Cell polarization is intimately linked to plant development, growth, and responses to the environment. Major advances have been made in our understanding of the signaling pathways and networks that regulate cell polarity in plants owing to recent studies on several model systems, e.g., tip growth in pollen tubes, cell morphogenesis in the leaf epidermis, and polar localization of PINs. From these studies we have learned that plant cells use conserved mechanisms such as Rho family GTPases to integrate both plant-specific and conserved polarity cues and to coordinate the cytoskeketon dynamics/reorganization and vesicular trafficking required for polarity establishment and maintenance. This review focuses upon signaling mechanisms for cell polarity formation in Arabidopsis, with an emphasis on Rho GTPase signaling in polarized cell growth and how these mechanisms compare with those for cell polarity signaling in yeast and animal systems.

拟南芥中的细胞极性信号传导。

细胞极化与植物的发育,生长以及对环境的反应密切相关。由于最近对几种模型系统的研究,例如花粉管中的尖端生长,叶表皮中的细胞形态发生以及PIN的极性定位,我们对调节植物细胞极性的信号传导途径和网络的理解取得了重大进展。从这些研究中,我们了解到植物细胞利用保守机制(例如Rho家族GTPases)整合植物特异性和保守极性线索,并协调极性建立和维持所需的细胞骨架动态/重组和囊泡运输。这篇综述着重于拟南芥中细胞极性形成的信号传导机制,
