Cytonuclear discordance
WebJun 18, 2024 · Topological cytonuclear discordance is commonly observed in plant phylogenetic and phylogeographic studies, yet few studies have attempted to detect two other forms of cytonuclear discordance (branch length and geographical) and to uncover the causes of the discordance. WebAn ancient chloroplast capture event in the Eocene in western North America best explains the cytonuclear discordance. Our conflict analysis dem-onstrated that ILS, hybridization, and allopolyploidy could explain the widespread nuclear gene tree dis-cordance. One deep hybridization event (Malus doumeri) and one recent event (Malus coronaria ...

The introgression likely occurred prior to the invasion, but genetic information on the native range and commercial trade is needed for verification.
WebOct 12, 2009 · We tracked cyto-nuclear discordance across section Galoglychia as evidence for hybridization. To achieve a proper global view, we first clarified the monophyly of section Galoglychia as it had been questioned by recent phylogenetic studies. Moreover, we investigated if fig size could be a factor facilitating host shifts. Results
