Molecular systematic of Gesneriaceae

Molecular systematic of Gesneriaceae

Molecular systematic of Gesneriaceae

Stakeholders: M. Perret, A. Chautems

This long-term project seeks to reconstruct the history of Gesneriaceae, with a special focus on the Neotropical lineages. Phylogenetic analyses based on multiple DNA regions from the nucleus and the plastid genomes are undertaken at a global level or within specific clades of Gesnerioideae such as the Ligeriinae, Sphaerorrhizinae, Columneinae, Gloxinieae, and Beslerieae. These works provide the necessary framework for the monographic revisions of these groups and a better understanding of their evolution.
