Figure 3.

The two CRISPR loci of OG1RF. (a) The CRISPR1 locus. The CRISPR1 element is represented with a hatched box while the CRISPR1 associated genes are represented in orange; the white arrows indicate ORFs present in both OG1RF and V583. The black diamonds represent the 37 bp repeat sequences, while the open boxes with a number indicate the 29 bp unique sequences. (b) The CRISPR2 locus containing only a CRISPR element. (c) CRISPR consensus and unique sequences. The underlined bases indicate mismatches at these locations. The sequences numbered 1 to 14 represent the unique sequences located in the CRISPR1 and CRISPR2 elements.
