Abstract:
Ancient DNA (aDNA) provides direct evidence of historical events that have modelled the genome of modern individuals. In livestock, resolving the differences between the effects of initial domestication and of subsequent modern breeding is not straight forward without aDNA data. Here, we have obtained shotgun genome sequence data from a sixteenth century pig from North-eastern Spain (Montsoriu castle), the ancient pig was obtained from an extremely well-preserved and diverse assemblage. In addition, we provide the sequence of three new modern genomes from an Iberian pig, Spanish wild boar and a Guatemalan Creole pig. Comparison with both mitochondrial and autosomal genome data shows that the ancient pig is closely related to extant Iberian pigs and to European wild boar. Although the ancient sample was clearly domestic, admixture with wild boar also occurred, according to the D-statistics. The close relationship between Iberian, European wild boar and the ancient pig confirms that Asian introgression in modern Iberian pigs has not existed or has been negligible. In contrast, the Guatemalan Creole pig clusters apart from the Iberian pig genome, likely due to introgression from international breeds.
About Prof. Miguel Perez-Enciso:
Miguel Perez-Enciso (PhD 1990, Universidad Complutense, Madrid, Spain) is an ICREA researcher, a prestigious Spanish research organisation, and is associated with Centre for Research in Agricultural Genomics. Previously, he had worked in INRA (France), IRTA (Lleida, Spain) and Universities of Wisconsin Madison and of Illinois Urbana-Champaign. He is currently visiting CSIRO at UQ campus under a Mcmaster fellowship.
Miguel Perez-Enciso is a biologist by training that has developed his career in the area of Animal Breeding and genetics, primarily in methodological developments and applications to pig breeding. He is currently working actively in the applications of NGS technologies, both RNAseq and genome re-sequencing. His current work encompasses both method and experimental approaches, the latter being focused in pig and Iberian pig genetics.
