The complete chloroplast genome sequence of the Korean maple tree (Acer pseudosieboldianum (Pax) Kom.)

The complete chloroplast genome sequence of Acer pseudosieboldianum (Sapindaceae) was determined. The chloroplast genome of A. pseudosieboldianum is 157,053 bp in length with two inverted repeats (26,747 bp) between a large single-copy (85,391 bp) and a small single-copy (18,168 bp). The GC content was 37.8% and it was composed of 86 coding genes, eight rRNA genes, 37 tRNA genes, and two pseudogenes, rps2, and ycf1. Molecular phylogenetic analysis based on the plastid genome sequences strongly supported the hypothesis that A. pseudosieboldianum was embedded in the series Palmata of section Palmata. However, the phylogenetic positions of A. ukurunduense and A. buergerianum, which are a members of the series Penninervia of sections Palmata and Pentaphylla, respectively, were incongruent with the recent sectional classification system.
