Whole-Genome Analysis Deciphers Population Structure and Genetic Introgression Among Bovine Species.

It is known that throughout history and presently, taurine () and indicine/zebu () cattle were crossed with other bovine species (e.g., gayal, gaur, banteng, yak, wisent, and bison).

Genomic Analysis Reveals Subdivision of Black Rats () in India, Origin of the Worldwide Species Spread.

In contrast to the detailed and globally extensive studies on the spread of the commensal black rat, , there has been relatively little work on the phylogeography of the species within India, from where this spread originated. Taking a genomic approach, we typed 27 samples from Peninsular India using the genotyping-by-sequencing (GBS) method. Filtering and alignment of the FASTQ files yielded 1499 genome-wide SNPs.

VARV B22R homologue as phylogenetic marker gene for Capripoxvirus classification and divergence time dating.

Sheeppox disease is associated with significant losses in sheep production world over. The sheep pox virus, the goatpox virus, and the lumpy skin disease virus cannot be distinguished by conventional serological tests. Identification of these pathogens needs molecular methods.

Genome sequencing of an Indian peste des petits ruminants virus isolate, Izatnagar/94, and its implications for virus diversity, divergence and phylogeography.

Peste des petits ruminants is an important transboundary disease infecting small ruminants. Genome or gene sequence analysis enriches our knowledge about the evolution and transboundary nature of the causative agent of this disease, peste des petits ruminants virus (PPRV). Although analysis using whole genome sequences of pathogens leads to more precise phylogenetic relationships, when compared to individual genes or partial sequences, there is still a need to identify specific genes/genomic regions that can provide evolutionary assessments consistent with those predicted with full-length genome sequences.

Mitochondrial DNA analyses revealed low genetic diversity in the endangered Indian wild ass Equus hemionus khur.

The Indian wild ass Equus hemionus khur, belonging to ass-like equid branch, inhabits the dry and arid desert of the Little Rann of Kutch, Gujarat. The E. h.

Genetic differentiations between randomly and selectively bred pig populations in Yunnan, China.

To assess the genetic diversity between randomly and selectively bred populations, we sequenced 438 bp of the mitochondrial DNA control region from 102 pigs. These samples represented four native pig breeds, one nucleus and one conservation herd from Yunnan, China. Twenty haplotypes with sixteen polymorphic sites were identified.

Genetic affinities within a large global collection of pathogenic Leptospira: implications for strain identification and molecular epidemiology.

Leptospirosis is an important zoonosis with widespread human health implications. The non-availability of accurate identification methods for the individualization of different Leptospira for outbreak investigations poses bountiful problems in the disease control arena. We harnessed fluorescent amplified fragment length polymorphism analysis (FAFLP) for Leptospira and investigated its utility in establishing genetic relationships among 271 isolates in the context of species level assignments of our global collection of isolates and strains obtained from a diverse array of hosts.

Zebu cattle are an exclusive legacy of the South Asia neolithic.

Animal domestication was a major step forward in human prehistory, contributing to the emergence of more complex societies. At the time of the Neolithic transition, zebu cattle (Bos indicus) were probably the most abundant and important domestic livestock species in Southern Asia. Although archaeological evidence points toward the domestication of zebu cattle within the Indian subcontinent, the exact geographic origins and phylogenetic history of zebu cattle remains uncertain.

Multiple maternal origins of chickens: out of the Asian jungles.

Domestic chickens have long been important to human societies for food, religion, entertainment, and decorative uses, yet the origins and phylogeography of chickens through Eurasia remain uncertain. Here, we assessed their origins and phylogeographic history by analyzing the mitochondrial DNA hypervariable segment I (HVS-I) for 834 domestic chickens (Gallus gallus domesticus) across Eurasia as well as 66 wild red jungle fowls (Gallus gallus) from Southeast Asia and China. Phylogenetic analyses revealed nine highly divergent mtDNA clades (A-I) in which seven clades contained both the red jungle fowls and domestic chickens.
