An endophyte is a fungus that beneficial associations with some species of gramineous plants. The term of endophyte is a compound word made up of endo (within) and phyte (plant), and a general term for the infected microprobes in plata. The author investigated the endophyte in various parts of Japan and detected endophyte from many gramineous plants. It is possible to provide the endophyte infected, with insect resistance, disease resistance, and the resistance to environmental stresses. Endophyte infected and free plants were collected from fields in Japan. These plants are Festuca, Lolium, Poa, Agrostis, Phleum, Elymus, glyceria genus and so on. Endophyte infected plants leaves were cut off away, and they were sterilized. After that, they were laid in the PDA media and endophyte were isolated. These fungi were researched by the culture method on the slide glass. Many endophyte were Neotyphodium type. At persent, we are analyzing of alkaloids from these endophyte infected.
