Complete chloroplast genome of the endangered Corybas taliensis (Orchidaceae), a plant species with extremely small populations endemic to China

Abstract

Corybas taliensis is an endangered terrestrial orchid, endemic to China. In this study, we assembled the complete chloroplast (cp) genome using Illumina pair-end sequencing data. The whole cp genome is 131,393 bp in length with 38.21% of GC content. It encodes 121 genes, including 38 tRNA genes, 8 rRNA genes, and 75 protein-coding genes. The phylogenetic tree based on 13 cp genomes of Orchidoideae suggested that C. taliensis is closely related to Rhizanthella gardneri. This study will pave the way to understand the genomic information and conservation of this endangered endemic orchid species.
