First record of the complete chloroplast genome of Polygonatum infundiflorum (Asparagaceae), a Korean endemic species

Abstract

Polygonatum infundiflorum Y.S. Kim, B.U. Oh & C.G. Jang et al. is a Korean endemic species. This is first report on the complete chloroplast genome sequence of P. infundiflorum. The complete chloroplast genome length was 154,578 bp with a GC content of 37.7%. The large single-copy (LSC) region was 83,527 bp long, and the small single-copy (SSC) region was 18,457 bp long. The paired inverted repeats (IRs) were 26,297 bp and separated the LCS and SSC regions. There were 113 genes, comprising 78 protein-coding genes, four rRNA genes, 30 tRNA genes, and one pseudogene (infA). In total, 16 genes contained one intron, and two genes contained two introns. Phylogenetic analysis suggested that Polygonatum was divided into three sections, each forming a monophyletic group. P. infundiflorum was sister to P. macropodum and formed a monophyletic group with P. inflatum. This study provides basic information for future research and contributes to taxonomic and genetic studies on Polygonatum.
