AM fungi root colonization increases the production of essential isoprenoids vs. nonessential isoprenoids especially under drought stress conditions or after jasmonic acid application

► We analyze the effects of AM symbiosis on plant isoprenoids production. ► AM symbiosis favoured the production of leaf essential isoprenoids. ► AM fungi root colonization caused a decrease in the root isoprenoid content. ► Drought stress and jasmonic acid application affected plant isoprenoid production. ► Overall, these effects might depend on different partitioning between isoprenoids.
