Abstract
Background and Aims: The evolutionary history of hornworts has been significantly explored through phylogenomic analyses, revealing unexpected complexities in the placement of Leiosporoceros, a putative sister lineage to other hornworts. Our understanding of the evolutionary history of hornworts and the role of incomplete lineage sorting (ILS) or ancient reticulation poses challenges in resolving their exact position and comprehending the diversification and evolutionary processes of hornworts. Methods: Using the GoFlag probe set, we sequenced 405 exons representing 234 nuclear genes, sampling 79 hornwort specimens, including representatives of all hornwort genera. We inferred the species phylogeny from gene tree analyses using concatenated and coalescence approaches, assessed ancient reticulation, ILS, and estimated the timing of divergences based on fossil calibrations.
