The function of endophyte and the relationship between the endophyte and their host plant are investigated. Endophyte-infested tall fescue (Festuca arundinacea) and endophyte-free tall fescue are used as plant materials in this study. The seeds of endophyte-infected tall fescue were stained by aniline blue and then observed under a light microscope. The fungal hyphae are well observed by this method. It was observed that fungal hyphae grow with seed development. After the extraction from the infected seeds and un-infected seeds with distilled water, these extracts were analysed by a HPLC. The different chromatograms between the infected seeds and un-infected seeds are found. These results suggest that the endophyte releases some chemical substances into the environment when they begin to grow with seed germination.
