Entwicklung und Optimierung von neuartigen phylogenomischen Methoden zur Aufklärung der Artenvielfalt und Evolution im Tribus Cichorieae (Compositae/Korbblütler), die wichtige Erkenntnisse zum Stammbaum der Korbblüterfamilie liefern.
Zusammenfassung der Projektergebnisse
We used a hybrid capture kit to target 1061 low copy loci that are potentially orthologous across the Asteraceae and generated a dataset containing almost 200 samples of Scorzonerinae and outgroups from across the tribe Cichorieae. Our taxon sampling contained ~30 species native to Iran that had not been analysed in a phylogenetic context before. By conducting a range of phylogenetic analyses the resulting phylogeny is better resolved than in previous studies and improve our understanding of the relationships within Scorzonera. Our results provide a baseline for divergence time estimations and ancestral biogeography estimations of Scorzonera. Establishing the Hyb-Seq approach as a method for phylogenetic research in the Cichorieae tribe of the Asteraceae, opens new research opportunities where previous methods failed.
