Figure 3. Alu quiescence in the orangutan lineage.

Figure 3

We identified only ~250 lineage-specific Alu retroposition events in the orangutan genome, a dramatically lower rate than that of other sequenced primates, including humans. The total number of lineage-specific L1, SVA and Alu insertions is shown (pie chart), along with the rate of insertion events per element type (bar graph). Reduced Alu retroposition potentially limited the effect of a wide variety of repeat-driven mutational mechanisms in the orangutan lineage that played a major role in restructuring other primate genomes.
