The phylogeny and conservation of cas genes. (a,b) Phylogeny of cas genes across Salmonella serovars for entire cas operon (a) and the cas3 gene (b). The sequences were aligned using MUSCLE, and the phylogenetic trees were constructed by ML. (c) Conservation of all the individual cas gene and Cas protein sequences. The amino acid percent conservation is depicted in parenthesis. The term ‘ND’ represents no nucleotide sequence similarity based on the default parameter of the tool Nucleotide-BLAST. The bootstrap values are indicated at each node. The reference strains used were S. enterica subsp. enterica serovar Typhimurium str.14028S, Typhi str. CT18, S. enterica subsp. arizonae str. NCTC10047, S. enterica subsp. diarizonae str. MZ0080 and S. bongori str. SA19983605.
