Genealogy of Hebe genomic copies and phylogenetic placement of Hebe open reading frames (ORFs). (a) Neighbour-joining phylogram of 15 Hebe genomic copies (Table 1), designated as in Figure 1b, plus the majority-rule consensus sequence (Cons). Copies with deletions are indicated by Δ. Scale bar, nucleotide substitutions per site. (b, c) Neighbour-joining phylograms of (b) ORF2 from representatives of major non-long terminal repeat (non-LTR) retrotransposon clades, combining EN and RT domain sequences about 900 amino acids in length and (c) ORF1 coding for gag-like proteins from diverse non-LTR retrotransposons, about 500 aa in length. Clades are designated with square brackets. Scale bar, amino acid substitutions per site. Bootstrap support values from 1000 replications are indicated at the nodes.
