摘　　要：细胞的极性生长可以作用于植物生长发育等一系列生物活动。其中花粉管的极性生长在被子植物有性生殖过程中发挥重要的作用。多种信号通路协同调控花粉管的极性生长,ROP (Rho-related GTPases of plants)所介导的信号途径是花粉管极性生长调控网络中的主要参与者,也是植物其他细胞极性生长的关键调节因子。本研究将以拟南芥等植物的花粉管作为对象,对ROP信号途径进行简要叙述,旨在更全面地展现ROP在花粉管极性生长中的分子机制,为植物小G蛋白ROP的功能研究提供借鉴。College of Horticultural Science and Engineering, Shandong Agricultural University;The polar growth of cells can affect a series of biological activities such as plant growth and development. The polarity of pollen tubes plays an important role in the sexual reproduction of angiosperms. Multiple signaling pathways synergistically regulate the polar growth of pollen tubes, ROP(Rho-related GTPases of plants) signaling is the major participant in the pollen tube polarity regulation network, and it is also the key regulator of the other cell polar growth in plants. In this study, pollen tubes of plants such as Arabidopsis thaliana were used as objects to briefly describe the ROP signaling pathway, aiming to more fully demonstrate the molecular mechanism of ROP in polar growth of pollen tubes, and provide reference for the functional study of plant small G protein ROP.
