A high-quality chromosomal-level genome assembly of Greater Scaup (Aythya marila) ...
Aythya marila is one of the few species of Anatidae, and the only Aythya to live in the circumpolar. However, there is a relative lack of research on genetics of this species. In this study, we reported and assembled the first high-quality chromosome-level genome assembly of A. marila . This genome...

| Summary: | Aythya marila is one of the few species of Anatidae, and the only Aythya to live in the circumpolar. However, there is a relative lack of research on genetics of this species. In this study, we reported and assembled the first high-quality chromosome-level genome assembly of A. marila . This genome was assembled using Nanopore long reads, and errors corrected using Illumina short reads, with a final genome size of 1.14 Gb, scaffold N50 of 85.44 Mb, and contig N50 of 32.46 Mb. 106 contigs were clustered and ordered onto 35 chromosomes based on Hi-C data, covering approximately 98.28% of the genome. BUSCO assessment showed that 97.1% of the highly conserved genes in aves_odb10 were present intact in the genome assembly. In addition, a total of 154.94 Mb of repetitive sequences were identified. 15,953 protein-coding genes were predicted in the genome, and 98.96% of genes were functionally annotated. This genome will be a valuable resource for future genetic diversity and genomics studies of A. marila . ... |
