Trees of the serine and leucine tRNAs of Candida albicans,Saccharomyces cerevisiae, Candida cylindracea, andSchizosaccharomyces pombe with the C. albicansSer-tRNA_CAG. (A) Tree of the serine and leucine tRNAs of C. albicans. (B) Tree of the serine and leucine tRNAs of S. cerevisiae. (C) Tree of the serine and leucine tRNAs of C. cylindracea. (D) Tree of the serine and leucine tRNAs of S. pombe. Trees were constructed using the NJ method and the Kimura 2-parameter distance model (Kimura 1980). The γ shape parameter used was 0.623 for C. albicans, 0.400 for C. cylindracea, 0.833 for S. cerevisiae, and 0.698 for S. pombe. (CACAG) The C. albicans Ser-tRNA_CAG. The numerals represent the confidence levels from 100 bootstrap replicates. The tRNA sequences used for A are displayed athttp://www.bio.ua.pt/genomica/Lab/Genomedata.html. The tRNA sequences used for B, C, and D were obtained from GenBank. The scale represents the average number of substitutions per site.
