The Japanese quail has several advantages as a laboratory animal for biological and biomedical investigations. In this study, the draft genome of the Japanese quail was sequenced and assembled using next-generation sequencing technology. To improve the quality of the assembly, the sequence reads from the Japanese quail were aligned against the reference genome of the chicken. The final draft assembly consisted of 1.75Gbp with an N50 contig length of 11,409bp. On the basis of the draft genome sequence obtained, we developed 100 microsatellite markers and used these markers to evaluate the genetic variability and diversity of 11 lines of Japanese quail. Furthermore, we identified Japanese quail orthologs of spermatogenesis markers and analyzed their expression using in situ hybridization. The Japanese quail genome sequence obtained in the present study could enhance the value of this species …
