Key Findings
- Researchers in Korea discovered two new viruses in echinacea seeds, named Echinacea-associated tombusviruses 1 and 2 (EaTV1 and EaTV2)
- These viruses belong to the Tombusviridae family and share features like RNA-dependent RNA polymerases and coat proteins, essential for viral replication
- EaTV1 and EaTV2 show close evolutionary ties with oat chlorotic stunt virus and other unassigned tombusviruses, suggesting complex evolutionary pathways
