ABSTRACT
The complete chloroplast genome of Sorbus hupehensis var. paucijuga was sequenced with Illumina HiSeq 2000 platform. It was a typical quadruple structure as other plants of Sorbus with 160,050 bp in length, including a large single-copy (LSC 87,905 bp) region and a small single-copy (SSC 19,325 bp) which were separated by a pair of inverted repeats (IRa, b 26,410 bp) region. The overall GC content is 36.5%. A total of 130 genes was annotated which contained 85 protein-coding genes including the Trans splicing gene of rps12, 37 tRNA genes, and 8 rRNA genes. ML phylogenetic analysis compared with 7 expressed chloroplast genomes of Rosaceae revealed that S. hupehensis var. paucijuga was a sister to other Sorbus species. Six species of Sorbus were divided into two groups, the species of group one is distributed in Asia and the species of group two distributed in Europe. Among group one, S. hupehensis var. paucijuga had the closest genetic relationship with S. ulleungensis which is a New Endemic Species on Ulleung Island of Korea, and followed by S. setschwanensis which is only distributed in Sichuan and Guizhou of China. Sorbus hupehensis var. paucijuga has a relatively close relationship with the other three species of Sorbus in the group two. And, it has a relatively distant from other genera of Prunus mongolica and Rosa rugosa.
