Characterization of the complete chloroplast genome of Salix gordejevii (Salicaceae)

Abstract

Salix gordejevii is an endemic species in northern China. The analysis of the complete chloroplast genome of S. gordejevii can offer a referential basis for identifying and utilizing Salix germplasm resources. In this study, we obtained chloroplast DNA from S. gordejevii and characterized it. The complete chloroplast genome of S. gordejevii is 155,491 bp in length, comprising a pair of inverted repeats (IR, 27,408 bp), a large single-copy region (LSC, 84,367 bp), and a small single-copy region (SSC, 16,309 bp). We annotated 117 genes in total, including 80 protein-coding genes, 32 tRNA genes, four rRNA genes, and one pseudogene (ycf1). A maximum-likelihood phylogenetic tree was built with MEGA-X and showed that the chloroplast of S. gordejevii has the closest relationship with that of S. magnifica compared to the other reported Salix genomes.
