Fig. 4

Schematic diagram of gene annotations for the chloroplast and mitochondrial genomes of C. speciosa. The diagram illustrates the positional relationships among genes within the circular genomes of the chloroplasts (a) and mitochondria (b). The gene types displayed in each genome are specified in the legends corresponding to each genome. The track within the inner circle indicates the guanine (GC) ratio (dark color). For the chloroplast genome, the small single-copy (SSC), large single-copy (LSC), and inverted repeat regions (IRA and IRB) are illustrated in the inner circle.
