The complete chloroplast genome of Angelonia angustifolia Benth. (Plantaginaceae), an ornamental and medicinal plant

In this study, we assembled and characterized the complete chloroplast (cp) genome of Angelonia angustifolia Benth., 1846, a herbaceous and perennial plant, native to Latin America. It is an ornamental and medicinal plant that showed bright prospects for application. The cp genome of A. angustifolia has a typical conserved quadripartite structure of 154,316 bp in total length. The genome includes a large single-copy (LSC) region (84,110 bp), a small single-copy (SSC) region (15,950 bp), and a pair of inverted repeat (IR) regions (27,128 bp). The cp genome contains 130 genes comprising 85 protein-coding, 37 tRNA, and 8 rRNA genes. Phylogenetic analysis indicates that A. angustifolia is closely related to Bacopa monnieri, Scoparia dulcis, and Limnophila sessiliflora in the Plantaginaceae. Taken together, the complete cp genomes of A. angustifolia provided significant insights and important information for molecular biology, evolution, and taxonomy in the genus Angelonia.
