RESUMO
Simple sequence repeats (SSRs) have been widely used for parentage testing, marker-assisted selection, and evolutionary studies. The insufficient availability of SSR markers in Bactrian camels partially accounts for the lack of systematic breeding. Therefore, we aimed to establish a comprehensive SSR dataset for the Bactrian camel. Our approach involved genome searching to locate every SSR in the genome, SSR-enriched sequencing to acquire polymorphism information, and literature research to collect published data. The resulting dataset contains 213,711 SSRs and details their characteristics, including genome coordinates, motifs, lengths, annotations, PCR primers, and polymorphism information. The dataset reveals a biased distribution of SSRs in the Bactrian camel genome, reflecting the mutation mechanism and complex evolution of SSRs. In practice, we successfully demonstrated the utility of the dataset through parentage testing using 15 randomly selected SSRs. This comprehensive dataset can facilitate systematic breeding and enable QTL mapping and GWAS of the Bactrian camel.
