The complete chloroplast genome sequence of wild service tree Sorbus torminalis (L.) Crantz

Abstract

Sorbus torminalis is widely distributed tree species across Europe which shows interesting features from the genetic point of view and has high ecological values. Based on the whole genomic DNA we have assembled the complete 160,390 bp circular chloroplast genome of the species. The nucleotide share: 31.35% A, 18.61% C, 17.87% G, 32.12% T and 36.48% GC content is similar to those found in the Pyrus and Malus species. The genome is a standard quadripartite structure build from four subunits: large (88,029 bp) and small (19,547 bp) single copy unit and two inverted repeats (26,407 bp each). The genome contains 127 genes including: 83 protein-coding genes (77 unique), 36 tRNA genes (29 unique), and 8 rRNA genes (4 unique). Phylogenetic position of S. torminalis based on the whole chloroplast genome indicated that the species is phylogenetically closer to genus Malus than Pyrus.
