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

Abstract

The complete chloroplast genome sequence of Salix variegata, a native shrub willow species in the south of China, is reported. The plastome is 155,743 bp in length, with one large single copy region of 84,950 bp, one small single copy region of 16,219 bp, and two inverted repeat (IR) regions of 27,287 bp. It contains 130 genes, including 83 protein-coding genes, eight ribosomal RNA, and 38 transfer RNA. Phylogenetic tree shows that this species is a sister to S. purpurea. The published plastome within Salix provides significant insight for elucidating the phylogenetic relationship of taxa within Salicaceae.
