The plastome sequence of Ulleung Rowan, Sorbus ulleungensis (Rosaceae), a new endemic species on Ulleung Island, Korea

Abstract

The complete chloroplast genome sequence of Sorbus ulleungensis, a recently described endemic species to Ulleung Island of Korea, was determined. The genome size was 159,632 bp in length with 36.5% GC content. It included a pair of inverted repeats (IRa and IRb) of 26,402 bp, which were separated by small single copy (SSC: 18,824 bp) and large single copy (LSC: 88,003 bp) regions. The cp genome contained 111 genes, including 78 protein coding genes, 29 tRNA genes, and four rRNA genes. Phylogenetic analysis of the combined 78 protein coding genes and four rRNA genes showed that S. ulleungensis was most closely related to Pyrus pyrifolia.
