Ergovaline in populations of endophyte infected Festuca rubra subsp. pruinosa
Festuca rubra subsp. pruinosa is a grass whose preferred habitat are coastal cliffs, a harsh environment where plants grow in cavities and are exposed to salt water spray. This grass species is systemically infected by the fungal endophyte Epichloë festucae and the interaction is asymptomatic. Endop...

Festuca rubra subsp. pruinosa is a grass whose preferred habitat are coastal cliffs, a harsh environment where plants grow in cavities and are exposed to salt water spray. This grass species is systemically infected by the fungal endophyte Epichloë festucae and the interaction is asymptomatic. Endophyte infected grasses produce several alkaloids toxic to herbivores. In a previous work, we showed that an average of 69% of Festuca rubra subsp. pruinosa plants from cliff ecosystems (in the North Atlantic coast of Galicia region –Spain-) were infected by the endophyte Epichloë festucae.
