Abstract:

Endophytes are widely present in various tissues and organs of healthy plants, and directly or indirectly act on parasitic plants through their own metabolites or by inducing plants to produce secondary metabolites, and play an important role in medicine, agriculture, horticulture, pollution prevention and control, and other fields. The interaction between plant endophytes and medicinal plants is also an important factor affecting the yield and quality of medicinal plants, and some endophyte metabolites of medicinal plants are similar or identical to the active ingredients of host plants. Rich achievements have been made in protection and utilization of medicinal resources, due to the study of germplasm resources classification and genetic diversity in medicinal plants, as well as isolation and identification of endophytic resources in Dendrobium officinale. In this review, the research status of endophytic species and biological activities in Dendrobium officinale were summarized, and the current status and existing problems of Dendrobium officinale cultivation were briefly described, so as to provide reference for the research of endophytic resources of Dendrobium officinale.

Key words: medicinal plants, Dendrobium officinale, endophytes, mutualism, secondary metabolites
