Cerastium

Cerastium je rod koji obuhvaća oko 200 vrsta zeljastih biljaka najvećim dijelom rasprostranjenih u umjerenim i hladnim područjima, sa središtem rasprostranjenosti na Balkanskom poluotoku i zapadnoj Aziji. Istraživat ćemo evoluciju visokopoliploidnog kompleksa višegodišnjih balkanskih i alpskih vrsta (npr. grupe C. alpinum i C. banaticum) i njihove veze s arktičkim svojtama. Među vrstama koje će se istraživati je i Cerastium dinaricum, vrsta s popisa Natura 2000 te stoga i prioritetna vrsta za opsežne EU konzervacijske mjere.

Selected results
The rare mountain plant Cerastium dinaricum is endemic to the Dinaric mountains. Employing amplified fragment length polymorphisms (AFLPs), nuclear ribosomal ITS and plastid ndhJ-trnT sequences as well as relative genome size data, we examined the species’ phylogeographic structure in order to provide a basis for the designation of tailored conservation strategies. Analyses of various datasets congruently revealed two genetic groups with NW/SE vicariant distribution. a, population graphs based on AFLP profiles; b, NeighbourNet diagram based on AFLPs; c, Nei`s gene diversity; d, frequency down weighted marker values; e, STRUCTURE clustering of the AFLP data from separate analyses of the NW and the SE group; f, statistical parsimony network and geographic distribution of plastid DNA haplotypes.
