摘要

Rmg8 是普通小麦中抗麦瘟病的主要基因，对它的特性分析带来了一个惊喜：它是抗白粉病基因 Pm4 的变体。这两个基因都能识别麦瘟真菌 Magnaporthe oryzae pathotype Triticum（MoT）的 AVR-Rmg8 基因，从而产生对这种病原体的抗性。这一发现为开发抗麦穗瘟病的小麦品种开辟了道路。

Rmg8 gene against wheat blast

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.
