Figure 1.

Classification of the 21 novel full-length retrotransposon sequences into 10 families. The Neighbor-Joining tree is based on the multiple sequence alignment of amino acid sequences between reverse transcriptase domains I and VII using the Poisson distance model. * Insertions displaying perfect target duplication sites. Ty1/copia retrotransposons Tvv1 from grapevine and Hopscotch from maize (acc. n° U12626) were added as references. Bootstrap values greater than 60% are shown on the tree.
