土壤盐渍化已经成为严峻的世界性问题，严重威胁着农业生产和生态安全，筛选培育耐盐植物是适应和改良土壤盐渍化的有效途径。白刺具有极强的耐盐特性，探明白刺盐胁迫耐盐机制，解析相关膜蛋白的作用机制，对改良和利用盐渍化土地具有理论和实践意义。本项目以Na+区隔化机制为切入点，探究膜离子转运相关蛋白在植物耐盐机制中的作用及作用方式，同时将Ca2+引入到该研究中，通过研究白刺在整株和细胞水平上及基因表达、翻译和活性水平上研究不同浓度NaCl及外源Ca2+处理下对植物生长、液泡膜上与Na+区隔化相关蛋白的作用、质膜上与Na+外排相关蛋白的作用，探讨西伯利亚白刺在盐胁迫下的离子区域化机制及外源Ca2+的调控效应。

Soil salinization has become a serious worldwide problem, serious threat to agricultural production and ecological safety, selection and cultivation of salt tolerant plants is an effective way to adapt and improve the soil salinization. Salt tolerance of Nitraria is extremely strong, understand the salt tolerance of thorn probe mechanism, mechanism analysis associated membrane protein, the improvement and utilization of saline alkali soil has theoretical and practical significance. This project is based on the Na+ segmentation mechanism as a strating point, study of membrane ion transport related protein resistance and role in the mechanism of plant salt., at the same time, Ca2+ will be introduced to the study, thtough the study of Nitraria in the whole plant and cell level and in gene expression, translation and the level of activity of the research on plant growth under different concentrations of NaCl and exogenous Ca2+ treatment, the segment of the tonoplast and Na+ area related protein, plasma membrane and Na+ row associated protein to investigate the Nitraria sibirica Pall.. Effects of the ion compartment mechanism and exogenous Ca2+ under salt stress.
