Goat assembly and gene annotation

The domestic goat (Capra hircus) is a subspecies of goat domesticated from the wild goat of southwest Asia and Eastern Europe. The goat is a member of the family Bovidae and is closely related to the sheep, as both are in the goat-antelope subfamily Caprinae.

Goats are one of the oldest domesticated species, and have been used for their milk, meat, hair, and skins over much of the world. Studies of DNA evidence suggests 10,000 years BP as the domestication date.

Assembly

The ARS1 assembly was submitted by USDA ARS on 24/08/2016. The assembly is on the chromosome level, consisting of 30,399 contigs assembled into 29,907 scaffolds. The N50 size is the length such that 50% of the assembled genome lies in blocks of the N50 size or longer. The N50 length for the contigs is 26,244,591 bp while the scaffold N50 is 87,277,232 bp.

Gene annotation

The gene annotation process was carried out using a combination of protein-to-genome alignments, annotation mapping from a suitable reference species and RNA-seq alignments (where RNA-seq data with appropriate meta data were publicly available). For each candidate gene region, a selection process was applied to choose the most appropriate set of transcripts based on evolutionary distance, experimental evidence for the source data and quality of the alignments.
Small ncRNAs were obtained using a combination of BLAST and Infernal/RNAfold.
Pseudogenes were calculated by looking at genes with a large percentage of non-biological introns (introns of <10bp), where the gene was covered in repeats, or where the gene was single exon and evidence of a functional multi-exon paralog was found elsewhere in the genome.
lincRNAs were generated via RNA-seq data where no evidence of protein homology or protein domains could be found in the transcript.
