The complete chloroplast genome of a shrub species, Smilax glabra (Smilacaceae) from Guangdong, China.

Smilax glabra is a perennial woody scandent shrub, of which the dried aerial tuber has been used as Chinese medicine. Here, we sequenced S. glabra and assembled its complete chloroplast (cp) genome. The genome is 157,889 bp in length and has a typical quadripartite structure. We annotated 131 genes, of which 84 were protein-coding genes, 37 were tRNAs and 8 were rRNA genes. Phylogenetic analysis of this genome with 26 representatives Liliales fully resolved S. glabra in a clade with S. china. The phylogenetic tree we constructed is largely consistent with recently published phylogenetic trees using both complete chloroplast genomes and marker gene sequences.
