Molecular interactions of the phytotoxins destruxin B and sirodesmin PL with crucifers and cereals: Metabolism and elicitation of plant defenses

► Destruxin B is transformed by cruciferous species to hydroxydestruxin B. ► Destruxin B is transformed by cereals to four different destruxins. ► Sirodesmin PL is not transformed either by crucifers or cereals. ► Sirodesmin PL is a stronger elicitor of phytoalexins than destruxin B.
