Because of rapid diversification and frequent interspecific gene flow within the genus inappropriate molecular markers used for phylogenetic studies, phylogeny evolution economically significant crop Vitis are poorly resolved understood, species delimitation remain disputable. In order to better understand relationships Vitis, phylogenomic analysis chloroplast genomes were performed based on extensive sampling scheme. Well tree clear divergence pattern obtained in present study. The results shows that subg. was constituted by three strongly supported monophyletic clades whose distributed North America, Europe Asia, respectively. Nine provided as potential DNA barcoding study Vitis. Furthermore, taxonomic position critically endangered endemic Northern China, V. baihuashanensis, is investigated suggested be a separate morphological comparisons, effective conservation actions badly needed. Molecular resources reported this could also genetic engineering studies will potentially promote genomic exploration wild relatives germplasm.
