Complete chloroplast genome of Acer tegmentosum and phylogenetic analysis

The aim of the present study was to sequence and analyze the complete plastid genome (i.e. plastome) of Acer tegmentosum Maxim. The plastome of A. tegmentosum was 156,435 bp in length and included both large (86,265 bp) and small (18,102 bp) single-copy regions, which were separated by a pair of identical inverted repeats (26,034 bp). The plastome contained 77 unique protein-coding genes, 30 tRNA genes, and four rRNA genes. In addition, the gene order and organization of the A. tegmentosum plastome were consistent with those of plastomes from other members of the Sapindaceae, and the overall GC content of the plastome was 37.8%. A phylogenetic tree that was based on 76 protein-coding genes demonstrated a sister relationship within genus Acer.
