摘　　要：细胞骨架是真核细胞的重要组成成分,广泛参与了包括细胞形态建成、细胞器运动、胞内物质运输和信息传递等在内的许多细胞生理活动.已有研究表明,细胞骨架系统在开花植物有性生殖的重要环节——花粉萌发及花粉管生长过程中发挥重要作用.本文针对该过程中细胞骨架系统的组织结构、动态变化及功能调控等进行系统综述,以期使读者深入理解细胞骨架系统在花粉极性建立和维持过程中的重要作用.Cytoskeleton is an important component of eukaryotic cells,which is widely involved in a variety of physiological activities,including cell morphogenesis,organelle movement,intracellular transport and communication.Previous studies have shown that cytoskeleton system plays an important role in pollen germination and pollen tube growth,both are the essential steps for flowering plant sexual reproduction process.In this review,the organizational structure,dynamic changes and functional regulation of cytoskeleton system during pollen germination and pollen tube growth were summarized,in order that readers can deeply understand the significant role of cytoskeleton system during pollen polarity establishment and maintenance.
