Figure 2.
Phylogenetic analysis of a cluster of CentO monomers surrounding the first two CRRs in the core region of CEN4. (A) Neighbor-Joining tree obtained with the monomer sequence data. (Filled circles) Closely related monomers with bootstrap values >80% based on 500 replicates, (open circles) other monomers without clear relationship. (B) A segmental duplication event revealed by the Neighbor-Joining tree. The closely related pairs of monomers are connected, respectively, by short vertical lines. The integration sites of the noaCRR1 elements are marked by dark arrows. (C) A subregion of the alignment of the monomers analyzed above showing a 10-bp duplication site.
