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 mono...葡萄属（Vitis L.）具有极高的农艺学价值，是一类经济价值突出的种质资源。数十年来，研究者们围绕葡萄亚属（subgenus Vitis）的系统发育关系开展了诸多探索。然而，在稳健的系统发育框架（phylogenetic framework）下，葡萄亚属多数形态性状的演化模式仍未得到系统解析。在东亚演化支（clade）中，V. bryoniifolia及其近缘类群共同构成了V. bryoniifolia演化支，该类群的分类学背景较为复杂。受既往研究采样范围有限的影响，该演化支内部的系统发育关系与物种界定问题迄今仍未得到充分解析。本研究依托系统基因组学框架（phylogenomic framework），通过祖先性状状态重建（ancestral character state reconstruction）对形态性状的演化展开了验证分析。本研究共采集东亚葡萄亚属的89份种质材料，利用限制性位点关联DNA测序（restriction-site associated DNA sequencing, RAD-seq）数据，重构出V. bryoniifolia演化支的稳健系统发育关系，研究结果支持其为单系（mono...）
