The complete chloroplast genome of Arisaema bockii Engler and its phylogenetic analysis in the family Araceae

Abstract

Arisaema bockii Engler is a perennial herbaceous medicinal plant, which is widely distributed in many provinces in China such as Anhui, Jiangsu, and Zhejiang. In this study, the complete chloroplast genome sequence of A. bockii was assembled and characterized based on high-throughput sequencing data. The total length of chloroplast genome was 175,537 bp, including large single-copy (LSC) and small single-copy (SSC) regions of 98,870 bp and 23,345 bp, respectively, which were separated by a pair of 27,161 bp inverted repeat (IR) regions. The genome contained 129 genes, including 84 protein-coding genes, 36 tRNA genes, 8 rRNA genes, and one pseudogene. The overall GC content of the genome was 33.6%. A phylogenetic tree reconstructed by 30 chloroplast genomes revealed that A. bockii was mostly related to the same genus species A. ringens, A. franchetianum and A. erubescens. The work reported the first complete chloroplast genome of A. bockii, which may provide some useful information to the evolution of the family Araceae.
