- •
Symbiosis with epichloid endophytic fungi was present in four out of nine grass species of a Patagonian steppe.
- •
Endophyte frequency and plant biomass of preferred grasses were lower under intense grazing.
- •
Despite host biomass was greater under grazing, endophyte frequency of non-preferred (toxic) symbiosis remained constant.
