| Abstract/Contents: | "The distribution of N-formyl and N-acetyl lolines, peramine, lolitrem and ergobaline was determined in Acremonion spp. and Epichloe typhina infected cultivars and species of Festuca, Lolium and other grass genera. Thirty of 34 host-fungus combinations produced alkaloids, peramine and ergovaline were the most common found alkaloids, while lolines and lolitrem were the least common. Three alkaloids (lolines, peramine, and ergovaline) were recovered from A. coenophialum-infected tall fescue and perennial ryegrass, while peramine, lolitrem andergovaline were present in A. lolii infected perennial ryegrass, tall fescue, and in E. typhina infected F. longifolia. Other host-fingus combinations produces only one or two of these alkaloid types. Aphid bioassays, using infected grass stems, indicated that loline alkaloids were toxic to Rhopalosiphum padi(Rp) and Schizaphis graminum(Sg); peramine was toxic only to Sg and ergovaline was not toxic to either aphid. Lolitrem was not toxic to Rp, but it could not be determined if the alkaloid was toxic to Sg as peramine was always present in the same infected grasses. The relationship of alkaloid synthesis in infected grasses and resistance to herbivory will be discussed. |
