Retand LTR-retrotransposons in plants: a long way from pol to 3'LTR.

ABSTRACT:

Background

Plant Gypsy LTR-retrotransposons are classified into lineages according to the phylogenetic relationships of the reverse transcriptase. Retand is a lineage of non-chromovirus elements characterized by the presence of a long internal region compared to other lineages.

Results

This work focuses on the identification and characterization of Potentially Recently Active Retand Elements (PRAREs) in 617 genomic sequence assemblies of Viridiplantae species. The Retand elements were considered PRAREs if their LTRs and insertion sequences were identical, and the sizes of their internal regions and LTRs did not differ by more than 2% from the consensus. A total of 2,735 PRAREs were identified, distributed in 122 clusters corresponding to 34 species, with copy numbers per clu
