The complete chloroplast genome of Calanthe arcuata, an endemic terrestrial orchid in China

Abstract

Calanthe arcuata is an endemic terrestrial orchid in China with high value of ornament and breeding. Here, we reported the first complete chloroplast genome of this plant in this research. The circular genome is 158,735 bp in length and includes large single-copy (LSC) region of 87,348 bp, small single-copy (SSC) region of 18,489 bp, and a pair of invert repeats (IR) regions of 26,449 bp. It contains 136 genes, including 88 protein-coding (PCG), 38 transfer RNA (tRNA), and eight ribosomal RNA (rRNA) gene. The phylogenetic analysis indicated that C. arcuata is the sister to C. davidii and C. triplicata.
