There are some cases of symbiotic relation such as allelopathy, endphyte and symbiosis of Fabaseae plant. The growth and distribution of endophyte, Neothyphodium, in its host plant, tall fescue, Festuca arundinacea, were investigated during the seed germination stage under pseudo-microgravity. The hypheae of endophyte in the seed part were gradually unclear during the seed germination. Hyphae might be autolysis during seed germination. The wall component of endphyte was different during the earth control and pseudo-microgravity. A change in the carbohydrate metabolism of the fungus and the plant due to the pseudo-microgravity was suggested. We found the different functions of the endogenous enzyme grown under normal gravity and pseudo-microgravity. The mechanisms related to gravity during early germination stage of endophyte infected plant might be very complicated.
