Fig. 2From: Comparative analysis of the organelle genomes of Aconitum carmichaelii revealed structural and sequence differences and phylogenetic relationshipsRelative synonymous codon usage and ENC plotted against GC3s based on PCGs of A. carmichaelii organelle genes. A the chloroplast genes. B the mitochondrial gene. C the plastome PCGs. D the mitogenome PCGs. The solid line indicates the expected curve of positions of genes when the codon usage is merely determined by the GC3s compositionBack to article page
