摘要：

回顾与整理了樱亚属分类学的研究历史,对各主要樱亚属分类系统进行了概述。总结樱亚属植物实验分类学相关研究,认为形态学标记依然是樱亚属分类的基础;SSR标记研究可以为樱亚属种间及种内关系讨论提供证据;DNA序列标记在樱亚属分类研究中成果显著,基本厘清了樱亚属系统发育关系。整合樱亚属系统发育研究与地理分布最新数据,描绘了樱亚属系统发育主要框架,推测喜马拉雅山区至中国西南部或地中海地区为樱亚属起源地,总结了樱亚属迁移扩散的主要线路。结合文献与标本资料以及野外调查与最新研究结论,列出世界樱亚属物种名录共计76种(含11变种),并对樱亚属植物主要分布区及类群进行了统计;对山樱花复合群与大叶早樱复合群及其他争议类群,提出了分类处理观点。综合分析了樱亚属系统分类学研究现状,认为樱亚属复合体及存疑类群,以及中西部地区资源调查与分类整理等需要更深入的研究;大尺度下的多物种、多群体与多组学的组合探究,是樱亚属系统分类学研究的重要方向。

Abstract:

Reviewed and summarized the research history of the taxonomy of the subgenus Prunus subgen. Cerasus, provided an overview of major classification systems of the subgen. Cerasus. Summarized the advances in experimental taxonomy studies on the subgen. Cerasus, It is found that morphological markers play an important role in the classification of subgen. Cerasus. SSR marker studies can provide evidence for discussions on interspecific and intraspecific relationships within the subgen. Cerasus, DNA sequence markers have made important achievements in the study of subgen. Cerasus classification, essentially clarifying the phylogenetic relationships within the subgen. Cerasus. Integrated the latest data on phylogeny and geographic distribution of the subgen. Cerasus, outlined the main framework of the phylogeny of the subgen. Cerasus, speculation that the origin of this subgenus is from the Himalayan region to southwestern China or the Mediterranean region, summarized the main migration routes of the subgen. Cerasus. By combining literature and specimen data, field surveys and recent research conclusions, a total of 76 species of the subgen. Cerasus (including 11 varieties) were listed in the world species catalog, and statistical analysis was conducted on the main distribution areas and groups of the subgen. Cerasus; proposed classification viewpoints for the P. serrulata complex, P. subhirtella complex, and other controversial groups. A comprehensive analysis of the status of the taxonomy of the subgen. Cerasus, suggesting that more in depth research is needed on the complex and controversial groups within the subgen. Cerasus, as well as resource surveys and classification in the central and western regions; exploring combinations of multiple species, populations, and omics at a large scale is an important direction for the taxonomy research of the subgen. Cerasus.

Key words: Prunus subgen. Cerasus, taxonomy, phylogeny, comples
