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.
