Many grasses live in association with fungi (Neotyphodium spp. endophytes) growing in the intercellular spaces of the grass. The endophytes produce a range of alkaloids that protect the grass against grazing animals and insects. There has been speculation about the mobilisation and translocation of different alkaloids. We aimed to determine if metabolites produced by endophytes are mobilised and translocated by the plant. We developed a versatile method for the analysis plant fluids, using a linear ion trap mass spectrometer. Cut leaf fluid and guttation fluid of different grass endophyte associations in ryegrass and tall fescue were analysed. Peramine was detected in the cut leaf and guttation fluid of all ryegrass-endophyte associations that are able to produce peramine, but were found only in the cut leaf fluid of the tall fescue association. Lolines and ergot peptides were also detected in some associations. Keywords: Neotyphodium, ryegrass, tall fescue, guttation, peramine, ergovaline, loline
