Genome-wide analysis reveals the extent of EAV-HP integration in domestic chicken
Background: EAV-HP is an ancient retrovirus pre-dating Gallus speciation, which continues to circulate in modern
chicken populations, and led to the emergence of avian leukosis virus subgroup J causing significant economic ...
Signatures of positive selection in African Butana and Kenana dairy zebu cattle
Butana and Kenana are two types of zebu cattle found in Sudan. They are unique amongst
African indigenous zebu cattle because of their high milk production. Aiming to understand
their genome structure, we genotyped 25 ...
Ancient and modern DNA reveal dynamics of domestication and cross-continental dispersal of the dromedary
Dromedaries have been fundamental to the development of human societies in arid landscapes and for long-distance trade across hostile hot terrains for 3,000 y. Today they continue to be an important livestock resource in ...
Whole-Genome Resequencing of Red Junglefowl and Indigenous Village Chicken Reveal New Insights on the Genome Dynamics of the Species
The red junglefowl Gallus gallus is the main progenitor of domestic chicken, the
commonest livestock species, outnumbering humans by an approximate ratio of six
to one. The genetic control for production traits have been ...
Whole-genome resequencing of wild and domestic sheep identifies genes associated with morphological and agronomic traits
Understanding the genetic changes underlying phenotypic variation in sheep (Ovis aries) may facilitate our efforts towards further improvement. Here, we report the deep resequencing of 248 sheep including the wild ancestor ...
Mitochondrial and nuclear multilocus phylogeny of Rhipicephalus ticks from Kenya
The morphological diversity of African ticks of the genus Rhipicephalus and subgenus Boophilus have been studied in detail. However, their taxonomy remains poorly resolved with limited molecular studies performed to improve ...
The maternal origin of indigenous domestic chicken from the Middle East, the north and the horn of Africa
Indigenous domestic chicken represents a major source of protein for agricultural communities around the world. In the Middle East and Africa, they are adapted to hot dry and semi-dry areas, in contrast to their wild ...
Polymorphisms in MC1R and ASIP Genes are Associated with Coat Color Variation in the Arabian Camel
Pigmentation in mammals is primarily determined by the distribution of eumelanin and
pheomelanin, the ratio of which is mostly controlled by the activity of melanocortin 1 receptor
(MC1R) and agouti signaling protein (ASIP) ...
Historical Introgression from Wild Relatives Enhanced Climatic Adaptation and Resistance to Pneumonia in Sheep
How animals, particularly livestock, adapt to various climates and environments over short evolutionary time is of fundamental biological interest. Further, understanding the genetic mechanisms of adaptation in indigenous ...
Paternal Origins and Migratory Episodes of Domestic Sheep
The domestication and subsequent global dispersal of livestock are crucial events in human history, but the migratory episodes during the history of livestock remain poorly documented [1, 2, 3]. Here, we first developed a ...
