Genomic Characterization of Two Duck-Origin Picornaviruses with Seven 2A Peptides

Two novel picornavirus strains (NC0246 and PX0394) were isolated from breeding ducks experiencing reduced egg production. The genomic analysis reveals an unusual feature of seven distinct 2A polypeptides in each strain, which is considered rare within the Picornaviridae family. This 13.5 KB document, authored by Yuehua Gao and last updated in April 2026, details the genomic structure, homology, and phylogenetic relationships of these viruses.

Use Cases

• Studying the genetic diversity and evolution of picornaviruses based on the described amino acid deletions and homology comparisons.
• Analyzing the genomic structure of viruses with atypical 2A peptide arrangements based on the seven putative 2A peptides.
• Investigating viruses associated with reduced egg production in poultry based on the isolation context described.
• Performing phylogenetic analysis to clarify taxonomic relationships within the Aalivirus genus based on the described sister clade.

Strengths

• The dataset provides a detailed genomic characterization of two novel virus strains, including specific amino acid identity percentages (e.g., 37.37%, 64.44%).
• It highlights a distinctive and rare genomic feature: each strain possesses seven distinct 2A polypeptides.
• Includes a direct comparison between the two strains, noting a specific 73-amino-acid deletion in NC0246.

Limitations

• The dataset is a 13.5 KB DOCX document; the underlying genomic sequence data is not directly provided in a structured format.
• Row count and column-level documentation are absent; data structure must be inferred from the textual description.
• The geographic and temporal scope of the sample collection is not specified.
