Interaction between endophytes and host plant and the role of endophytes in genuineness analysis of medicinal plant

Research of plant development and metabolism has drawn lots of attention with the fast development of science of mycorrhizal biology, molecular biology and metabonomics technology. It has become one of hot fields in the study of endophytes and plant, which would affect plant's metabolite composition. This would provide opportunity for appraising and modifying traits to medicinal plant, and would also perfect the tranditional standpoint on forming reason of medicinal plant genuineness. Here we provide a review of theory and mechanism, research and application of interaction between plant and endophyte. This review may enhance understanding of medicinal plant, and evaluating the quality of herbs in production.
