  • Genomic Signatures of Adaptive Introgression from European
    www.nature.com/scientificreports OPEN Genomic signatures of adaptive introgression from European moufon into domestic sheep Received: 23 September 2016 Mario Barbato 1,2, Frank Hailer2, Pablo Orozco-terWengel 2, James Kijas3, Paolo Mereu 4, Accepted: 22 June 2017 Pierangela Cabras5, Rafaele Mazza6, Monica Pirastru 4 & Michael W. Bruford2 Published: xx xx xxxx Moufon (Ovis aries musimon) became extinct from mainland Europe after the Neolithic, but remnant populations from the Mediterranean islands of Corsica and Sardinia have been used for reintroductions across Europe since the 19th-century. Moufon x sheep hybrids are larger-bodied than moufon, potentially showing increased male reproductive success, but little is known about genomic levels of admixture, or about the adaptive signifcance of introgression between resident moufon and local sheep breeds. Here we analysed Ovine medium-density SNP array genotypes of 92 moufon from six geographic regions, along with data from 330 individuals of 16 domestic sheep breeds. We found lower levels of genetic diversity in moufon than in domestic sheep, consistent with past bottlenecks in moufon. Introgression signals were bidirectional and afected most moufon and sheep populations, being strongest in one Sardinian moufon population. Developing and using a novel approach to identify chromosomal regions with consistent introgression signals, we infer adaptive introgression from moufon to domestic sheep related to immunity mechanisms, but not in the opposite direction. Further, we infer that Soay and Sarda sheep carry introgressed moufon alleles involved in bitter taste perception and/or innate immunity. Our results illustrate the potential for adaptive introgression even among recently diverged populations. Introgression is increasingly documented as a potentially adaptive evolutionary force1, with recent developments in high-throughput genotyping and sequencing facilitating the detection of even small genomic regions that have been passed on from one taxon to another2.

The melanocortin 1 receptor (MC1R) gene has been described as responsible for the black color in some breeds of sheep, but little is known about its function in many colored breeds, particularly those with a wide range of pigmentation phenotypes. The Brazilian Creole is a local breed of sheep from southern Brazil that has a wide variety of wool colors. We examined the MC1R gene (Extension locus) to search for the e allele and determine its role in controlling wool color variation in this breed. One hundred and twenty-five animals, covering the most common Creole sheep phenotypes (black, brown, dark gray, light gray, and white), were sequenced to detect the mutations p.M73K and p.D121N. Besides these two mutations, three other synonymous sites (429, 600, and 725) were found.
