Two complete chloroplast genomes of an endangered orchid species, Pelatantheria scolopendrifolia (Orchidaceae), in Korea

Abstract

We determined the complete chloroplast genome sequence of two individuals of Pelatantheria scolopendrifolia, an endangered orchid species in Korea. The total chloroplast genome size of Mokpo (MG752972) and Naju (MG752973) population was 146,971 bp and 146,848 bp, respectively. The chloroplast genome contained 106 genes, including 72 protein-coding genes, 30 tRNA genes, and four rRNA genes. Variation in gene contents and structures was not found between two individuals. We found truncated or deleted ndh genes in P. scolopendrifolia. Phylogenetic analysis, based on the whole chloroplast genome sequences of 25 species of Orchidaceae, showed that P. scolopendrifolia was most closely related to Gastrochilus fuscopunctatus.
