Characterization of the complete chloroplast genome of Salix koreensis Anderss (Salicaceae) 1868

Abstract

Salix koreensis Anderss 1868 is a grey-barked, arboreal willow with high economic value. This study reports the S. koreensis chloroplast (cp) genome. A phylogenetic tree has also been constructed to illustrate the relationship between S. koreensis and 25 other species within the Salicaceae family. The total length of the chloroplast genome is 155,865 bp, which can be divided into four parts: one large single-copy (LSC) length of 84,477 bp, one small single-copy (SSC) length of 16,316 bp, and two inverted repeat (IRA and IRB) lengths of 27,446 bp. The cp genome of S. koreensis is composed of 133 genes, including 86 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. According to the phylogenetic tree, S. koreensis and S. chienii are closely related.
