The complete chloroplast genome of sweet olive (Osmanthus fragrans Lour.)

Abstract

Osmanthus fragrans is valued for its beauty and fragrance. Here, we characterized the complete chloroplast (cp) genome of O. fragrans using next generation sequencing. The circular complete cp genome of O. fragrans is 155,896 bp in length, containing a large single-copy (LSC) region of 86, 521 bp, and a small single-copy (SSC) region of 20943 bp. It comprises 124 genes, including eight rRNA genes, 29 tRNAs genes, and 87 protein-coding genes. The GC content of O. fragrans cp genome is 37.8%. The phylogenetic analysis suggests that O. fragrans is a sister species to Abeliophyllum distichum and Hesperelaea palmeri in Oleaceae.
