Phylogenetic analyses of the Saccharomyces sensu stricto group. A phylogenetic tree of the sensu stricto Saccharomyces species places S. arboricolus between S. bayanus and S. kudriavzevii. Tree topology was obtained using random concatenations of protein sequences with S. castellii as the outgroup. Branch lengths represent the maximal likelihood estimate of the evolutionary distance in DNA substitutions per codon using all genes that we identified as ‘syntenic orthologs’.
