摘要: 为适应丰富多变的生存环境, 植物逐渐进化出一套复杂的免疫系统来抵抗病原菌的侵染。核苷酸结合的富含亮氨酸重复蛋白(NLR)作为植物体内普遍存在的一类抗性(R)蛋白, 对植物的抗病性具有重要调控作用。该文综述了NLR蛋白结构、信号转导以及对植物抗病的调控作用近几年的研究进展。

关键词: NLR, 植物免疫, 抗性蛋白, 信号转导

Abstract: In order to adapt to various living environments, plants have gradually evolved a complex immune system against the infections caused by pathogens. The nucleotide-bounding leucine-rich repeat proteins (NLRs) act as typical resistance (R) proteins which commonly exist in plants and play an important role in regulating plant disease resistance. In this paper, the research progress of NLRs is reviewed from the aspects of NLR protein structures, signal transductions and regulations of plant disease resistance.

Key words: NLR, plant immunity, resistance protein, signal transduction
