Fig. 7

Structural comparison of the CPGs of 61 Aroideae species. Above the alignment, black arrows and bold black lines depict the orientation of genes, with each colour strip representing a different region: the blue strip for LSC, the orange strip for IRs, and the yellow strip for SSC. Peachblow strips indicate different chloroplast genomes, green bars indicate mismatches, and white bars represent insertions or deletions (indels).
