Abstract
Wheat blast, caused by the fungus *Magnaporthe oryzae*, threatens global cereal production. This study demonstrates that the *Pm4* gene, previously known for conferring resistance to wheat powdery mildew, also confers resistance to wheat blast by recognizing the AVR-Rmg8 effector. *Pm4* alleles vary in their recognition of AVR-Rmg8 alleles, with some providing resistance only in seedling leaves, highlighting the need to select alleles effective in both leaves and spikes for durable resistance.
