Abstract

Acorus tatarinowii is a useful traditional Chinese medicine (TCM) and is officially documented in the Chinese Pharmacopeia with the name ‘Shi Chang Pu’. It belongs to the Araceae family and is used for the treatment of dementia, epilepsy, amnesia and insomnia. We resequenced complete chloroplast (cp) genome of A. tatarinowii from Fujian, China. The whole genome was 153,453 bp in length, consisting of a pair of inverted repeats (IR 25,795 bp), a large single-copy region (LSC 83,631 bp), and a small single-copy region (SSC 18,232 bp). The complete genome contained 132 genes, including 84 protein-coding genes, 38 tRNA, and 8 rRNA genes. The overall GC content of the whole genome was 38.7%. A maximum-likelihood phylogenetic analysis showed that A. tatarinowii is sister to A. tatarinowii which was collected in Yunnan, China. The complete chloroplast genome of A. tatarinowii will help improve and integrate the existing genome data of monocots and provide insights into the phylogenetic relationship among basal angiosperms, monocots and dicots.
