Horizontal Transfer of Transposons Identified as Key Source of New Introns

Rapid Summary

• The study, published in the Proceedings of the National Academy of Sciences (Volume 122, Issue 21, May 2025), examines introns within eukaryotic genomes.
• Introns are ample components of these genomes and have origins that remain largely unclear.
• The research highlights “introners,” a type of transposable element (TE), as potential contributors to intron formation across various biological lineages.
