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.
