摘　　要：NPR(Nonexpressor of pathogenesis-related genes)家族蛋白为植物水杨酸(SA)受体,在细胞核内作为共转录因子参与植物多种生理过程。NPR蛋白功能多样性的发挥依赖于SA诱导下空间结构的变化,NPR空间结构变化为其功能发挥奠定结构基础。通过综述NPR家族蛋白在植物系统获得性抗性(SAR)、形态发育、冷胁迫、昼夜节律中发挥生物学功能以及NPR1、NPR1-TGA3(TGACG sequence-specific binding protein)复合物、NPR4空间结构的最新研究进展,为解决植物在胁迫条件下的培养问题提供新思路。NPR(Nonexpressor of pathogenesis-related genes)family proteins are plant salicylic acid(SA)receptors,which act as co-transcription factors to mediate various physiological processes in plants.The functional diversity of the NPR protein depends on the changes in the spatial structure induced by SA,and the changes in the spatial structure of the NPR lay the structural basis for their functions.By reviewing the latest research progress on biological functions of NPR family proteins in plant systemic acquired resistance(SAR),morphological development,cold resistance,circadian rhythm,and the spatial structure of NPR1,NPR1-TGA3(TGACG sequence-specific binding protein)complex,NPR4,so as to provide a new idea for solving the problem of plant cultivation under stress conditions.
