Metabolomic changes ofA. sibiricum in response to endophytes
Compared to the control, the endophytic infection resulted in 58 DMs before pathogen inoculation (Fig. S2a) and 157 DMs after pathogen inoculation (Fig. S2b). There were 8 common DMs (Fig. S2c). Among them, the contents of arginyl-proline, 4-methyl-5-thiazoleethanol, and aspergillomarasmine A were considerably higher in the EI leaves compared to those in the EF (Fig. 1).
