Abstract:

Plant secondary metabolites have broad pharmacological activities and various biological functions. Biosynthesis of secondary metabolites has attracted much attention due to its low natural yield in plants and increasing demand of medicine. The plant and endophytes are long-tern mutual beneficial and symbiotic,and affects many metabolic processes and physiological activities of plants,which provides important source to solve the shortage of secondary metabolites. Here this paper reviews the biosynthesis of secondary metabolites,such as terpenoids,flavonoids and alkaloids,promoted by endophytes,as well as the regulation of secondary metabolites by endophytes to enhance plant resistance to biotic and abiotic stresses. The paper also discusses the production path and application prospect of endophytic associated plant secondary metabolites in modern biological field,aiming at providing ideal microbial resources for the biosynthesis of medicinal secondary metabolites and the improvement of crop stress tolerance.

Key words: endophytes, secondary metabolites, biosynthesis, biological defence, abiotic stress
