Computational identification of the selenocysteine tRNA (tRNASec) in genomes

tRNASec predictions in eukaryotic genomes.
(A) Phylogenetic tree of the eukaryotic genomes used in the benchmark set. Sec-containing species are drawn in bold font. The tRNASec predictions are indicated with dots. The size of each dot is proportional to the number of predictions. Open dots indicate a single prediction. The color of the cells indicate the outcome of the test, for each program. Species marked with a star (*) are discussed in the Results section and/or S1 Text. The approximate species phylogeny was obtained from the NCBI Taxonomy database (http://www.ncbi.nlm.nih.gov/taxonomy). Figure produced using our R package ggsunburst, available at http://genome.crg.es/∼dsantesmasses/ggsunburst. (B) Venn diagram showing the overlap between the tRNASec genes predicted by the three programs. Numbers in black correspond to predictions in Sec-containing genomes. Purple numbers correspond to predictions in Sec-devoid genomes.
