　　Microsatellites or simple sequence repeats (SSRs) constitute a significant portion of genomes and play an important role in gene function and genome organization.The availability of a complete genome sequence for yak (Bos grunniens) has made it possible to carry out genome-wide analysis of microsatellites in this species.We analyzed the abundance and density of perfect SSRs in the yak genome.We found a total of 723,172 SSRs with 1-6 bp nucleotide motifs, indicating that about 0.47 % of the yak whole genome sequence (2.657 Gb) comprises perfect SSRs, the average length of which was 17.34 bp/Mb.
