摘要:
为了克隆盐生植物海滨锦葵耐盐基因KvSOS1并构建其表达载体,采用RT-PCR和RACE方法从海滨锦葵中克隆了质膜Na+/H+转运蛋白基因KvSOS1(GenBank登录号KJ577576)的全长cDNA序列,长度为3 850 bp,其中开放阅读框长度为3 444 bp。KvSOS1基因编码1个由1 147个氨基酸残基组成的蛋白,分子量为127.56 ku,理论等电点pI为6.18。疏水性分析结果表明,该蛋白N-末端具有高度疏水性,并含有11个跨膜区,C-末端为1个长约700个氨基酸残基的亲水性尾巴位于细胞质中。KvSOS1基因编码蛋白与雷蒙德氏棉、可可和陆地棉SOS1蛋白的氨基酸序列同源性很高,分别为86%、82%和82%。系统进化树分析显示KvSOS1基因编码蛋白与质膜Na+/H+转运蛋白、液泡膜Na+/H+逆向转运蛋白(NHX)属于不同分支。同时将KvSOS1基因构建入植物表达载体pBI121中,并成功转入农杆菌LBA4404中。
