摘要: 真菌病害是植物病害中最为严重的一种,世界上70%—80%的植物病害都是由真菌引起。几丁质是病原真菌细胞壁的重要组成成分,是一种典型的病原相关分子模式(pathogen-associated molecular pattern,PAMP)。当植物受到病原真菌入侵,位于细胞膜上的模式识别受体(pattern recognition receptor,PRR)能够直接与几丁质及其寡糖相互作用并触发植物的免疫反应。近几年,随着植物几丁质受体的成功鉴定,其与几丁质的相互作用机制以及几丁质触发植物免疫的分子机理被广泛研究,并取得了许多重要进展。为了较全面、系统地反应几丁质触发免疫研究的历史沿革、研究现状和发展趋势,笔者就植物对几丁质的识别机制、信号转导以及病原真菌对几丁质触发的免疫反应的抑制机制这3方面进行了综述,并对未来研究的发展方向进行了探讨。

Abstract: Fungal diseases are the most serious plant diseases, and about 70%-80% plant diseases are caused by fungi worldwide. Chitin, a major component of fungal cell walls, is a typical pathogen-associated molecular pattern. When plant is attacked by fungal pathogens, the pattern recognition receptors located on the plasma membrane can recognize chitin and chitin oligosaccharide and trigger plant innate immunity. In recent years, the plant chitin receptors have been successfully identified. Subsequently, the molecular mechanism of interactions between chitin and its receptors and how the chitin triggered innate immunity were studied intensively. To comprehensively, systemically introduce the history, research status and development trend of chitin triggered immunity, the chitin recognition mechanism, signal transduction and fungal pathogen suppressing chitin triggered innate immunity were summarized. Additionally, research directions of chitin triggered immunity were discussed.
