The complete chloroplast genome of Salix lindleyana (salicaceae), a plateau plant species

Abstract

Salix lindleyana Wallich ex Andersson 1851 is a species of genus Salix which mainly grows on mountains above 3000 m at sea level in Qinghai–Tibetan Plateau (including the Himalayas and Hengduan Mountains). To determine its phylogenetic position within Salix, we reconstructed S. lindleyana complete chloroplast (cp) genome sequence by de novo assembly using whole-genome sequencing data. The completed chloroplast genome was 155,304 bp, with a total GC content of 36.7%. It had a very typical tetrad structure, including a large single-copy (LSC) region of 84,539 bp, a small single-copy (SSC) region of 16,161 bp, and two inverted repeats (IR) regions of 27,302 bp. A total of 132 functional genes were distributed in the chloroplast genome, including 87 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Phylogenetic analysis showed that S. lindleyana was clustered with Salix dasyclados Wimmer 1849 and Salix variegata Franchet 1887. The complete chloroplast genome of S. lindleyana provides potential genetic resources for further phylogenetic studies.
