The complete chloroplast genome of Agapanthus praecox (Agapanthaceae), an ornamental and medicinal plant

Agapanthus praecox is a monocotyledonous, herbaceous, and perennial plant, which has been used as an ornamental and medicinal plant. Here, we assembled and characterized the complete chloroplast (cp) genome of A. praecox by de novo high throughput sequencing. The results revealed that the cp genome of A. praecox was 157,038 bp in total length, including a large single-copy (LSC) region of 85,195 bp, a small single-copy (SSC) region of 18,113 bp, and two invert repeats (IR) regions of 26,865 bp. The total plastid genome of A. praecox included 132 genes comprising 86 protein-coding genes, 38 tRNA genes, and eight rRNA genes. The phylogenetic analysis was conducted based on the complete cp genomes of 17 species and it indicated that A. praecox is closely related to A. coddi in Agapanthaceae family.
