Characteristics of the complete mitochondrial genome of the monotypic genus Arctictis (Family: Viverridae) and its phylogenetic implications.

The binturong (Arctictis binturong) is classified as a member of the subfamily Paradoxurinae within the family Viverridae (Carnivora: Mammalia) and comprises nine subspecies spread across Southern and Southeast Asia. Here, we describe the complete mitochondrial genome of the Indian subspecies A. b. albifrons using next-generation sequencing methods. The total length of the A. b. albifrons mitogenome was 16,642 bp. Phylogenetic analyses based on 13 mitochondrial protein-coding genes placed the binturong as a sister taxon to Paguma larvata within the Paradoxurinae and supported the clustering of Genettinae and Viverrinae and the monophyly of Viverridae and six other families of feliforms, consistent with previous studies. Divergence time estimates suggest that the Viverridae diversified during the Miocene (22.62 Mya: 95% CI [20.78-24.54] Mya) and that Arctictis and Paguma split 12.57 Mya (95% CI [8.66-15.67] Mya). Further molecular studies are required to test the distinctiveness and diversity of the nine putative subspecies of binturong.

Characterization of the complete mitogenome of Indian Mouse Deer, Moschiola indica (Artiodactyla: Tragulidae) and its evolutionary significance.

The mitochondrial genome of Indian mouse deer (Moschiola indica) was sequenced, assembled and characterized for the first time using 22 pairs of polymerase chain reaction (PCR) primers. The mitogenome of M. indica which is 16,444 bp in size was found very similar to most vertebrates in organisation that harbours 13 protein-coding genes, 22 transfer RNA, 2 ribosomal RNA and 1A + T-rich region. Its comparison with over 52 mitogenomes of the order Artiodactyla, showed a conserved nature of gene organisation, codon usage, gene orientation and evolutionary rates of proteins except that M. indica possesses an extra copy of trnF. The complete mitogenome and protein-coding genes of M. indica were found to be highly A + T biased. Rate of protein evolution was highest in atp8 and lowest in cox3. Further, a higher purifying selection pressure was found to be acting on family Tragulidae compared to Bovidae and Cervidae. The phylogenetic analysis of M. indica placed the Tragulidae as sister-group of all other ruminants, similar to previous analyses. Moschiola forms the sister-group to the other two tragulid genera Tragulus (from Asia) and Hyemoschus (from Africa), which is unexpected as usually the Asian species are thought to form a monophyletic group.

The complete mitochondrial genome of Asian palm civet (Paradoxurus hermaphroditus) with phylogenetic consideration.

Asian palm civet (Paradoxurus hermaphroditus) is one of the smallest palm civet which is least studied. Here, we report the first complete mitochondrial (mt) genome of Asian palm civet (P. hermaphroditus). The circular mt genome with a length of 16,706 bp contained 1 control region, 2 rRNAs, 13 protein-coding genes, and 22 tRNAs. Overall base composition of the complete mt DNA was 33.7% A, 30.5% T, 22.9% C, and 12.9% G. All the genes in mt genome of Asian palm civet (P. hermaphroditus) were distributed on the H-strand, except ND6 and eight tRNA genes encoded on the L-strand. Maximum likelihood (ML) and Bayesian inference (BI) methods were used to infer the phylogenetic relationship of P. hermaphroditus. The phylogenetic analysis shows that all species from the family Viverridae cluster together, in which P. hermaphroditus exhibits the closest relationship with P. larvata.

Complete mitochondrial genome sequence of the Indian clouded leopard (Neofelis nebulosa).

The complete mitochondrial genome of sequence 16,859 bp of Indian clouded leopard (Neofelis nebulosa) has been sequenced using next generation sequencing technology Torrent PGM platform. The complete mitochondrial genome sequence of clouded leopard consists of 13 protein-coding, 22 tRNA, and two rRNA genes and a control region (CR). The mitochondrial genome is relatively similar to other felid mitochondrial genomes with respect to gene arrangement, composition, tRNA structures and skews of AT/GC bases to be typical of those reported for other mammals. The nucleotide composition of the genome shows that there is more A-T% than G-C% on the positive strand as revealed by positive AT and CG skews. The base composition of the mitochondrial genome of clouded leopard is as follows: A, 5362 bp (31.8%); C, 4560bp (27.0%); G, 2475 bp (14.6%); T, 4462 bp (26.4%). Most of the genes have ATG initiation codons, except ND1, ND2, ND3, ND4, ND6, and CYTB (ATA start codon).

Draft genome sequence of Bacillus okhensis Kh10-101T, a halo-alkali tolerant bacterium from Indian saltpan.

We report the 4.86-Mb draft genome sequence of Bacillus okhensis strain Kh10-101T, a halo-alkali tolerant rod shaped bacterium isolated from a salt pan near port of Okha, India. This bacterium is a potential model to study the molecular response of bacteria to salt as well as alkaline stress, as it thrives under both high salt and high pH conditions. The draft genome consist of 4,865,284 bp with 38.2% G + C, 4952 predicted CDS, 157 tRNAs and 8 rRNAs. Sequence was deposited at DDBJ/EMBL/GenBank under the project accession JRJU00000000.

Species identification from dried snake venom.

Illegal trade in snake parts has increased enormously. In spite of strict protection under wildlife act, a large number of snakes are being killed ruthlessly in India for venom and skin. Here, an interesting case involving confiscation of crystallized dried snake venom and subsequent DNA-based species identification is reported. The analysis using the universal primers for cytochrome b region of the mitochondrial DNA revealed that the venom was extracted from an Indian cobra (Naja naja). On the basis of this report, the forwarding authority booked a case in the court of law against the accused for illegal hunting of an endangered venomous snake and smuggling of snake venom. This approach thus has immense potential for rapid identification of snake species facing endangerment because of illegal trade. This is also the first report of DNA isolation from dried snake venom for species identification.
