Abstract:
Polyspora axillaris (Roxb. ex Ker Gawl.) Sweet 1825, is a shrub or tree that is about 9 meters tall in the Theaceae family, mainly distributed in China and Vietnam, and it is widely used as a green tree species in many regions owing to its rapid growth and good adaptability. It is rich in various beneficial extracts for humans, but there are limited studies on it. In this study, we sequenced and annotated the complete plastome of P. axillaris. The chloroplast genome length of P. axillaris is 156,770 bp, with a total of 132 genes, including 37 tRNA genes, 8 rRNA genes and 87 protein-coding genes. The complete chloroplast genome of P. axillaris contains two Inverted Repeats (IRs) of 26,077 bp, a Large Single-Copy (LSC) region of 86,286 bp and a Small Single-Copy (SSC) region of 18,330 bp. The overall G/C content in the chloroplast is 37.3%. Phylogenetic inference shows that P. axillaris formed a sister relationship with P. hainanensis, along with 10 Theaceae species. The research result of P. axillaris will contribute to the genetic preservation of the species and the phylogenetic study of Polyspora.
摘要:
腋下多孢子菌(Roxb。前KerGawl.)Sweet1825,是一种灌木或树木,在茶科中高约9米,主要分布在中国和越南,由于其生长迅速和良好的适应性,在许多地区被广泛用作绿色树种。它富含各种对人类有益的提取物,但是对它的研究有限。在这项研究中,我们测序并注释了腋下假单胞菌的完整质体。腋下假单胞菌叶绿体基因组长度为156,770bp,共有132个基因,包括37个tRNA基因,8个rRNA基因和87个蛋白质编码基因。腋下假单胞菌的完整叶绿体基因组包含两个26,077bp的反向重复序列(IRs),86,286bp的大型单拷贝(LSC)区和18,330bp的小型单拷贝(SSC)区。叶绿体中的总G/C含量为37.3%。系统发育推断表明,腋下假单胞菌与海南假单胞菌形成姐妹关系,以及10种山羊科物种。该研究结果将有助于该物种的遗传保护和多孢菌的系统发育研究。
