Alignment of chloroplast genomes of Heteropolygonatum alternicirrhosum, H. ginfushanicum, Polygonatum campanulatum, P. filipes1, P. franchetii, P. zanlanscianense1, P. cyrtonema1, P. sibiricum1, P. kingianum2. The grey arrows at the top represent the direction of gene translation, and the y-axis indicates the percentage identity between 50 and 100%. (Exon: protein codes; UTR: tRNAs and rRNAs; CNS: conserved noncoding sequences).
