The complete chloroplast genome of Piper sarmentosum Roxburgh, 1820 (Piperaceae)

Abstract

Piper sarmentosum Roxb. (Piperaceae) is a traditional medicinal herb native to Southeast Asia. The complete genome of P. sarmentosum was sequenced and characterized in this study with the aim of providing genomic resources for the evolution and molecular breeding of P. sarmentosum. It has a typical quadripartite structure, with a large single-copy (LSC) region of 88,979 bp, a small single-copy (SSC) region of 18,274 bp, and two copies of 27,068 bp inverted-repeat regions (IRa and IRb). A total of 130 genes were annotated, comprising 85 protein-coding genes (PCGs), 8 ribosomal RNA (rRNA) genes, and 37 transfer RNA (tRNA) genes. The phylogenetic tree showed that P. sarmentosum in the current study is closely related to Piper longum.
