Molecular variation in Leymus species and populations
Icelandic populations of European lymegrass [ Leymus arenarius (L.) Hochst.] were examined using amplified fragment length polymorphism (AFLP) and restriction fragment length polymorphism (RFLP) of the major ribosomal genes (18S–5.8S–26S rDNA), in comparison with Alaskan populations of its closely r...

Icelandic populations of European lymegrass [ Leymus arenarius (L.)

The AFLP profiles emerged as two distinct entities, clearly separating the two species, and based on species‐specific bands it was simple to distinguish these two morphologically similar species. The rDNA–RFLPs also differentiated the species.
