Figure 2. Architectures of canonical and variant cas gene sets.
Genes are shown as arrows pointing in the direction of transcription. Grey shadows highlight the distinguishing features of the variants I-ES1, I-ES2, and I-F1S1. Species in which the architectures were detected are reported on the right side and the number of genomes is reported in brackets. Truncated cas gene sets (due to end of contigs) were not shown. (A) Genetic organization of the canonicalcas gene set I-C. (B) Genetic organization of cas gene sets for the canonical I-E and the variants I-ES1 and I-ES2. The WYL domain is highlighted as a red arrow. (C) Genetic organization ofcas gene sets for the canonical I-F1 and the variant I-F1S1.
