First record of the complete chloroplast genome of Syneilesis aconitifolia (Asteraceae).

Syneilesis aconitifolia is an herbaceous perennial of the Asteraceae family native to forests in China, Korea, Japan, and eastern Russia. In Korea, the young leaves of the plant are edible and the extract is known to have antitumor effects. The length of the complete plastome was found to be 150,773 bp, including 130 genes, consisting of 85 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The assembled plastome showed typical structure and gene content of the angiosperm plastome, which includes two inverted repeats (IR) regions of 24839 bp, a large single copy (LSC) region of 82911 bp, and a small single-copy (SSC) region of 18184 bp. The total G/C content in the S. aconitifolia plastome was 37.5%. The maximum likelihood (ML) phylogenetic tree strongly supports that S. aconitifolia is closely related to the hosts of Ligularia fischeri . This study reports the first complete chloroplast genome of the genus Syneilesis and will contribute to the phylogenetics of the family Asteraceae.
