De Novo Transcriptome Assembly, Functional Annotation and SSR Marker Discovery of Qinling Takin ( Budorcas taxicolor bedfordi )

The takin ( ) is an endemic ruminant species belonging to the bovine family. The International Union for Conservation of Nature (IUCN) has listed it as an endangered and vulnerable species. However, little is known about its molecular characterization since it lacks a reference genome. This study used RNA sequencing followed by assembly, annotation and simple sequence repeats (SSRs) prediction to assess the transcriptome of Qinling takin ( ) muscles. In total, 21,648 unigenes with an N50 and mean length of 1388 bp and 817 bp, respectively, were successfully detected and annotated against the public databases (NR, GO, KEGG, and EggNOG). Furthermore, 6222 SSRs were identified using the MIcroSAtellite (MISA) identification tool software. Taken together, these findings will provide valuable information for genetic, genomic, and evolutionary studies on takin.
