The complete chloroplast genome sequence of herb Nardostachys jatamans (family: Valerianaceae) in China

Abstract

Nardostachys jatamans is an endemic herb in China, distributes mainly in Southeast Gansu, South Qinghai and West Sichuan of Qinghai-Tibet Plateau. In this study, the complete chloroplast genome (a typical quadripartite structure) sequence of N. jatamans was reported. The length of the DNA molecule was 155,268 bp with a large single-copy region (LSC: 87,263 bp), small single-copy region (SSC: 17,327 bp) and inverted repeats (IRa and IRb: 25,339 bp). The overall GC content was 38.56%. It has a total of 129 genes, containing 83 protein-coding genes, 38 tRNA genes, and eight rRNA genes. The phylogenetic analysis has shown that N. jatamans is sister to Valeriana offcinalis. The chloroplast genome provides the basis for development and utilization of N. jatamans in future.
