Diversity and distribution of Neotyphodium-infected grasses in Argentina

In the present work, we studied the presence of "epichloë/neotyphodium endophytes" in native grasses from Argentina. An extensive area of this country, representative of several different environments, was studied. Nine new host species of the genera Briza, Bromus and Poa were observed to...
