Phylogenetic analysis of S. cerevisiae Haa1 and Cup2 transcription factors homologues encoded in the genomes of 33 strains of 28 yeast species belonging to the Saccharomycetaceae family. a Radial phylogram showing the amino acid sequence similarity distances between these 51 full-size proteins. b Circular cladogram showing the tree topology, with the name of the S. cerevisiae and Z. bailii members indicated. MrBayes software suite was used in phylogenetic tree calculation using simulation statistical options described in materials and methods. The gene and species annotation adopted in this study uses the four letters code described in Table 1. The ORF teph_1_h00580, was chosen as outgroup due to the strong dissimilarity of its amino acid sequence when compared with those of the remaining members of this gene family
