Endophyte is a factor that affects the physiology and metabolism of plant. However, limited information is available on the mechanism of interaction between endophyte and plant. To investigate the effects of endophytic fungus ZPRs-R11, that is,  Trimmatostroma  sp., on salidroside and tyrosol accumulations in  Rhodiola crenulata , signal transduction, enzyme gene expression, and metabolic pathway were investigated. Results showed that hydrogen peroxide (H 2 O 2 ), nitric oxide (NO), and salicylic acid (SA) involved in fungus-induced salidroside and tyrosol accumulations. NO acted as an upstream signal of H 2 O 2  and SA. No up- or down-stream relationship was observed, but mutual coordination existed between H 2 O 2  and SA. Rate-limiting enzyme genes with the maximum expression activities were UDP-glucosyltransferase, tyrosine decarboxylase ( TYDC ), monoamine oxidase, phenylalanine ammonialyase ( PAL ), and cinnamic-4-hydroxylase sequentially. Nevertheless, the genes of tyrosine transaminase and pyruvate decarboxylase only indicated slightly higher activities than those in control. Thus, TYDC and PAL branches were the preferential pathways in ZPRs-R11-induced salidroside and tyrosol accumulation.  Trimmatostroma  sp. was a potential fungus for promoting salidroside and tyrosol accumulations. The present data also provided scientific basis for understanding complex interaction between endophytic fungus and  R. crenulata .
