Figure 1.
Genomic context of the Spok block. (A) An alignment of the region where the Spok block is located in the strain Wa137 (Psk-9) from all P. anserina genomes analyzed herein. The putative target site duplication (TSD) is highlighted. Only the ends of the Spok block are shown for clarity. (B) An alignment of the ends of four versions of the Spok block displaying the TSD (pink trapezoid) and an imperfect palindromic motif (magenta). The flanks of the Spok block that relate to the unclassified repeats bufo and schoutedenella are underlined in red and blue, respectively. Note that for Psk-7, the Spok block is inserted immediately next to a truncated bufo element.
