The complete chloroplast genome and phylogenetic analysis of Salix triandra from China

Abstract

Salix triandra is a great willow for bees and an excellent choice for living willow structures. In this study, we assembled and annotated the complete chloroplast (cp) genome sequence of S. triandra. The whole cp genome is 155,821 base-pairs (bp) in size, which comprises one small single copy (SSC) region of 16,223 bp and one large single copy (LSC) region of 84,532 bp separated by a pair of inverted repeats (IRs) of 27,533 bp. There are 131 genes, including 86 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Phylogenetic analysis with the Neighbour-joining method indicates that S. triandra is closely related to S. tetrasperma. The complete cp genome will facilitate the biological studies in the order Malpighiales in future.
