Article Synopsis
  • The study investigates the genetic mechanisms behind the phenotypic variation in domesticated sheep by sequencing the genomes of 100 sheep across 10 breeds and integrating this data with information from 225 additional sheep.
  • Results show domesticated sheep formed a distinct genetic group, with Chinese indigenous breeds having a specific geographical distribution.
  • Key findings identify selective genes linked to immune response, visual function, pigmentation, energy metabolism, and growth, revealing the genetic basis for breed characteristics and phenotypic changes during sheep domestication and improvement.

Melatonin plays crucial roles in a wide range of ovarian physiological functions via the melatonin receptors (MRs). Structure and function of MRs have been well studied in sheep, cattle, and humans, but little information exists on the genetic characterization and function of these receptors in the ovary of the white yak. In the present study, the melatonin receptor MT1 was cloned by RT-PCR in the ovary of white yak; the MT1 cDNA fragment obtained (843bp) comprised an open reading frame (827bp) encoding a protein containing 275 residues, characterized by seven transmembrane regions and an NRY motif, two distinct amino acid replacements were found.

Determination of the transcription level of cellular prion protein (PrP(C)) is essential for understanding its role in organisms and revealing mechanism of susceptibility and resistance to scrapie. However, the expression of prion protein (PrP) mRNA in sheep has not been quantified in great detail in digestive tract which is important during scrapie spread through oral route. Herein, we report on measurement of sheep PrP mRNA using absolute quantitative real-time RT-PCR.
