摘要/Abstract

摘要： 植物细胞内膜体系与别的真核生物体系相似,由一系列连续的内膜结构组成,包括核膜、内质网、高尔基体、反式高尔基体、液泡、转运囊泡和细胞膜。其中,反式高尔基体和液泡具有植物细胞特有的结构特征和对应功能。从几个方面综述植物细胞内膜运输对植物发育的调控作用,包括内膜运输与生长素极性运输和稳态平衡之间的关系,内膜运输对根毛极性生长的作用机理,以及液泡运输在花粉管极性生长和种子萌发过程中的重要作用。旨在对致力于植物细胞内膜运输与发育调控的研究人员提供参考。

Abstract: Similar to other eukaryotic system,plant endomembrane system is a functionally inter-related membrane system including the nuclear envelope,the endoplasmic reticulum（ER）,the Golgi apparatus,the trans-Golgi network（TGN）,vacuoles,endosomes,plasma membrane（PM）and vesicles. It also displays some highly complex and unique characteristics,such as the unique feature of plant TGN and vacuole. This review mainly summarizes the regulatory mechanisms of plant endomembrane trafficking in plant development. We focus on the recent progresses about how endomembrane system regulate auxin polar transport and homeostasis,mechanism of root hair tip growth as well as the vacuole transport in the regulation of pollen tube tip growth and seed germination. We hope this review could be helpful to the researchers who study the process of plant growth,development and endomembrane trafficking.

Key words: plant endomembrane trafficking, polar transport, homeostasis, tip growth, seed germination
