Sequencing and characterization of the complete chloroplast genome of Sorbaria arborea (Rosaceae)

Sorbaria arborea is a species which is endemic to China. We utilized next-generation Illumina sequencing technology to sequence and assemble its chloroplast genome. The 160,137 bp genome contained four main sections, including a pair of inverted repeat regions which were 26,332 bp in length, and a small single-copy region was 19,418 bp, as well as a large single-copy region, which was 88,055 bp. The genome had a GC content of 36.1% and contained 113 unique genes, including 4 rRNAs, 30 tRNAs, and 79 protein-coding genes. The phylogenetic relationship of 25 Rosaceae species was constructed based on their chloroplast genome sequences, which supported a close relationship between S. arborea and Amygdaloideae. This newly sequenced plastid genome provides useful information for assessing the genetic diversity and phylogenetic position of S. arborea.
