Endophyte Mycorrhizae Relationship

Mycorrhizae generally are regarded as beneficial fungi in that they assist plant roots in absorbing minerals. Tall fescue plants infected with N. coenophialum (Guo et al., 1992) and N. lolii-infected perennial ryegrass plants (Liu et al., 2007) had considerably less colonization of roots by the mycorrhizae Glomus macrocarpum Tul. & C. Tul. and G. mosseae (T.H. Nicolson & Gerd.) Gerd. & Trappe than noninfected plants. Sporulation of mycorrhizae also was reduced in E+ tall fescue.
