Plant nucleocytoplasmic transport beyond the nuclear envelope is important not only for basic cellular functions but also for growth, development, hormonal signaling, and responses to environmental stimuli. Key components of this transport system include nuclear transport receptors and nucleoporins. The functional and physical interactions between receptors and the nuclear pore in the nuclear membrane are indispensable for nucleocytoplasmic transport. Recently, several groups have reported various plant mutants that are deficient in factors involved in nucleocytoplasmic transport. Here, we summarize the current state of knowledge about nucleocytoplasmic transport in plants, and we review the plant-specific regulation and roles of this process in plants.
植物核质运输超出核膜范围不仅对基本细胞功能很重要，而且对生长、发育、激素信号传导以及对环境刺激的反应也很重要。该运输系统的关键组成部分包括核运输受体和核孔蛋白。受体与核膜中核孔之间的功能和物理相互作用对于核质运输是不可或缺的。最近，几个研究小组报道了多种缺乏参与核质运输因子的植物突变体。在这里，我们总结了目前关于植物核质运输的知识现状，并回顾了该过程在植物中的特异性调控及其作用。
