Fig. 2From: Comparative genomics of 11 complete chloroplast genomes of Senecioneae (Asteraceae) species: DNA barcodes and phylogeneticsDetails of codon usage biasness in the chloroplast genomes of five species of Senecio and six species of Dendrosenecio. The values at the top of each stack indicate the usage frequency of each amino acid, while the bars (colour coded) depicts the relative synonymous codon usage values for each codonBack to article page
