United KingdomA study led by researchers from INRAE and CIRAD explored the history of ancient viruses by analyzing plant genomes for molecular remnants called endogenous viral elements. These genetic fragments, inherited over millions of years, provide insights into the evolutionary relationships between viruses and their plant hosts. Focusing on the Caulimoviridae virus family, the team examined 93 plant species across various lineages and identified over 47,000 viral elements, revealing 35 previously unknown taxonomic groups. The findings suggest that these viruses have co-evolved with vascular plants for hundreds of millions of years, though their relationship has involved host switching and extinction events linked to major geological changes like the Permian and Cretaceous mass extinctions. This research highlights the importance of plant genomes as archives of viral evolution.
