Abstract

Salix polaris 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 S. polaris 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 Salix polaris clustered in the robust clade consist of all Salix species sampled in this study. The complete mitochondrial genome of Salix polaris adds new data into the whole mitochondrial genome of Salix, which is still scarce so far, and we anticipate the accumulation of mitogenome of Salix will facilitate phylogenetic study for this systematic difficult genus.

北极环境中的物种柳柳的线粒体完整基因组

摘要

柳宝来是柳属的矮种,其中分布在恶劣的北极环境。在这项研究中,我们第一次测序和组装北极星链球菌的整个线粒体基因组。该物种的完整线粒体基因组序列为562920 bp的环状分子,编码23个CDS,21个tRNA基因和3个rRNA基因。基于Mitogenome的系统发育树显示,在稳固进化枝中聚集的北极包括本研究中采样的所有柳属物种。的线粒体全基因组柳宝来增加了新的数据到整个线粒体基因组沙柳,这仍然是稀缺的,到目前为止,我们预计线粒体基因的积累将有助于对该系统困难属的系统发育研究。
