Description of Project
The primary goal of this project is to reveal the biogeographic history of Lamiaceae subfamily Lamioideae (including Pogostemonoideae), with special focus on one large and widely distributed subgroup, Stachys s.l., and two smaller temperate Eurasian genera, Lamium and Galeopsis. Materials used in this project include dried plant specimens from various herbaria as well as freshly collected and variously preserved plant material from the field. Comparative DNA sequence analysis is used for examining the evolutionary and biogeographic histories of taxa.
- Subfamily Lamioideae of the Lamiaceae was recently subjected to studies of molecular phylogeny (ourselves). The present project aims to reconstruct the biogeographic history of Lamioideae by using molecular age estimation and various ancestral area analysis tools. Collaborators: Olof Ryding (Botanical Museum,Copenhagen), Stephan Nylinder (Univ. of Gothenburg), and possibly others…
- Stachys, the largest and most widely distributed of all lamioid genera (>300 species), represents an unnatural group as currently recognized. Comparative DNA sequence analysis is used to illuminate interspecific phylogenetic relationships and to identify monophyletic groups within this large and polyphyletic assemblage, tribe Stachydeae. Accomplishments during this project will form the basis for historical biogeographic and taxonomic revisionary work of Stachys and other genera in tribe Stachydeae. Materials used in this project include dried plant specimens from various herbaria as well as freshly collected and variously preserved plant material from the field. Collaborators: Olof Ryding (Botanical Museum, Copenhagen), Lisbeth Thorbek (NHM, Univ. of Oslo), Charlotte Lindqvist (Univ. at Buffalo), Janet Barber (Saint Louis Univ.), Yasaman Salmaki (Univ. of Tehran), and Christian Bräuchler (Univ. of Munich).
- The genus Galeopsis belongs to Lamiaceae subfamily lamioideae and comprises about ten species, all of which have their centers of diversity in Europe. The genus consists two subgenera, subg. Galeopsis and subg. Ladanum. Subg.Galeopsis was recently subjected to studies of allopolyploid speciation (ourselves). The present investigation aims to illuminate the evolutionary history of the whole genus using various kinds of molecular approaches. Collaborators: Andreas Tribsch (Univ. of Salzburg), Liv Borgen (NHM, UoO), Anne K. Brysting (Dept. Biology, UoO), and Pavel Travnicek (Charles Univ. in Prague).
