Characterization of the complete chloroplast genome of Amsonia elliptica (Apocynaceae)

Abstract

Amsonia elliptica (Apocynaceae), endangered species in Korea, is a perennial herb that is economically important as traditional medicine and used as ornamentals. Natural populations of this species are facing extinction due to small population size and isolated distribution. Here, we report the complete chloroplast (cp) genome of A. elliptica using Illumina HiSeq sequencing and its phylogenetic position in subfamily Rauvolfioideae based on 20 Apocynaceae cp genomes. The cp genome of A. elliptica was 154,242 bp in length with a pair of inverted repeats of 25,711 bp, separated by large single-copy and small single-copy regions of 85,382 bp and 17,438 bp, respectively. Our phylogenomic analyses revealed that A. elliptica was closely related to Rhazya stricta in Rauvolfioideae (Apocynaceae).
