Título: | Y-Chromosome Analysis in Retuertas Horses |
Autor: | Brandariz-Fontes, Claudia CSIC; Leonard, Jennifer A. CSIC ORCID; Vega-Pla, J.L.; Backström, N.; Lindgren, G.; Rico, Ciro CSIC ORCID | Fecha de publicación: | 2013 | Editor: | Public Library of Science | Citación: | PLoS ONE, 8(5): e64985 (2013) | Resumen: | Several studies based on a variety of genetic markers have attempted to establish the origins of horse domestication. Thus far a discrepancy between the results of mitochondrial DNA analysis, which show high levels of diversity, and results from the Y-chromosome, with almost no genetic variability, has been identified. Most previous work on the horse Y-chromosome has focused on widespread, popular breeds or local Asian breeds. It is possible that these breeds represent a reduced set of the genetic variation present in the species. Additional genetic variation may be present in local breeds and ancient feral populations, such as the Retuertas horse in Spain. In this study we analyzed the Y-chromosome of the Retuertas horse, a feral horse population on the Iberian Peninsula that is at least several hundred years old, and whose genetic diversity and morphology suggests that it has been reproductively isolated for a long time. Data from the Retuertas horse was compared to another 11 breeds from the region (Portugal, Spain and France) or likely of Iberian origin, and then to data from 15 more breeds from around the globe. We sequenced 31 introns, Zinc finger Y-chromosomal protein (ZFY) and anonymous Y-linked fragments and genotyped 6 microsatellite loci found on the Y-chromosome. We found no sequence variation among all individuals and all breeds studied. However, fifteen differences were discovered between our data set and reference sequences in GenBank. We show that these likely represent errors within the deposited sequences, and suggest that they should not be used as comparative data for future projects. | Versión del editor: | http://dx.doi.org/10.1371/journal.pone.0064985 | URI: | http://hdl.handle.net/10261/78279 | DOI: | 10.1371/journal.pone.0064985 |
