Abstract
In this study, we report the first complete chloroplast (cp) genome sequence of Salix wilsonii. The cp genome is 155,026 bp in length, exhibiting a typical quadripartite structure of a large single copy (LSC) region of 83,917 bp, a small single copy (SSC) region of 16,285 bp and a pair of inverted repeats (IRs) region of 27,412 bp. The overall base composition of the cp genome in asymmetric order is A: 32.09%, C: 17.94%, G: 18.65%, and T: 31.31%, and the AT content is 63.4%, whereas the proportions of AT contents in LSC, SSC, and IR regions are 66.53%, 68.99%, and 58.27%, respectively. Further, phylogenetic analysis of 46 species shows that S. wilsonii is evolutionarily closest to Sailx tetrasperma, and both of them belong to the genus Salix.
