摘要：

青枯劳尔氏菌（简称“青枯菌”）可在多种作物上引发细菌性青枯病，严重威胁全球作物的安全生产。青枯菌遗传多样性高、变异快，目前生产上缺乏有效的抗病品种，这给青枯病的防治带来了挑战。挖掘植物中识别青枯菌相关分子模式或效应子的受体蛋白，并解析其识别的分子机制，可为认识植物与青枯菌的互作机制提供线索，同时为植物广谱抗病性的创制奠定理论基础。本文综述了近年来植物与青枯菌识别的分子基础研究进展，重点介绍了植物中识别青枯菌的膜上受体和胞内受体的鉴定、功能解析，以及受体与青枯菌相关分子模式或效应子的识别机制，并对今后青枯病防控中抗病资源的挖掘和利用进行了展望。

Abstract:

Ralstonia solanacearum causes bacterial wilt disease in multiple crops, which severely threatens the global crop safety production. This pathogen exhibits high genetic diversity and evolves rapidly, and there is a lack of effective disease-resistant varieties in production, which brings great challenges for effective disease control. Identifying receptor proteins in plants that recognize associated molecular patterns or effectors of R. solanacearum and elucidating their molecular recognition mechanisms can provide clues to understand the mechanisms of plant-pathogen interaction, and lay a basis for the development of broad-spectrum disease resistance in plants. This paper reviewed the recent progress on the molecular basis of plant-R. solanacearum recognition. We mainly focused on the identification and functional analysis of membrane and intracellular receptors that recognize R. solanacearum in plants, as well as the mechanism behind receptor recognition of the associated molecular patterns or effectors from R. solanacearum. Besides, we provide research prospects for the exploration and utilization of disease-resistant resources against R. solanacearum in the future.

Key words: Ralstonia solanacearum recognition effector resistance protein
