Root-specific expression of CMO/BADH driven by root-specific promoter PmPgPR10 was confirmed by detecting the enzyme activities of CMO and BADH in transgenic rice,which proved the root-specific promoter worked expectedly in transgenic rice.Other physiological and biochemical indexes and the salt-tolerance mechanism in transgenic plant were discussed as well.

运用松树根特异性启动子PmPgPR10驱动把CMO/BADH双价基因转入水稻.对转基因植株根和叶的CMO酶、BADH酶活性及其它生理生化指标进行了测定.结果表明:CMO/BADH双价基因能在根部特异性表达.文章还对转基因提高植株耐盐性的机理进行了探讨.

Salinity is one of the major limiting factors in plant growth and development.The selective movement of ions between intracellular compartments is fundamental for plants to enhance their salt tolerance.The AtNHX1 gene encodes a Na+/H+ antiporter,which is the key enzyme to transport Na+ into the vacuole to avert the deleterious effects of Na+ in the cytosol,it maintains the Na+ balance in cells and improves the salt-tolerance of plants.The characteristics of AtNHX1 gene and Na+/H+ antiporter AtNHX1,the salt tolerance mechanism of AtNHX1 are summarized in this paper,meanwhile,the relative genic engineering improvement for salt tolerance of plants is reviewed.

盐分是植物生长发育的主要限制因素之一,而离子在胞内区室之间的选择性运动对提高植物耐盐性是至关重要的。来自于拟南芥(Arabidopsis thaliana)的AtNHX1基因可编码Na+/H+逆向转运蛋白,而Na+/H+逆向转运蛋白AtNHX1可将细胞质中多余的Na+排进液泡来消除Na+的毒害,维持细胞的渗透平衡,提高植物的耐盐性。简要综述了AtNHX1基因及Na+/H+逆向转运蛋白AtNHX1的特征,AtNHX1的耐盐机制以及植物耐盐基因工程改良等方面的研究进展。

A salt-tolerance related gene STL (GenBank accession No. DQ234265) was isolated from Glycin max by rapid amplification of cDNA ends (RACE). The full-length cDNA of STL was 1 286bp and contained a 717 bp open reading frame (ORF) encoding 238 amino acids. Sequence analysis indicated that the deduced STL shared 63.6% identity with Arabidopsis thaliana salt tolerance protein STO (GenBank accession No. NP_849598). RT-PCR analysis revealed that after treated with 1mol/L NaCl for different duration,...

A salt-tolerance related gene STL (GenBank accession No. DQ234265) was isolated from Glycin max by rapid amplification of cDNA ends (RACE). The full-length cDNA of STL was 1 286bp and contained a 717 bp open reading frame (ORF) encoding 238 amino acids. Sequence analysis indicated that the deduced STL shared 63.6% identity with Arabidopsis thaliana salt tolerance protein STO (GenBank accession No. NP_849598). RT-PCR analysis revealed that after treated with 1mol/L NaCl for different duration, STL expression level in all the tested plant tissues did not change obviously, similar with that of STO in A. thaliana, suggesting similar salt-tolerance mechanism may exist between Arabidopsis and soybean.

利用RACE技术从大豆中克隆出一条耐盐相关基因STL(GenBank登录号为DQ234265),该基因全长为1286bp,其中编码区为717bp,编码一个由238个氨基酸组成的蛋白质。STL与拟南芥的耐盐蛋白STO(salttoleranceprotein,GenBank登录号NP_849598)具有63.6%的同源性。RT-PCR分析发现,当用1mol/LNaCl处理大豆叶片不同时间时,大豆STL的表达量并未发生显著变化,与拟南芥STO的表达模式相似,推测STL在大豆中也具有类似的耐盐功能。
