Duck assembly and gene annotation


This release features the first draft assembly of the mallard duck (Anas platyrhynchos) genome, BGI_duck_1.0, submitted by the State Key Laboratory for Agrobiotechnology, China Agricultural University, Beijing in April 2013. The assembly comprises 78487 toplevel sequences, all of which are unplaced scaffolds (from 227448 contigs). The N50 of the contigs is 26 kb and the N50 of the scaffolds is 1.2 Mb. The N50 size is the length such that 50% of the assembled genome lies in blocks of the N50 size or longer.

The genome assembly represented here corresponds to GenBank Assembly ID GCA_000355885.1

Gene annotation

Annotation was performed using the EnsEMBL annotation pipeline, with the gene set being supplemented by the projection of orthologous genes and the inclusion of genes based on alignments with lower coverage than usual. The gene set contains 15,634 protein coding genes, 249 pseudogenes and 567 ncRNAs.
