Complete chloroplast genome of <i>Cephalanthera erecta</i> (Thunb.) Blume (Orchidaceae) and its phylogenetic analysis

We report the chloroplast (cp) genome of <i>Cephalanthera erecta</i> (Thunb.) Blume, a terrestrial orchid endemic to East Asia, to clarify its phylogenetic relationship. The 162,011 bp genome has a typical quadripartite structure: a large single-copy (LSC: 88,944 bp), a small single-copy (SSC: 19,177 bp), and a pair of inverted repeats (IRs: 26,945 bp). Annotation identified 135 genes, including 88 mRNAs, 38 tRNAs, eight rRNAs, and one pseudogene. Phylogenetic analysis places <i>C. erecta</i> in a well-supported clade with <i>C. longibracteata</i>, <i>C. falcata</i>, and <i>C. nanchuanica</i>, confirming their close evolutionary relationship. This findings provide genomic resources, clarifies its phylogenetic position, aiding conservation and evolutionary studies of East Asian orchids.
