The grape genus (Vitis L.) is of great agronomic importance and represents an economically valuable resource. Researchers have explored the phylogenetic relationships of subgenus Vitis for decades. However, the evolutionary patterns of many morphological characters of subgenus Vitis have not yet been explored in the context of a robust phylogenetic framework. Within the East Asian clade, V. bryoniifolia and its closely related taxa form the V. bryoniifolia clade, which is taxonomically complex. The phylogenetic relationships and species delimitation within this clade remain poorly resolved, due to the limited sampling in prior studies. We tested morphological trait evolution based on ancestral character state reconstruction using a phylogenomic framework. With 89 accessions from the East Asian subgenus Vitis sampled, a robust phylogenetic relationship of the V. bryoniifolia clade is reconstructed using the restriction-site associated DNA sequencing (RAD-seq) data, which support the monophyly of most taxa of the V. bryoniifolia clade. Ancestral character state reconstructions suggest that the weak climbing ability and simplified tendrils of Vitis each evolved multiple times. This study provides a reliable phylogenomic framework for the V. bryoniifolia clade. Coupled with morphological analyses, we discuss the taxonomic status of some taxa in the V. bryoniifolia clade and untangle a taxonomic dilemma in the grape genus.

使用系统植物学框架测试葡萄的形态特征演变并评估种属的界定。

葡萄属（Vitis L.）具有重要的农艺学意义，是一种经济上有价值的资源。研究人员已经探索了葡萄亚属的系统发育关系数十年。然而，尚未在稳健的系统发育框架的背景下探索葡萄属的许多形态特征的进化模式。在东亚进化枝中，V。bryoniifolia进化枝及其密切相关的分类单元形成了V. bryoniifolia进化枝，这在分类学上很复杂。由于先前研究中的采样有限，该进化枝内的系统发育关系和物种划分仍然很难解决。我们使用系统进化学的框架，基于祖先特征状态重构测试了形态特征进化。从东亚亚种（Vitis）的89个种质中取样，利用限制位点相关的DNA测序（RAD-seq）数据，重建了粗叶葡萄球菌进化枝的稳固的系统发育关系，该数据支持了大部分的细叶葡萄球菌进化枝的单系。祖先的性格状态重建表明，葡萄的弱爬能力和简化的卷须都进化了多次。这项研究为V.bryoniifolia进化枝提供了可靠的系统生物学框架。结合形态分析，我们讨论了V. bryoniifolia进化枝中某些分类单元的分类状态，并解开了葡萄属的分类分类难题。祖先特征状态的重建表明，葡萄的弱爬能力和简化的卷须都进化了多次。这项研究为V.bryoniifolia进化枝提供了可靠的系统生物学框架。结合形态分析，我们讨论了V. bryoniifolia进化枝中某些分类单元的分类状态，并解开了葡萄属的分类分类难题。祖先的性格状态重建表明，葡萄的弱爬能力和简化的卷须都进化了多次。这项研究为V.bryoniifolia进化枝提供了可靠的植物学框架。结合形态分析，我们讨论了V. bryoniifolia进化枝中某些分类单元的分类状态，并解开了葡萄属的分类分类难题。
