The vesicle trafficking apparatus is a fundamental machinery to maintain the homeostasis of membrane-enclosed organelles in eukaryotic cells. Thus, it is broadly conserved in eukaryotes including plants. Intensive studies in the model organisms have produced a comprehensive picture of vesicle trafficking in yeast and human. However, with respect to the vesicle trafficking of plants including rice, our understanding of the components and their coordinated regulation is very limited. At present, several vesicle trafficking apparatus components and cargo proteins have been identified and characterized in rice, but there still remain large unknowns concerning the organization and function of the rice vesicle trafficking system. In this review, we outline the main vesicle trafficking pathways of rice based on knowledge obtained in model organisms, and summarize current advances of rice vesicle trafficking. We also propose to develop methodologies applicable to rice and even other crops for further exploring the mysteries of vesicle trafficking in plants.
囊泡运输装置是维持真核细胞中膜封闭细胞器内稳态的基本机制。因此，它在包括植物在内的真核生物中广泛保守。在模式生物中的深入研究已经描绘出了酵母和人类中囊泡运输的全貌。然而，对于包括水稻在内的植物的囊泡运输，我们对其组成成分及其协调调控的了解非常有限。目前，已经在水稻中鉴定并表征了几种囊泡运输装置的组成成分和货物蛋白，但关于水稻囊泡运输系统的组织和功能仍然存在很大的未知。在这篇综述中，我们基于在模式生物中获得的知识概述了水稻的主要囊泡运输途径，并总结了水稻囊泡运输的当前进展。我们还建议开发适用于水稻甚至其他作物的方法，以进一步探索植物中囊泡运输的奥秘。
