The complete chloroplast genome sequence of an economic plant Salix wilsonii

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.
