Complete chloroplast genome sequence of Acer sutchuenense subsp. tienchuanenge (Sapindaceae)

Abstract

Acer sutchuenense subsp. tienchuanenge (Sapindaceae: Acer) is an endangered deciduous arbor species and endemic to China. Being obtained by using genome Illumina pair-end sequencing data, the complete chloroplast genome of A. sutchuenense subsp. tienchuanenge had a typical quadripartite structure, with 156,063 bp long, including a large single-copy (LSC) region of 85,772 bp, a small single-copy (SSC) region of 18,117 bp, and a pair of inverted repeats (IRs) (each 26,087 bp in length). A total of 136 genes were annotated, of which 113 are unique genes, including 30 tRNAs, 4 rRNAs, and 79 protein-coding genes. The overall GC content was 37.9%. The phylogenetic analysis suggested that A. sutchuenense subsp. tienchuanenge was the most closely related to A. griseum and A. triflorum. The complete chloroplast genome of A. sutchuenense subsp. tienchuanenge is valuable for assessment and conservation of genetic resources and further for phylogenetic study of Acer L.
