The drastic change in global climate has led to in-depth studies of the geneticresources of native cattle adapted to challenging environments. Native cattle breeds may harbor unique genetic mechanisms that have enabled them adapt to their given environmental conditions. Adipose tissues are key factors in the regulation of metabolism and energy balance and are crucial for the molecular switches needed to adapt to rapid environmental and nutritional changes.

Finnhorse is Finland's native and national horse breed and it has genetic affinities to northern European and Asian horses. It has historical importance for agriculture, forest work and transport and as a war horse. Finnhorse has four breeding sections in the studbook and is under conservation and characterisation efforts.

Reindeer, called caribou in North America, has a circumpolar distribution and all extant populations belong to the same species (). It has survived the Holocene thanks to its immense adaptability and successful coexistence with humans in different forms of hunting and herding cultures. Here, we examine the paternal and maternal history of based on robust Y-chromosomal and mitochondrial DNA (mtDNA) trees representing Eurasian tundra reindeer, Finnish forest reindeer, Svalbard reindeer, Alaska tundra caribou, and woodland caribou.

Article Synopsis
  • Domestic reindeer are crucial for the culture and economy of indigenous peoples in northern Eurasia, thriving in harsh environments, which highlights the need to understand their genomics for better management and conservation.
  • The study presented a new, highly complete genome assembly for Fennoscandian domestic reindeer, allowing for extensive exploration of genetic diversity and population structure across various reindeer populations in Eurasia.
  • Results revealed four main genetic clusters among reindeer populations, indicating two separate domestication processes and showing genetic distinctions, especially with the Finnish forest reindeer identified as a unique subspecies.

Reindeer are native to harsh northern Eurasian environments which are characterized by long and cold winters, short summers, and limited pasture vegetation. Adipose tissues play a significant role in these animals by modulating energy metabolism, immunity, and reproduction. Here, we have investigated the transcriptome profiles of metacarpal, perirenal, and prescapular adipose tissues in Even reindeer and searched for genes that were differentially expressed in male and female individuals.
