摘要:

为了应对外界复杂的环境变化, 植物进化出一套复杂而精细的免疫应答调控机制。植物抗病蛋白能够特异地识别病原微生物分泌的效应蛋白, 触发免疫响应以对抗病原微生物的侵扰。该文综述了植物抗病蛋白的结构与功能及对病原菌的识别方式、在免疫响应过程中抗病蛋白的动态平衡机制及其介导的防御反应信号转导。开展植物抗病蛋白研究可为定向培育抗病作物奠定理论基础。

Abstract:

Plants have evolved a continuously co-evolutionary and sophisticated immune surveillance system to help themselves adapt to environmental changes. Disease resistance (R) proteins play an important role in activating potent defense responses by recognizing specific effectors to protect against microbial infection. In this review, we outline recent progress in plant R proteins, focusing on the structure and function, pathogen recognition, homeostasis control mechanisms, and potential activation mechanisms in R-mediated defense responses. These studies provide valuable information for developing transgenic plants with improved pathogen resistance.
