Abstract
A set of newly designed Vitaceae baits targeting 1013 genes was employed to explore phylogenetic relationships among North American Vitis. Eurasian Vitis taxa including Vitis vinifera were found to be nested within North American Vitis subgenus Vitis. North American Vitis subgenus Vitis can be placed into nine main groups: the Monticola group, the Occidentales group, the Californica group, the Vinifera group (introduced from Eurasia), the Mustangensis group, the Palmata group, the Aestivali group, the Labrusca group, and the Cinerea group. Strong cytonuclear discordances were detected in North American Vitis, with many species non-monophyletic in the plastid phylogeny, while monophyletic in the nuclear phylogeny. The phylogenomic analyses support recognizing four distinct species in the Vitis cinerea complex in North America: V. cinerea, V. baileyana, V. berlandieri, and V. simpsonii. Such treatment will better serve the conservation of wild Vitis diversity in North America.
