Chloroplast Genome Sequencing and Comparative Analysis of Six Medicinal Plants of <i>Polygonatum</i>.

ABSTRACT: The genus Polygonatum boasts abundant germplasm resources and comprises numerous species. Among these, medicinal plants of this genus, which have a long history, have garnered attention of scholars. This study sequenced and analyzed the chloroplast genomes of six species of Polygonatum medicinal plants (P. zanlanscianense, P. kingianum, P. sibiricum, P. cyrtonema, P. filipes, and P. odoratum, respectively) to explore their interspecific relationships. The sequence length (154, 578-155, 807 bp) and genome structure were conserved among the six Polygonatum species, with a typical tetrad structure. Among the 127-131 genes contained in the genomes, 84-85 are protein-coding genes, 37-38 are transfer RNA genes, and 6-8 are ribosomal
