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 . 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 and were closely related. Overall, this study provided a wealth of information for a follow-up phylogenetic and evolutionary study of the Gentianales.
萝摩科植物(茜草科),通常称为诺丽,是一种药用植物,常被用作植物性膳食补充剂。本研究首次报道并表征了该植物的完整叶绿体基因组。我们发现它包含153,113 bp,GC含量为38.05%,由两个反向重复区域(IRs,25,588 bp)、一个大单拷贝区域(LSC,83,974 bp)和一个小单拷贝(SSC,17,963 bp)区域组成。共注释了125个基因,包括84个蛋白质编码基因、33个转运RNA(tRNA)基因和8个核糖体RNA(rRNA)基因。系统发育分析表明该植物与其他某植物(原文此处未明确)关系密切。总体而言,本研究为龙胆目后续的系统发育和进化研究提供了丰富的信息。
