Figure 6. The NRPE1 tandem repeat array undergoes lineage-specific repeat expansions.

Figure 6

(a) Phylogenetic comparison of individual repeat units from Ar. thaliana (Ar. thal.), Ar. lyrata (Ar. lyr.) and Cap. rubella (Cap. rub.) reveals a tandem duplication of repeats 4-5-6 in the Cap. rubella lineage. (b) Similar analysis with Ne. paniculata (Ne. pani.) demonstrates an independent and complex duplication of a single repeat unit. Cladograms are ML trees with bootstrap support values from 100 replicates listed when ≥50. Branches supporting the duplications are marked with red dots. In the diagrams, repeat units (triangles) are numbered based on phylogenetic relationship to Arabidopsis repeats and colored to match clades above. Duplications are underlined and degenerated repeats that were not included in phylogenetic analysis are shown as red boxes.
