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.

Rmg8基因抗小麦瘟病


Rmg8是普通小麦中发现的麦瘟病主要抗性基因，其特征令人惊讶：它是白粉病抗性基因Pm4的变体。这两个基因均识别小麦瘟疫真菌 Magnaporthe oryzae 致病型小麦 (MoT) 的 AVR-Rmg8 基因，从而产生针对该病原体的抗性。这一发现为开发抗击麦瘟病的小麦品种开辟了道路。
