Resistance genes

Rmg8 gene against wheat blast

Nature Plants volume 10, pages 836–837 (2024)Cite this article

Subjects

Characterization of Rmg8, the major resistance gene for wheat blast found in common wheat, brought a surprise: it is a variant of Pm4, a resistance gene for powdery mildew disease. Both genes recognize the AVR-Rmg8 gene of the wheat blast fungus Magnaporthe oryzae pathotype Triticum (MoT), which results in resistance against this pathogen. This discovery opens avenues for developing wheat varieties to combat wheat blast disease.
