摘要
细胞外囊泡是细胞在生理和病理条件下通过胞吐作用释放的具有磷脂双分子层结构的纳米级囊泡。细胞外囊泡作为蛋白质、核酸、脂质和代谢物等物质的载体,能够在细胞与细胞之间穿梭,行使物质传递、信息交流的功能,是细胞间通讯的重要媒介。近年来,植物中细胞外囊泡的研究也不断深入,其研究和分析技术也取得了很大进展。本文介绍了细胞外囊泡的组成,综述了植物中细胞外囊泡的生物学功能,分析了细胞外囊泡分离与富集方法的优缺点,以及原位成像技术的应用,最后对植物细胞外囊泡研究技术发展的重点进行了展望。
Extracellular vesicles(EVs)are nanoscale vesicles with a phospholipid bilayer structure released by cells through exocytosis under physiological and pathological conditions.EVs,as carriers of information such as proteins,nucleic acids,lipids,and metabolites,can shuttle between cells to play function of material transfer and information exchange,thus they are important for intercellular communication.In recent years,the research of EVs in plant has also been deepening,and there have been great progress in their research and analysis technologies.In this review,we briefly introduce the composition of extracellular vesicles.Then we summarize the current progress in the biological functions of EVs in plants.Furthermore,we analyze the advantages and disadvantages of EV isolation and enrichment methods,as well as the application of EVs in situ imaging technology.Finally,we prospect the potential technologies for the research of plant EVs.
