This study was the first report about complete chloroplast genome of (Asteraceae: Pertyeae), a critically shurby plant. The complete chloroplast genome of was 153,379 bp in length and a typical circular structure, which comprises a pair of inverted repeat (IR) region of 25,191 bp divided by a large single-copy (LSC) region of 84,535 bp and a small single-copy (SSC) region of 18,462 bp. The general GC content was 37.6% in the whole sequence, whereas corresponding values of 35.6%, 31.2%, and 43.1% in the LSC, SSC, and IR regions, respectively. The whole genome contained 113 unique genes, including 79 protein-coding genes, 4 ribosomal RNA genes, and 30 tRNA genes. The phylogenetic hypotheses obtained based on the analyses of 21 cp genomes indicates was supported as a sister group to the tribe Carduoideae.
本研究是关于一种极度濒危的灌木植物（菊科：佩尔泰族）叶绿体全基因组的首次报道。该植物的叶绿体全基因组长度为153,379 bp，呈典型的环状结构，由一对25,191 bp的反向重复（IR）区域、一个84,535 bp的大单拷贝（LSC）区域和一个18,462 bp的小单拷贝（SSC）区域组成。整个序列的总体GC含量为37.6%，而LSC、SSC和IR区域的相应值分别为35.6%、31.2%和43.1%。全基因组包含113个独特基因，包括79个蛋白质编码基因、4个核糖体RNA基因和30个tRNA基因。基于对21个叶绿体基因组的分析得到的系统发育假说表明，该植物被支持为刺头菊族的姐妹群。
