Figure 4.

High prevalence of repetitive sequences flanking the aspartyl protease-encoding genes.

The prevalence of repetitive sequences in the upstream and downstream 10kb regions flanking pepA and pop genes is depicted. The red bar denotes each gene locus while the repetitiveness of flanking regions is shown by blue bars. A log scale of 1 to 100 indicates repetitiveness scores for the flanking regions. For example, a score of 5 at a given position indicated that the 30mer at that position is found in five other locations in the genome. The Y-axis is logarithmic. The popA gene is offset from the center due to its proximity to the end of a genome assembly scaffold. Repetitiveness of zero is due to unknown sequences in the incomplete scaffold assembly. The popS gene is an example of a gene with no repetitive flanking sequences.
