摘　　要：核孔复合物(nuclear pore complex,NPC)位于核膜,是控制细胞核与细胞质之间进行蛋白质和mRNA等大分子物质转运的唯一通道。模式植物拟南芥的核孔复合物由30多种多拷贝的核孔蛋白(nucleoporins,NUPs)构成,根据它们参与形成的亚基可分为外环、内环、连接、跨膜、中心FG(phenylalanine-glycine)和核篮核孔蛋白。核孔蛋白不仅介导核质转运,而且在植物多个生命进程中发挥重要作用。该文综述了植物核孔蛋白参与核质转运、激素信号响应、生长发育、环境胁迫应答、免疫防御等的研究进展,为植物核孔蛋白生物学功能的系统认知及深入探索提供参考。NPC (nuclear pore complex),embedding in the nuclear envelope,is the sole gateway channel that controls the trafficking of macromolecules such as proteins and mRNA between nucleus and cytoplasm.In Arabidopsis thaliana,the NPC consists of approximately 30 NUPs (nucleoporins) with multiple copies,which can be divided into outer ring,inner ring,linker,transmembrane,central FG (phenylalanine-glycine) and nuclear basket NUPs according to the sub-complex they formed.The NUPs not only modulate nucleocytoplasmic transport,but also play important roles in various biological processes.This review summarized the biological functions of plant NUPs involved in nucleocytoplasmic transport,hormone signaling,growth and development,responses to the environmental stress,plant immunity,which would lay the foundation for systematic cognition and further study on the biological functions of plant NUPs.
