Ecological niche modelling as a tool to identify candidate indigenous chicken ecotypes of Tigray (Ethiopia) (2022)
Journal Article

The Tigray region is an ancient entry route for the domestic chickens into Africa. The oldest African chicken bones were found in this region at Mezber, a pre-Aksumite rural farming settlement. They were dated to around 800–400 BCE. Since then, the f... Read More about Ecological niche modelling as a tool to identify candidate indigenous chicken ecotypes of Tigray (Ethiopia).

Influence of Eimeria maxima coccidia infection on gut microbiome diversity and composition of the jejunum and cecum of indigenous chicken (2022)
Journal Article

Coccidiosis is an economically significant protozoan disease and an intracellular parasite that significantly impacts poultry production. The gastrointestinal tract microbiota plays a central role in host health and metabolism, and these microbes enh...

Natural adaptation and human selection of northeast African sheep genomes (2022)
Journal Article

African sheep manifest diverse but distinct physio-anatomical traits, which are the outcomes of natural- and human-driven selection. Here, we generated 34.8 million variants from 150 indigenous northeast African sheep genomes sequenced at an average...

Ecological niche modelling for delineating livestock ecotypes and exploring environmental genomic adaptation: The example of Ethiopian village chicken (2022)
Journal Article

In evolutionary ecology, an “ecotype” is a population that is genetically adapted to specific environmental conditions. Environmental and genetic characterisation of livestock ecotypes can play a crucial role in conservation and breeding improvement,...

Genomic signatures for drylands adaptation at gene-rich regions in African zebu cattle (2022)
Journal Article

Background Indigenous Sudanese cattle are mainly indicine/zebu (humped) type. They thrive in the harshest dryland environments characterised by high temperatures, long seasonal dry periods, nutritional shortages, and vector disease challenges. Here,...

Whole genome sequences of 234 indigenous African chickens from Ethiopia (2022)
Journal Article

Indigenous chickens predominate poultry production in Africa. Although preferred for backyard farming because of their adaptability to harsh tropical environments, these populations suffer from relatively low productivity compared to commercial lines...

The usefulness of maternally inherited genetic markers for phylogeographic studies in village chicken (2022)
Journal Article

Phylogeography plays a major role in understanding micro and macroevolutionary processes dealing with evolutionary interpretations of geographical distribution. This field integrates information from molecular genetics, population genetics, demograph...

Mitonuclear incompatibility as a hidden driver behind the genome ancestry of African admixed cattle (2022)
Journal Article

Background: Africa is an important watershed in the genetic history of domestic cattle, as two lineages of modern cattle, Bos taurus and B. indicus, form distinct admixed cattle populations. Despite the predominant B. indicus nuclear ancestry of Afri... Read More about Mitonuclear incompatibility as a hidden driver behind the genome ancestry of African admixed cattle.

Whole-Genome Resequencing of Worldwide Wild and Domestic Sheep Elucidates Genetic Diversity, Introgression, and Agronomically Important Loci (2021)
Journal Article

Domestic sheep and their wild relatives harbor substantial genetic variants that can form the backbone of molecular breeding, but their genome landscapes remain understudied. Here, we present a comprehensive genome resource for wild ovine species, la...

Species and Phenotypic Distribution Models Reveal Population Differentiation in Ethiopian Indigenous Chickens (2021)
Journal Article

Smallholder poultry production dominated by indigenous chickens is an important source of livelihoods for most rural households in Ethiopia. The long history of domestication and the presence of diverse agroecologies in Ethiopia create unique opportu...

Population differentiated copy number variation of Bos taurus, Bos indicus and their African hybrids (2021)
Journal Article

Background: CNV comprises a large proportion in cattle genome and is associated with various traits. However, there were few population-scale comparison studies on cattle CNV. Results: Here, autosome-wide CNVs were called by read depth of NGS alignme... Read More about Population differentiated copy number variation of Bos taurus, Bos indicus and their African hybrids.

Large-scale genomic analysis reveals the genetic cost of chicken domestication (2021)
Journal Article

Background: Species domestication is generally characterized by the exploitation of high-impact mutations through processes that involve complex shifting demographics of domesticated species. These include not only inbreeding and artificial selection... Read More about Large-scale genomic analysis reveals the genetic cost of chicken domestication.

Domestic chicken diversity: Origin, distribution, and adaptation (2021)
Journal Article
