Phylogenetic reconstruction inferred based on the env-like protein (ENV) encoded by the Sire Ty1/Copia LTR retroelements using MEGA 4.1 (Kumar et al. 2008) and the Neighbor joining (NJ) method of phylogenetic reconstruction (Saitou and Nei 1987) with 100 bootstrap replicates under the conditions: uniform rates among sites and pairwise deletion of gaps.
