The complete chloroplast genome of <i>Dioscorea tenuipes</i> Franch. &amp; Sav. and its phylogenetic analysis

Here, we present the first complete chloroplast genome of <i>D. tenuipes</i> (154,018 bp), which exhibits a typical quadripartite structure, including an LSC (83,966 bp), SSC (18,910 bp), and two IRs (25,571 bp each). A total of 133 genes were annotated, with 114 unique genes and 19 duplicated in the IRs. .Phylogenetic analyses based on complete chloroplast genomes of 13 <i>Stenophora</i> species strongly supported <i>D. tenuipes</i> as sister to <i>D. gracillima</i> (BS = 100%, PP = 1.0), challenging earlier studies that suggested a sister relationship with <i>D. tokoro</i> based on partial plastid sequences. Overall, this study provides a critical genomic resource for advancing research on the taxonomy, evolution, and medicinal breeding of <i>D. tenuipes</i>.
