-strand. The total nucleotide composition of mitochondrial DNA was 29.76%A, 29.88%T, 25.35%C, 15.01%G, and AT was 59.64%. The phylogenetic tree suggested that H. herbertaxelrodi shared the most recent common ancestor with Astyanax giton, Grundulus bogotensis, Astyanax paranae, and Oligosarcus argenteus.
