Identification of Aglaia-parasitic Ophiocordyceps sp. BRM1.
(A) Image of a parasite fungus growing on Aglaia odorata. (B) Multilocus phylogenetic tree of Ophiocordyceps species generated from maximum likelihood phylogenetic analysis of ITS, SSU, LSU, RPB1, and TEF1α sequences. Tolypocladium species were used as outgroups. The best DNA substitution models of ITS, LSU, SSU, RPB1, and TEF1α were calculated as TIM3ef + G4, TIM1 + I + G4, TIM3ef + I + G4, TrN + I + G4, and TIM1 + I + G4, respectively. Numbers on branches are percent support values out of 1000 bootstrap replicates. Only bootstrap values greater than 50% support are shown. Endophytes are highlighted with green dots.

Model of the plant–fungus arms race evoked by rocaglates.
The ancestors of the Aglaia plants may have been subjected to fungal infection. To counteract this, Aglaia plants may have developed rocaglates to target the conserved translation factor eIF4A and to suppress in planta fungal growth. Simultaneously, Aglaia plants exhibit amino acid substitutions in the rocaglate binding pocket of eIF4As to prevent self-poisoning. Some fungi may impede rocaglate toxin by converting eIF4A to a rocaglate-insensitive form, enabling them to parasitize these plants.
