Abstract

Ephedra monosperma is an important medicinal plant of Ephedra (Ephedraceae). The complete chloroplast genome of E. monosperma was assembled from Illumina pair-end sequence reads. The whole chloroplast (cp) genome is 109,548 bp in length and presents a quadripartite structure consisting of two copies of inverted repeat (IR) regions (20,398) separated by a large single copy (LSC) region (60,674 bp) and a small single copy (SSC) region (8078 bp). The cp genome of E. monosperma encodes a total of 118 genes, including 73 protein-coding genes, 37 tRNA genes and 8 rRNA genes. The overall GC content of E. monosperma cp genome is 36.6%. A maximum likelihood (ML) phylogenetic analysis revealed that E. monosperma was close to Ephedra equisetina. The ML tree also showed Ephedraceae appeared more closely related to Gnetaceae than to the other families in Gymnospermae.
