摘要

玉兰Á.J。psamurez & E.Rea 2023是厄瓜多尔安第斯山脉西南部的一种新发现的地方性濒危物种。其质体基因组的测序和鉴定将有助于阐明其与其他新热带白玉兰的亲缘关系。物种。质体基因组全长159,782 bp，包括131个基因、86个蛋白质编码基因（PCGs）、37个转移RNA （tRNA）和8个核糖体RNA （rRNA）区域。系统发育分析证实了该物种在Talauma （Juss.）剖面的分类归属。Baill 1866及其与1996年来自哥伦比亚的Magnolia gilbertoi (Lozano) Govaerts的密切关系，属于同一部分。然而，系统发育关系显示出较低的自举支持。

Characterization of the complete plastid genome sequence of Magnolia buenaventurensis Á.J. Pérez & E. Rea (Magnoliaceae), a newly described species endemic to the Ecuadorian Andes.

Magnolia buenaventurensis Á.J.Pérez & E.Rea 2023 is a newly described, endemic, and endangered species of the southwest Ecuadorian Andes mountains. Sequencing and characterizing its plastid genome will help clarify its relationship to other Neotropical Magnolia L. 1753. species. The plastid genome is 159,782 bp in length and includes 131 genes, 86 protein-coding genes (PCGs), 37 transfer RNAs (tRNA), and eight ribosomal RNA (rRNA) regions. Phylogenetic analysis confirms the species' taxonomic classification in the section Talauma (Juss.) Baill 1866 and its close relationship to Magnolia gilbertoi (Lozano) Govaerts 1996 from Colombia, which belongs to the same section. However, the phylogenetic relationship shows low bootstrap support.
