The complete chloroplast genome of <i>Goodyera yunnanensis</i> Schltr.

The family Orchidaceae is renowned for its extensive diversity. Within this family, the genus <i>Goodyera</i> R. Br. is classified under the subtribe Goodyerinae, comprising approximately 99 species. In this study, a species <i>Goodyera yunnanensis</i> Schltr., its plastid genome was characterized. The plastid genome of <i>G. yunnanensis</i> is 146,197 bp in size and exhibits a typical quadripartite structure with a pair of inverted repeat regions (IRs) of 25,611 bp, a large single-copy region (LSC) of 81,300 bp and a small single-copy region (SSC) of 13,675 bp. A total of 126 genes were identified, containing 80 protein-coding genes, 38 tRNA genes and 8 rRNA genes. The overall GC content is 37.2%, with corresponding values of 43.3%, 34.7% and 29.1% in IR, LSC and SSC regions, respectively. Forty-seven simple sequence repeats (SSRs) are found in <i>G. yunnanensis</i> plastome, and the frequency of mononucleotide repeats is significantly higher than other repeat types. Phylogenetic analysis indicates that <i>Goodyera</i> is resolved into four clades. <i>G. yunnanensis</i> belongs to the monophyletic clade A, and its phylogenetic position can be reasonably supported by morphological and molecular data.
