Description
Summary: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.
