Abstract：
Nostolachma jenkinsii (Hook.f.) Deb & J.Lahiri, a member of the Rubiaceae family, is an endangered wild plant species with potential economic value. In this research, the complete chloroplast genome of N. jenkinsii was sequenced to gain insight into its genome feature and better understand the phylogenetic relationships among the Rubiaceae species. The chloroplast genome, with a total length of 155,036 bp, comprises two inverted repeats (IR) regions spanning 25,692 bp each, a large single-copy (LSC) region measuring 85,437 bp, and a short single-copy (SSC) region measuring 18,215 bp. There is an overall 37% GC content in the chloroplast genome. By annotation analysis,. 54 tRNA genes, 10 rRNA genes, and 107 protein-coding genes were all annotated in N. jenkinsii. Furthermore, we applied phylogenetic analysis that revealed a close relationship between N. jenkinsii, D. fruticosa and D. dubia, placing them together within the Rubiaceae family.
摘要：
Nostolachmajenkinsii(Hook.f.)Deb&J.Lahiri，茜草科的一员,是一种具有潜在经济价值的濒危野生植物。在这项研究中,对金金氏奈瑟菌的完整叶绿体基因组进行了测序，以深入了解其基因组特征，并更好地了解茜草科物种之间的系统发育关系。叶绿体基因组，总长度为155,036bp，包含两个跨越25,692bp的反向重复(IR)区域，一个大的单拷贝(LSC)区域，测量85,437bp，和一个18,215bp的短单拷贝（SSC）区域。叶绿体基因组中总的GC含量为37%。通过注释分析，.54个tRNA基因，10个rRNA基因，和107个蛋白质编码基因都被注释在N.jenkinsii中。此外，我们应用了系统发育分析，揭示了金氏奈瑟菌之间的密切关系，D.fruticosa和D.dubia,将它们放在茜草科内。
