A Phylogeny of the Genus Polemonium Based on Amplified Fragment Length Polymorphism (AFLP) Markers

The genus Polemonium is composed of animal-pollinated herbs found largely in North America. Wide phenotypic variation suggests rapid evolution of floral and vegetative morphology. However, phylogenetic relationships within Polemonium have received little attention. We present a phylogeny of Polemoni...

Zusammenfassung:The genus Polemonium is composed of animal-pollinated herbs found largely in North America. Wide phenotypic variation suggests rapid evolution of floral and vegetative morphology. However, phylogenetic relationships within Polemonium have received little attention. We present a phylogeny of Polemonium based on 1676 Amplified Fragment Length Polymorphisms (AFLPs). We obtained similar topologies through minimum evolution analysis using Nei-Li genetic distances and parsimony analysis. Our analyses supported the mono-phyly of most species, and indicated that the single annual species, P. micranthum, is sister to all perennial species. Relationships were well resolved among species separated by genetic distances
