From: Analysis of transcriptome data reveals multifactor constraint on codon usage in Taenia multiceps
Principal component analysis of relative synonymous codon usage in T. multiceps genes. The distribution of genes is shown along PC1 and PC2. A. Red dots, blue squares and green triangles indicate genes with G + C contents of less than 45%, more than or equal to 45%, but less than 60% and more than or equal to 60%, respectively. B. Blue dots, light green squares, red triangles, black squares and yellow squares indicate other genes, genes with a GRAVY value higher than 0.3, genes with an Aromo value greater than or equal to 0.15, essential genes and ribosomal genes
