Figure 1From: Homology-based annotation of non-coding RNAs in the genomes of Schistosoma mansoni and Schistosoma japonicumComparison of the tRNA complement of Schistosoma mansoni , Schistosoma japonicum , and Schmidtea mediterranea. A: Comparison of anti-codon distributions for the 20 amino acids. Numbers below each pie-chart are the total number of tRNA genes coding the corresponding amino acid. Left columns: S. mansoni; middle columns: S. mediterranea; right columns: S. japonicum. B: Number of tRNAs encoding a particular amino acid. red: S. mansoni, blue: S. japonicum, green: S. mediterranea. Abbreviations: Sup: putative suppressor tRNAs (CTA, TTA); Scys: Selenocysteine tRNAs (TCA); Pseu: predicted pseudogenes; Und: tRNA predictions with uncertain anticodon; likely these are also tRNA pseudogenes. The Gln-tRNA derived repeat family (see text) is not included in these data. C: Comparison of codon usage and anti-codon abundance. No significant correlation is observed for the two schistosomes. For S. mediterranea there is a weak, but statistically significant, positive correlation: t ≈ 2.0Back to article page
