Figure 6.

Tf1 insertions cluster around the Ter1 motif in rDNA repeats but not the SAS1 site in the mating locus. (A) Top: Sequence of both strands of the SAS1 element. Bottom: Graph showing the number of Tf1 insertions at single-nucleotide positions within 1000 pb of the SAS1 sequence. (B) Top: Sequence of both strands of the Ter1 element. Bottom: Graph showing the alignment of the three published Ter1 motifs (Pombase.com) and the tabulated number of Tf1 insertions present at single-nucleotide positions within 1000 bp of the aligned Ter1 motifs. The nucleotides in bold indicate nucleotides within core motifs of the Ter1 and Sas1 sequence, as identified by Krings and Bastia (2006).
