The complete chloroplast genome sequence of Acer takesimense (Sapindaceae), an endemic to Ullenung Island of Korea

Abstract

The complete chloroplast (cp) genome sequence of Acer takesimense, a member of maple tree and an endemic species to Ulleung Island of Korea, was firstly analyzed in this study. It was formed a typical circular structure of 157,023 bp in length and composed of a large single copy region (85,371 bp) and a small single copy region (18,160 bp) which were separated by two inverted repeat regions (26,746 bp). Interestingly, rps2 gene was pseudogene due to two deletions of 5 bp. In the phylogenetic tree using chloroplast genome sequence, it was clear that the genus Acer, a monophyletic group, was sister to Dipteronia in the subfamily Hippocastanoideae and A. takesimense was a sister group of A. palmatum.
