Abstract

Geodorum eulophioides Schltr., is a critically Endangered orchid (IUCN). In this study, we report the first complete chloroplast (cp) genome of G. eulophioides to provide the underlying information for genetic breeding and conservation studies of this species. The cp genome sequence of G. eulophioides is 149,466 bp in length, which contains one large single-copy region (LSC, 85,436 bp), one small single-copy region (SSC, 14,086 bp), and two inverted repeat regions (IRs, 24,972 bp). The cp genome encoded 177 genes, of which 106 were unique genes (78 protein-coding genes, 24 tRNAs, and 4 rRNAs). Phylogenetic analysis showed that G. eulophioides is closely related to the genera Eulophia.
