Peramine and other fungal alkaloids are exuded in the guttation fluid of endophyte-infected grasses

Peramine was detected by LCMSMS in guttation fluid and cut leaf fluid of grass-endophyte associations. In some associations we also detected loline and ergot peptide alkaloids. This is the first report establishing the mobilization of fungal alkaloids into plant fluids in the grass-endophyte symbiosis.
