The Tvv1 retrotransposon family is conserved between plant genomes separated by over 100 million years

Key message Combining several different approaches, we have examined the structure, variability, and distribution of Tvv1 retrotransposons. Tvv1 is an unusual example of a low-copy retrotransposon metapopulation dispersed unevenly among very distant species and is promising for the development of molecular markers.
