Characterization of the complete chloroplast genome of ornamental plant, Bougainvillea peruviana (Nyctaginaceae).

Bougainvillea peruviana is a widely domesticated ornamental plant species. However, studies on B. peruviana are limited. In this study, we reported the complete chloroplast (cp) genome of B. peruviana. The cp genome is 154,465 bp in length, containing a large single-copy (LSC) of 85,563 bp and a small single-copy (SSC) of 18,050 bp, which are separated by a pair of inverted repeats (IRs) of 25,426 bp, each. A total of 132 genes, including 86 protein-coding genes, 38 tRNA genes, and eight rRNA genes, were predicted. The overall GC content for the cp genome is 36.5%. The maximum-likelihood tree constructed based on cp genome sequences showed that B. peruviana is placed under Nyctaginaceae and is diverged before Bougainvillea glabra and Bougainvillea spectabilis under strong bootstrap support.
