Figure 4

A nested cluster of transposable elements on Mycosphaerella graminicola chromosome 6. A 47-kb nested cluster with an LTR retroelement as the base is indicated. It has a 5-bp target-site duplication (TGGAA). Each triangle represents one insertion and the numbers inside the triangle refer to the repeat family. This cluster only had class I elements. These elements have been shaded as follows: light grey, LTR retrotransposons; dark grey, Non-LTR retrotransposons. The bottom panel shows the percent GC plot for the corresponding repeat region. A decrease in percent GC content in the repeat region is evident when compared to the flanking DNA sequence.
