Postglacial colonization history reflects in the genetic structure of natural populations of Festuca rubra in Europe
Abstract We conducted a large‐scale population genetic survey of genetic diversity of the host grass Festuca rubra s.l., which fitness can be highly dependent on its symbiotic fungus Epichloë festucae , to evaluate genetic variation and population structure across the European range. The 27 studied...
