摘要

本研究首次获得了柽柳叶绿体基因组（154,018 bp），具有典型的四分体结构，包括LSC （83,966 bp）、SSC （18,910 bp）和两个IRs（各25,571 bp）。共有133个基因被注释，其中114个是唯一基因，19个在IRs中重复。基于13种窄翅属植物叶绿体全基因组的系统发育分析有力地支持了D. tenupes与D. gracillima的亲缘关系（BS = 100%, PP = 1.0），挑战了早先基于部分质体序列推测其与D. tokoro亲缘关系的研究。总之，本研究为推进龙舌兰的分类、进化和药用育种研究提供了重要的基因组资源。

The complete chloroplast genome of Dioscorea tenuipes Franch. & Sav. and its phylogenetic analysis.

Here, we present the first complete chloroplast genome of D. tenuipes (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 Stenophora species strongly supported D. tenuipes as sister to D. gracillima (BS = 100%, PP = 1.0), challenging earlier studies that suggested a sister relationship with D. tokoro based on partial plastid sequences. Overall, this study provides a critical genomic resource for advancing research on the taxonomy, evolution, and medicinal breeding of D. tenuipes.
