Abstract:

As one of the major crops, the production of rice affects the global food security. Rice blast caused by Magnaporthe grisea is a worldwide disease, which seriously threatens the stable and high yield of rice. Studying the interaction mechanism between rice and rice blast fungus and applying it to the breeding of resistant varieties is an effective and environmentally friendly means to overcome the rice blast. This article reviewed the interaction mechanism between rice and rice blast fungus, including the pathogenic elicitors, innate immune responses in rice against rice blast fungus, and maintaining toxicity in fungi.

Key words: rice, rice blast fungus, interaction, effector molecule, immunological reaction

摘要：

作为主要粮食作物之一，水稻的生产影响着全球粮食安全。由稻瘟病菌引起的稻瘟病是世界性水稻病害，严重威胁着水稻的高产稳产，给水稻生产造成严重损失。深入研究水稻－稻瘟病菌互作机制，并应用于抗性品种的选育，是克服稻瘟病的环保且有效的手段。本文从稻瘟病菌激发子、水稻抗稻瘟病免疫应答反应及稻瘟病菌维持毒性的机制等方面对水稻与稻瘟病菌互作机制研究进展进行了综述。
