Codon usage of the secretome. Codon usage was analysed across the set of macroschizont expressed T. annulata genes encoding a signal peptide with an orthologue in T. parva (n = 218). Correspondence analysis was used to transform the data in order to explore variation in codon usage among these genes. 33% of the variation present in the dataset is illustrated on the graph as the first two principal components of the analysis and this clearly shows that SVSP-encoding genes display atypical codon usage.
