is a dwarf species of the genus Salix which distribute in harsh arctic environment. In this study, we sequenced and assembled whole mitochondrial genome of for the first time. The complete mitochondrial genome sequence of this species is a circular molecule of 562920 bp in size, encoding 23 CDS, 21 tRNA genes, and 3 rRNA genes. Mitogenome based phylogenetic tree showed that clustered in the robust clade consist of all species sampled in this study. The complete mitochondrial genome of adds new data into the whole mitochondrial genome of , which is still scarce so far, and we anticipate the accumulation of mitogenome of will facilitate phylogenetic study for this systematic difficult genus.
是柳属的一种矮生物种，分布于恶劣的北极环境中。在本研究中，我们首次对其全线粒体基因组进行了测序和组装。该物种的完整线粒体基因组序列是一个大小为562920 bp的环状分子，编码23个编码序列、21个tRNA基因和3个rRNA基因。基于线粒体基因组的系统发育树显示，该物种聚集在由本研究中采样的所有物种组成的稳健分支中。该物种的完整线粒体基因组为柳属全线粒体基因组增添了新数据，到目前为止该属的数据仍然稀缺，我们预计柳属线粒体基因组的积累将有助于对这个系统分类困难的属进行系统发育研究。
