Phylogenetic tree of Chromoviridae elements. The tree was constructed from a Jukes-Cantor distance matrix of the reverse transcriptase domains of Ty3/gypsy Chromoviridae elements described in Neumann et al. [34] and Fesreba elements identified in the present work with BioNJ implemented in Seaview [5]. The tree was rooted on the Ty3/gypsy/Tat element. The subclade of the Cereba element (in red) and other closely related elements identified in different plant species are labeled in blue. Fesreba elements identified in fescues and ryegrasses are also marked in blue
