Abstract

Gynochthodes cochinchinensis previously known as Morinda cochinchinensis is considered as potential medicinal plant in family Rubiaceae. In this paper, the complete chloroplast genome of G. cochinchinensis was sequenced and characterized for the first time. The cp genome of G. cochinchinensis was 153,022 bp in length containing a large single copy region (83,799 bp), a small single copy region (17,591 bp), and a pair of inverted repeat regions (25,816 bp). It has a total of 131 genes, comprising of 86 protein-coding genes, eight rRNA genes, and 37 tRNA genes. Phylogenetic analysis revealed that Gynochthodes cochinchinensis together with Gynochthodes officinalis were closely related to genus Morinda.

Keywords: Gynocthodes cochinchinensis; Rubiaceae; complete chloroplast genome; phylogeny.
