The complete chloroplast genome of two traditional medical plants: Asparagus cochinchinensis (Lour.) Merr. and Asparagus dauricus Fisch. ex Link

Abstract

Asparagus cochinchinensis (Lour.) Merr. and Asparagus dauricus Fisch. ex Link are two traditional medical plants with therapeutic effects, distributed in mountainous regions of China. In the current study, the complete chloroplast (cp) genomes of A. cochinchinensis and A. dauricus were sequenced on the Illumina Hiseq 2500, and obtained with a length of 157,095 bp and 156,918 bp, respectively, both containing a large single-copy region and a small single-copy region separated by a pair of inverted repeat regions. The cp genome of A. cochinchinensis has 132 annotated genes including 86 protein-coding genes, 38 tRNA, and eight rRNA genes. A. dauricus has 112 annotated genes containing 78 protein genes, 30 tRNA, and four rRNA genes. The maximum-likelihood tree was reconstructed with 17 species, indicating that A. cochinchinensis is a sister group to the clade including A. officinalis to A. racemosa. This clade includes five species of Asparagus.
