    • It is intended to provide a gene encoding a protein having an activity of improving a tolerance to an environmental stress such as salt, moisture, or heat stress, in particular, a tolerance to water stress; a protein having an activity of improving a tolerance to an environmental stress; a transgenic plant having an enhanced tolerance to an environmental stress, and so on. A halophyte Salicornia europaea, which has a strong activity of improving a tolerance to water stress and can grow even in a dry area with much salt accumulation, was used to search genes participating in the salt tolerance of Salicornia europaea by a functional screening method using an Escherichia coli gene expression system, with the aim of isolating genes (cDNAs) participating in the salt-tolerance mechanism of Salicornia europaea. As a result, it was found out that an arabinogalactan protein consisting of 427 amino acids and having partial homology to a Fasciclin-like arabinogalactan protein of Arabidopsis thaliana has a function of enhancing salt tolerance, water stress tolerance (sorbitol tolerance), and heat tolerance.
    • 它的目的是提供编码具有对提高一个的环境胁迫耐受的活性的蛋白质的基因:如盐,水分,或热应力,特别是耐受水胁迫; 具有改进的容差对环境胁迫的活性的蛋白质; 具有增强的转基因植物对向环境压力,等等。 一个盐生植物海蓬子,其中有提高耐受水分胁迫较强的活性,能与很多盐分积累,其用于通过使用在功能性筛选方法来搜索参与海蓬子的耐盐基因的干燥区域甚至长出 大肠杆菌的基因表达系统,具有分离的基因(cDNA的)参加海蓬子的耐盐性机制的目的。 其结果是,它什么发现没有到阿拉伯半乳聚糖蛋白质的427个氨基酸由...组成和具有部分同源性的拟南芥的Fasciclin状阿拉伯半乳聚糖蛋白质具有强化耐盐性,水分胁迫耐受性(山梨醇公差)和耐热性的功能 ,
