Resumen:
Although the role of fungal alkaloids in protecting grasses associated withEpichloë fungal endophytes has been extensively documented, the effects ofthe symbiont on the host plant?s immune responses have received little attention. We propose that, in addition to producing protective alkaloids, endophytes enhance plant immunity against chewing insects by promotingendogenous defense responses mediated by the jasmonic acid (JA) pathway.We advance a model that integrates this dual effect of endophytes on plantdefenses and test its predictions by means of a standard meta-analysis. Thisanalysis supports a role of Epichloë endophytes in boosting JA-mediated plantdefenses. We discuss the ecological scenarios where this effect of endophyteson plant defenses would be most beneficial for increasing plant fitness.
