Molecular phylogenetic and taxonomic studies of Lamiaceae subfamily Lamioideae

TAXONOMY, SYSTEMATICS AND EVOLUTIONARY HISTORY

Molecular phylogenetic and taxonomic studies of Lamiaceae subfamily Lamioideae

The principal purpose of the present study has been to elucidate evolutionary relationships within subfamily Lamioideae using various molecular tools. The project is based mainly on herbarium specimens.

Purpurrote Taubnessel (Lamium purpureum)

Specifically the objectives have been:

  1. To identify major phylogenetic groups within subfamily Lamioideae, reveal their interrelationships, and to update their classification accordingly (publications 6 and 4). 
  2. To investigate the biogeographic history of subfamily Lamioideae and relate it to climatic and geological events of the past (close to submission).
  3. To identify major phylogenetic groups within tribe Stachydeae, reveal their interrelationships, and to update their classification accordingly (publications 1, 2, 7 and ongoing work).
  4. To investigate the biogeographic history of tribe Stachydeae and relate it to climatic and geological events of the past (ongoing work).
  5. To elucidate phylogenetic relationships and alloploid speciation in Lamium, the type genus of subfamily Lamioideae and Lamiaceae, and to evaluate Mennema’s (1989) subgeneric classification (publication 3 and 7).
  6. To test Müntzing’s (1932) hypotheses and conclusions about alloploid origin(s) of the two tetraploid Galeopsis species, G. bifida and G. tetrahit (publication 5).
  7. Methodological study on obtaining DNA sequences from old herbarium specimens (close to submission)
  8. To identify major phylogroups within the Lamiaceae and to update their tribal classification accordingly (publication 8).
