The complete chloroplast genome of an endangered species Apostasia ramifera (Orchidaceae).

ABSTRACT: Apostasia ramifera S. C. Chen & K. Y. Lang 1986 is a Chinese endemic and endangered orchid. Here, we report the complete chloroplast (cp) genome sequence and the cp genome features of A. ramifera. The cp genome was 157,518 bp in length with a typical quadripartite structure, which was comprised of one large single-copy region (LSC, 86,353 bp) and one small single-copy region (SSC, 16,445 bp) separated by two inverted repeat regions (IRs, 27,360 bp). The cp genome encoded 133 genes, which included 87 protein-coding genes, 38 tRNAs and eight rRNAs. The average GC content of the genome is 35.8%. The phylogenetic analysis showed that A. ramifera was sister with A. wallichii and then nested in the other Apostasia species.
