Abstract:
Olea dioica Roxb, 1820 is a very important ethnomedicinal tree because of its medicinal properties and it belongs to the Oleaceae family. It is mainly distributed in evergreen and semi-evergreen forests. However, the chloroplast genome of O. dioica has not yet been reported. In this study, the chloroplast genome sequence of O. dioica was sequenced using next-generation sequencing technologies. The complete chloroplast genome of O. dioica was 155,138 bp in length (GenBank accession no. PP048999), comprising a large single-copy (LSC) region of 86,048 bp, a small single-copy (SSC) region of 17,816 bp, and two inverted repeat (IR) regions 25,637 bp each. The overall GC content was 37.8%. The complete chloroplast genome of O. dioica contains 131 complete genes, which are 88 protein-coding genes, 35 transfer RNA genes, and eight ribosomal RNA genes. A maximum-likelihood (ML) tree of O. dioica and 14 other species in the family Oleaceae suggested that O. dioica showed a close relationship with Olea brachiata.
