Abstract

Polygonatum cirrhifolium (Wall.) Royle is a medicinal plant of commercial value. In the present study, we assembled the complete chloroplast genome of P. cirrhifolium. The total genome was a circular DNA molecule of 155,583 bp, which was made up of a large single copy region (84,412 bp), a small single copy region (18,427 bp), and a pair of inverted repeat regions (26,372 bp each). A total of 133 genes was annotated in the chloroplast genome, including 85 protein-coding genes, 40 transfer RNA (tRNA) genes, and eight ribosomal RNA (rRNA) genes. Overall, the chloroplast genome had a GC content of 37.66%. Phylogenetic analysis showed that P. cirrhifolium was closely related to P. kingianum.
