The complete chloroplast genome of Morinda citrifolia (noni)

Abstract

Morinda citrifolia L. (Rubiaceae), commonly called noni, is a medicinal plant that is often used as botanical dietary supplement. This study is the first to report and characterize the complete chloroplast genome of M. citrifolia. We found that it contains 153,113 bp with a GC content of 38.05%, consisting of two inverted repeat regions (IRs, 25,588 bp), a large single-copy region (LSC, 83,974 bp), and a small single copy (SSC, 17,963 bp) region. One hundred and twenty-five genes were annotated, including 84 protein-coding genes, 33 transfer RNA (tRNA) genes, and 8 ribosomal RNA (rRNA) genes. Phylogenetic analysis showed that M. citrifolia and Gynochthodes officinalis were closely related. Overall, this study provided a wealth of information for a follow-up phylogenetic and evolutionary study of the Gentianales.
