The complete chloroplast genome sequence of Anoectochilus emeiensis.

The complete chloroplast (cp) genome sequence of Anoectochilus emeiensis, an extremely endangered medical plant with important economic value, was determined and characterized. The genome size was 152 650 bp, containing a pair of inverted repeats (IRs) (26 319 bp) which were separated by a large single copy (LSC) (82 670 bp) and a small single copy (SSC) (17 342 bp). The cpDNA of A. emeiensis contained 113 unique genes, including 79 protein coding genes, 30 tRNA genes and 4 rRNA genes. Among them, 18 genes contained one or two introns. The overall AT content of the genome was 63.1%.
