Abstract:
Copy number variation (CNV) refers to a kind of structural variation, having functional and evolutionary effects on phenotypes. Thus far, further elucidation of the CNVs in different Chinese indigenous cattle breeds by whole genome sequencing have yet not been done. In this study, a comprehensive genomic analysis was performed on 75 cattle individuals including six Chinese indigenous cattle breeds and two non-native specialized beef cattle breeds. Based on the 11,486 CNVRs discovered, population analysis was performed, showed that all the cattle breeds clustered in to three clades, consistent with their lineages Bos taurus, Bos taurus × Bos indicus and Bos indicus. Importantly, a set of CNVRs related genes were found to be associated with the traits of interest, which include meat production or quality (CAST, ACTC1, etc.), adaption (BLA-DQB, EGLN2, etc.) and coat color (KIT, MITF, etc.). These results provide valuable full genome variation resources for Chinese bovine genome research and would be helpful for cattle breeding and selection programs in the future.
