The complete plastome sequence of Carissa macrocarpa (Eckl.) A. DC. (Apocynaceae)

Abstract

In this study, we determined the complete plastome sequence of Carissa macrocarpa (Eckl.) A. DC. (Apocynaceae) (NCBI acc. no. KX364402). The gene order and structure of the C. macrocarpa plastome are similar to those of a typical angiosperm. The complete plastome is 155,297 bp in length, and consists of a large single-copy region of 85,586 bp and a small single-copy region of 18,131 bp, which are separated by two inverted repeats of 25,792 bp. The plastome contains 113 genes, of which 79 are protein-coding genes, 30 are tRNA genes and 4 are rRNA genes. Sixteen genes contained one intron and two genes have two introns. The average A-T content of the plastome is 62.0%. A total of 31 simple sequence repeat loci were identified within the genome. Phylogenetic analysis revealed that C. macrocarpa is a member of the paraphyletic subfamily Rauvolfioideae of Apocynaceae. The sister group relationship of C. macrocarpa to the Apocynoideae-Asclepiadoideae clade is supported by 100% bootstrap values.
