is an extremely endangered species in the Qinghai-Tibet Plateau. Based on the second-generation high-throughput genome sequencing, we assembled the plastome of this species. The length of the total plastome is 152,324 bp with a typical quadripartite structure including a large single-copy region of 83,708 bp, a small single-copy region of 29,882 bp and two reverse repeat regions of 19,367 bp respectively. A total of 131 genes were annotated including 85 protein-coding genes (PCG), 36 tRNA genes, 8 rRNA genes and 2 pseudogenes. The constructed phylogenetic tree with other species of two tribes Senecioneae and Astereae based on plastomes suggests that has a close relationship with the Astereae, but diverged early from this tribe.
是青藏高原的一种极度濒危物种。基于二代高通量基因组测序，我们组装了该物种的质体基因组。整个质体基因组长度为152,324 bp，具有典型的四分体结构，包括一个83,708 bp的大单拷贝区域、一个29,882 bp的小单拷贝区域和两个分别为19,367 bp的反向重复区域。共注释了131个基因，包括85个蛋白质编码基因（PCG）、36个tRNA基因、8个rRNA基因和2个假基因。基于质体基因组构建的与千里光族和紫菀族其他物种的系统发育树表明， 与紫菀族关系密切，但在该族中分化较早。
