Origin of subgenomes in the circumboreal, allopolyploid, carnivorous plant Drosera anglica.

Key Points

• The aim is to investigate the origin of subgenomes in the allopolyploid plant Drosera anglica.
• Analyzed allopolyploid relationships using phylogenomic data.
• Examined taxon sampling to understand subgenomic origins.
• Identified lineages from D. linearis and D. rotundifolia.
• Established that D. anglica results from allopolyploidy.
• Showed D. linearis as the major donor of plastid and ribosomal genes.
• Demonstrated the significance of taxon sampling in complex phylogenomic studies.
