植物SNARE蛋白的结构与功能

在真核生物细胞囊泡运输过程中的膜融合主要是由SNARE蛋白介导的,SNARE蛋白的结构高度保守.研究发现,植物中的SNARE蛋白促进植物细胞板形成,能与离子通道蛋白相互作用,有利于植物的正常生长发育,能提高植物的抗病性及参与植物的向重力性作用.应用基因组学和蛋白质组学技术结合细胞学水平上的分析方法有助于深入揭示植物SNARE蛋白家族成员的功能,明确SNARE蛋白在信号转导途径中的作用,阐明动植物免疫系统的区别和联系.

Structure and Function of SNAREs in Plant

The membrane fusion in vesicle trafficking in the cells of eukaryotic organisms is mediated by soluble-N-ethyl-maleimide-sensitive fusion protein attachment protein receptor (SNARE) proteins, which are highly conserved in their structures from various species, includ- ing yeast, animals and plants. Increasing research has demonstrated many tissue- or subcellular- specific components of SNAREs involved in the formation of the cell plate, interacting with ion channel proteins, and gravity sensing in plants. SNARE proteins might play important roles in plant growth, development and response to abiotic and biotic stresses. The application of genomics and proteomics approaches, as well cytological methods, will accelerate our under- standing of diverse functions of the plant SNARE family and their specific location in the signal transduction pathway, and the differentiation and relation between animal and plant immunity systems.
