Is the endophyte‐based plant protection against aphids mediated by changes in the insect microbiome? We showed that the fungal endophyte Epichloë strain AR37 increased the plant resistance against aphids via the production of indole diterpene alkaloids. The reduction in aphid performance was not ass...
