英文摘要：

Endophyte is a kind of microbes, which exists in plants and is closely related to plant growth. Researches have been carried out and a lot of new progresses have been made, and some results have been applied in agricultural production. The research progress of active substances of endophyte and the relationship between endophytes and their host plants in recent years were summarized. Moreover, the appli- cation prospect of the endophytes in the future was forecasted.
