The complete chloroplast genome sequence of Amentotaxus argotaenia (Taxaceae).

The complete chloroplast genome sequence of Amentotaxus argotaenia was determined in this study. The genome is 136 657 bp in length and lacks one inverted repeat region. The overall GC content of the genome is 35.85% (protein-coding genes, 36.90%; tRNA genes, 53.31%; rRNA genes, 52.99%; introns, 36.10%; intergenic spacers, 31.03%). The A. argotaenia chloroplast genome contains 118 unique genes, including 83 protein-coding genes, 31 tRNA genes, and four rRNA genes. Ten protein-coding genes and six tRNA genes have one intron, while ycf3 contains two. The coding regions occupy 60.27% of the genome length and the gene density is estimated to be 0.88 genes/kb. A maximum likelihood phylogenetic analysis suggested that Amentotaxus is sister to Taxus within the Taxaceae family.
