Sequencing and phylogenetic analysis of the complete chloroplast genome of Arisaema heterophyllum Blume

Abstract

Arisaema heterophyllum Blume is a perennial medicinal herb widely distributed in China, Korea and Japan. In this study, the complete chloroplast genome sequence of A. heterophyllum was assembled and characterized based on high-throughput sequencing data. The whole chloroplast genome is 170,610 bp in length and contains 95,485 bp large single-copy (LSC) and 22,605 bp small single-copy (SSC) regions separated by a pair of 26,260 bp inverted repeat (IR) regions. It contained a total of 129 genes, including 84 protein-coding genes, 37 tRNA genes, and 8 rRNA genes, with an overall GC content of 34.5%. A phylogenetic tree reconstructed by 30 chloroplast genomes reveals that A. heterophyllum is mostly related to the same genus A. ringens, A. franchetianum and A. erubescens. The complete chloroplast genome of A. heterophyllum was the firstly reported and deposited at GenBank under accession number MZ424448.
